Startup Equity in Turkey: How Should Founders Divide Company Shares?

Dividing equity is one of the earliest and most important decisions startup founders make.

At the beginning of a startup, the company may have:

• no revenue,
• no employees,
• no customers,
• no investment, and
• no significant market value.

The founders may therefore view share percentages as theoretical numbers.

This can be a serious mistake.

If the startup succeeds, the equity allocated during the first weeks of the business may later represent millions of dollars in value and determine who controls critical decisions concerning investment, management and exit.

A 5% difference that appears insignificant when the company is formed can become commercially significant after several financing rounds.

Founder equity should therefore not be divided simply because:

“There are two founders, so we should each receive 50%.”

or:

“There are three founders, so everyone should receive one-third.”

An equal split may be appropriate in some startups, but it should be the result of deliberate analysis rather than convenience.

For startups established in Turkey, founders must also consider the corporate law consequences of share percentages. Ownership affects not only economic participation but potentially voting power, management, minority rights, capital increases, dilution, future investment and exit transactions.

This guide explains how startup founders in Turkey can approach equity allocation, which factors should be considered, why vesting matters, how dilution affects founder ownership and how founders can avoid common cap table mistakes.

What Is Startup Equity?

Startup equity represents ownership in the company.

If a founder owns 40% of the shares, that founder generally holds an economic interest corresponding to 40% of the company, subject to:

• share classes,
• privileges,
• dilution,
• investment rights,
• liquidation preferences,
• contractual arrangements, and
• applicable corporate law.

Equity may provide rights relating to:

• voting,
• dividends,
• company value,
• future sale proceeds,
• capital increases,
• management influence, and
• certain shareholder protections.

However, owning 40% of a startup does not necessarily mean receiving 40% of every payment made in connection with the company.

For example, investor liquidation preferences or different share rights may affect how exit proceeds are distributed.

Founder equity should therefore be understood within the broader capital structure.

Why Founder Equity Allocation Matters

Founder equity affects several fundamental aspects of a startup.

These include:

Economic Ownership

How much of the future company value belongs to each founder?

Control

Who can influence shareholder decisions?

Motivation

Do founders believe their ownership reflects their contribution?

Fundraising

Will the founder cap table appear reasonable to investors?

Dilution

How much ownership will each founder retain after future investment rounds?

Founder Departure

What happens if one founder stops contributing?

Exit

How will founders participate if the company is sold?

Equity allocation should therefore support both the current founder relationship and the startup’s future financing strategy.

Is Equal Equity Always Fair?

No.

Equal equity and fair equity are not necessarily the same thing.

Suppose two founders establish a startup.

Founder A:

• developed the technology for twelve months before incorporation,
• works full-time,
• invested USD 100,000 personally,
• acts as CEO, and
• has industry connections.

Founder B:

• joined one week before incorporation,
• works part-time,
• contributes marketing expertise, and
• made no financial investment.

A 50/50 allocation may not accurately reflect the respective contributions.

In another startup, however, two founders may:

• join at the same time,
• both work full-time,
• contribute equally important skills,
• accept similar financial risk, and
• share responsibility equally.

A 50/50 arrangement may then be entirely appropriate.

The relevant question is therefore not:

Should founders divide shares equally?

The better question is:

What allocation reflects past contribution, future contribution, risk and the long-term needs of the startup?

Factors to Consider When Dividing Founder Equity

There is no statutory formula requiring startup shares to be divided according to a specific method.

Founders can evaluate several factors.

1. The Original Idea

Who developed the original business idea?

This may deserve consideration, but founders should avoid overvaluing the idea itself.

Startups generally become valuable through execution.

An idea without:

• product development,
• customers,
• team building,
• capital,
• execution, and
• market adoption

may have limited standalone value.

Therefore, the founder who first suggested the idea should not automatically receive the majority of the company.

The practical value of the idea should be evaluated together with everything required to turn it into a functioning business.

2. Work Performed Before Incorporation

Some founders may have already spent significant time developing the startup before the company is formally established.

For example, one founder may have:

• developed the minimum viable product,
• written source code,
• created a prototype,
• filed a patent application,
• acquired initial customers, or
• negotiated commercial partnerships.

This contribution may justify additional equity.

However, founders should carefully document intellectual property ownership where work was completed before incorporation.

The company should ultimately obtain appropriate rights over technology and other assets used in its business.

3. Future Time Commitment

Founder equity should not be based entirely on the past.

A startup’s future value will usually be created through future work.

A founder who intends to work full-time for five years may reasonably receive more equity than a founder providing several hours of assistance each month.

The founders should therefore discuss:

• full-time commitment,
• part-time commitment,
• expected working hours,
• duration of involvement, and
• other professional activities.

A large equity grant based on a promised future contribution should generally be protected by vesting.

4. Financial Contributions

A founder may contribute significant capital to the company.

For example:

Founder A contributes USD 250,000.

Founder B contributes technical expertise but no cash.

How should equity be divided?

There is no single correct answer.

The cash contribution could be treated as:

• equity,
• shareholder loan,
• additional capital contribution,
• convertible financing, or
• part of the founder’s overall contribution.

The parties should distinguish between ownership earned through founder contribution and money provided as financing.

Otherwise, one founder may later argue that money provided to the company should be repaid even though the other founders believed it was exchanged for additional equity.

5. Intellectual Property Contributions

One founder may contribute valuable intellectual property.

Examples include:

• existing software,
• algorithms,
• patents,
• trademarks,
• designs,
• databases, or
• proprietary technology.

If the startup depends heavily on that IP, the contribution may justify a larger ownership position.

However, the founders should determine whether the IP will be:

• transferred to the company,
• licensed to the company, or
• retained by the founder.

Investors will generally prefer the startup itself to own or securely control its core intellectual property.

6. Technical Expertise

In technology startups, highly specialized technical expertise may be difficult to replace.

A founder who can build the product may therefore make a particularly valuable contribution.

However, technical contribution should not automatically be considered more valuable than:

• customer acquisition,
• sales,
• fundraising,
• regulatory expertise, or
• operational leadership.

Successful startups often require several complementary founder profiles.

Equity should reflect the contribution necessary to build the entire business rather than only the product.

7. Business Development and Customer Relationships

A founder may bring:

• major customers,
• distribution relationships,
• strategic partnerships,
• industry contacts, or
• commercial contracts.

These contributions can materially reduce startup risk.

However, founders should distinguish between:

• actual relationships producing commercial value, and
• general claims such as “I know many people in the industry.”

Equity should preferably reflect measurable contribution rather than hypothetical future introductions.

8. Fundraising Ability

Fundraising can be one of the CEO’s most important responsibilities.

A founder who can:

• access investors,
• negotiate investment,
• manage due diligence, and
• develop institutional relationships

may contribute significantly to the company’s ability to scale.

However, raising investment should not necessarily be treated as a one-time event deserving permanent disproportionate equity.

The allocation should consider the founder’s broader long-term role.

9. Opportunity Cost

A founder leaving a high-paying position to work on the startup may incur significant opportunity cost.

For example:

Founder A leaves a senior executive position paying USD 200,000 annually.

Founder B continues working elsewhere while contributing to the startup part-time.

This difference in risk may justify different equity treatment.

Opportunity cost should be considered alongside:

• salary,
• time commitment,
• financial contributions, and
• future role.

10. Personal Financial Risk

Some founders personally guarantee obligations or use personal savings to finance the startup.

Such risk may deserve consideration.

However, personal financing should be documented properly.

Founders should avoid situations where equity percentages are informally adjusted every time someone pays a company bill.

11. Founder Responsibilities

Founder roles may include:

• CEO,
• CTO,
• COO,
• CMO,
• CFO,
• product leadership,
• regulatory leadership, or
• business development.

Equity should not necessarily depend on job title alone.

The founders should assess the actual importance and expected contribution of each role.

12. Experience and Track Record

A founder with substantial industry experience may create value by:

• attracting investors,
• hiring employees,
• negotiating enterprise contracts,
• building credibility, and
• avoiding operational mistakes.

However, experience should be valued according to its relevance to the startup.

Twenty years of experience in an unrelated industry may not justify significantly more startup equity.

13. Network and Reputation

A founder’s professional reputation can benefit the startup.

This may help with:

• investor access,
• customer acquisition,
• recruiting,
• partnerships, and
• media visibility.

However, a network should be evaluated realistically.

Founders should avoid allocating substantial equity for vague promises of future introductions.

Equal Split Between Two Founders

The 50/50 model is extremely common.

It can work where both founders:

• join at approximately the same time,
• work full-time,
• assume similar risks,
• contribute complementary skills, and
• expect to remain equally involved.

However, 50/50 ownership creates a potential governance problem.

If shareholders disagree, neither side may have sufficient voting power to resolve the issue.

This is known as deadlock.

A 50/50 company should therefore consider a deadlock mechanism.

Possible mechanisms may include:

• escalation,
• mediation,
• qualified third-party involvement,
• buy-sell procedures,
• or other contractual mechanisms.

Equal equity without a deadlock solution can create serious problems.

51/49 Founder Equity Split

Some founders use a 51/49 split simply to avoid deadlock.

This may give one founder majority control over decisions requiring a simple majority.

However, founders should understand that a 1% difference can have significant governance consequences.

The 49% founder should therefore understand exactly:

• which decisions can be made by the 51% shareholder,
• which decisions require a qualified majority,
• which matters are reserved, and
• what protections minority shareholders retain.

A 51/49 arrangement should not be used casually.

Three-Founder Equity Split

Three founders may initially consider:

• 33.33%,
• 33.33%,
• 33.34%.

This can be reasonable if contributions are genuinely comparable.

However, startups frequently have different founder roles.

For example:

CEO: 40%
CTO: 40%
COO: 20%

or:

CEO: 45%
CTO: 35%
Business Founder: 20%

There is no universally correct ratio.

The founders should examine the factors relevant to their own startup.

Four or More Founders

Equity becomes increasingly difficult to manage as the number of founders increases.

For example, five founders receiving 20% each may create a highly fragmented management structure.

Questions arise concerning:

• decision-making,
• vesting,
• inactive founders,
• board representation,
• future dilution, and
• investor expectations.

Founders should therefore consider whether every early contributor truly needs founder-level equity.

Some individuals may be more appropriately compensated through:

• salary,
• consulting fees,
• employee options,
• advisor equity, or
• performance incentives.

Calling every early contributor a founder can create long-term cap table problems.

What Is a Cap Table?

A capitalization table, or cap table, records the ownership of the startup.

A basic cap table may show:

Shareholder	Ownership
Founder A	50%
Founder B	30%
Founder C	20%

As the startup grows, the cap table may also include:

• angel investors,
• venture capital funds,
• employee option pools,
• advisors,
• convertible investors, and
• strategic shareholders.

Maintaining an accurate cap table is essential.

Investors will examine it during due diligence.

Fully Diluted Ownership

Startup founders should understand the concept of fully diluted ownership.

Suppose:

Founder A: 50%

Founder B: 40%

Issued Investor Shares: 10%

However, the company also has an employee option pool equal to 10% on a fully diluted basis.

The founders’ actual economic percentages after all reserved equity is considered may therefore be lower than the headline issued-share percentages.

Investment negotiations often refer to fully diluted ownership.

Founders should understand which calculation is being used.

Founder Vesting Is Essential to Equity Allocation

One of the most important principles of founder equity is that future contribution should usually be connected to vesting.

Suppose Founder A receives 40%.

Founder A leaves after three months.

If the shares are unconditional, Founder A may remain a 40% shareholder permanently.

A vesting structure may prevent this.

A common international model is:

• four-year vesting,
• one-year cliff,
• monthly vesting thereafter.

The structure must be adapted carefully to Turkish corporate law.

Reverse Vesting for Founders

Founders often receive shares at incorporation rather than acquiring them gradually.

Therefore, startup agreements may use reverse vesting.

Under reverse vesting:

• the founder initially owns the shares,
• part remains unvested,
• unvested shares become subject to transfer if the founder leaves early.

The agreement should specify:

• vesting schedule,
• leaver events,
• purchaser,
• transfer price,
• exercise mechanism, and
• corporate formalities.

A vague statement that “shares vest over four years” is generally insufficient.

Why Investors Care About Founder Equity

Investors examine the founder cap table very carefully.

They may become concerned if:

• an inactive founder owns 40%,
• advisors own excessive percentages,
• founder equity is not vested,
• employees were promised undocumented shares,
• one founder has overwhelming control,
• previous investors have unusual rights, or
• ownership records are unclear.

These issues may affect:

• valuation,
• investment structure,
• investor confidence, and
• closing conditions.

A clean cap table can therefore make fundraising significantly easier.

What Percentage Should the CEO Own?

There is no universal rule.

The CEO does not automatically need to own the largest percentage.

However, investors often expect the founders who are most important to the company’s future success to retain meaningful ownership.

A startup in which the full-time CEO owns only 3% while an inactive original founder owns 60% may raise obvious concerns.

The ownership structure should align incentives with the individuals creating future company value.

What Percentage Should the CTO Own?

Again, there is no standard percentage.

A technical co-founder who:

• joins before incorporation,
• builds the entire product,
• works full-time, and
• remains responsible for technology

may reasonably hold a substantial founder stake.

By contrast, a developer who is hired after incorporation to implement a defined technical project may be more appropriately treated as:

• employee,
• contractor, or
• option holder

rather than a co-founder.

The distinction between a co-founder and early employee should be made carefully.

How Much Equity Should an Advisor Receive?

Advisors generally receive substantially less equity than founders.

The appropriate amount depends on:

• startup stage,
• advisor reputation,
• time commitment,
• strategic value, and
• duration of involvement.

Advisor equity should normally be subject to vesting.

Giving an advisor a permanent 5% or 10% interest for occasional advice may create severe cap table problems later.

The agreement should clearly state:

• percentage,
• vesting,
• duties,
• termination consequences, and
• whether the interest is actual shares or another instrument.

Employee Equity

Startups may reserve part of the company’s equity for employees.

This is commonly known as an Employee Stock Option Pool, or ESOP pool.

A startup may reserve, for example:

• 5%,
• 10%,
• 15%, or
• another percentage

for future employee incentives.

The appropriate size depends on:

• hiring plans,
• company stage,
• financing strategy, and
• investor expectations.

Founders should understand that creating an option pool usually dilutes existing shareholders.

The Option Pool Shuffle

Option pool treatment can significantly affect founder economics during an investment round.

Suppose a startup is valued at USD 9 million pre-money.

The investor will invest USD 1 million.

The investor also requires a 10% employee option pool to be created before the investment.

If founders assume the investor will share the dilution proportionally, they may be surprised.

Where the option pool is included in the pre-money capitalization, much of the dilution may fall on existing founders.

This is sometimes referred to in startup finance as the option pool shuffle.

Founders should calculate the fully diluted cap table before signing a term sheet.

Dilution After Investment

Founder ownership decreases when new shares are issued.

For example:

Incorporation

Founder A: 60%
Founder B: 40%

Seed Investment

Founder A: 48%
Founder B: 32%
Seed Investor: 20%

Series A

Founder A: 36%
Founder B: 24%
Seed Investor: 15%
Series A Investor: 25%

Founder A has moved from 60% to 36%.

This is not necessarily negative.

If the company is now worth significantly more, the economic value of Founder A’s ownership may have increased substantially.

Dilution Is Not the Same as Losing Value

Consider:

Founder owns 80% of a startup worth USD 1 million.

Founder’s theoretical interest: USD 800,000.

After investment:

Founder owns 50% of a company worth USD 10 million.

Founder’s theoretical interest: USD 5 million.

The founder’s percentage decreased but economic value increased.

Founders should therefore focus on both:

• percentage ownership, and
• total company value.

Control Can Be Diluted Faster Than Economic Value

Even where dilution increases economic value, it may reduce founder control.

A founder who owns 60% before investment may have majority voting power.

After several rounds, that founder may own only 25%.

Control may then depend on:

• board composition,
• voting agreements,
• reserved matters,
• share privileges, and
• shareholder alliances.

Founders should therefore evaluate governance and economics separately.

Pre-Emption Rights

Existing shareholders may have rights to participate in future capital increases.

These rights can allow founders to maintain ownership percentages by investing additional capital.

For example:

Founder owns 40%.

The company issues new shares.

The founder may have the opportunity to invest proportionally and preserve the 40% position, subject to applicable law and agreements.

However, founders may not always have sufficient capital to exercise these rights.

Anti-Dilution Rights

Investors may receive anti-dilution protection if future shares are issued at a lower valuation.

For example:

Seed Investor invests at a USD 10 million valuation.

Series A occurs at a USD 5 million valuation.

The seed investor may have contractual protection adjusting the economic consequences.

Anti-dilution mechanisms may include:

• weighted average protection, or
• full ratchet protection.

These rights can create additional dilution for founders.

Therefore, founder equity should be evaluated not only by current percentages but also by contractual investor rights.

Liquidation Preference and Founder Economics

A founder may own 70% of a startup but still receive significantly less than 70% of a low-value exit if investors hold liquidation preferences.

For example:

Investor invests USD 5 million for 30%.

The investor receives a 1x liquidation preference.

The startup later sells for USD 6 million.

The investor may be entitled to recover its investment before the remaining proceeds are distributed, depending on the precise structure.

Therefore, ownership percentage alone does not determine exit economics.

Founders should understand the entire investment waterfall.

Avoid Giving Too Much Equity Too Early

One of the most common startup mistakes is giving away substantial equity during the earliest stage.

Examples include:

• 10% to an advisor,
• 15% to an early developer,
• 10% to someone who introduced one customer,
• 5% to a consultant, and
• 5% to another early supporter.

The founders may quickly discover that 45% of the company has been allocated before any professional investor arrives.

Investors may then require restructuring.

Early equity should be treated as an extremely scarce resource.

Cash compensation may sometimes be more appropriate.

Informal Equity Promises

Statements such as:

“We will give you 2%.”

can create significant problems.

Questions include:

• 2% of issued shares?
• 2% fully diluted?
• Before or after investment?
• Subject to vesting?
• Actual shares or stock options?
• What happens if the person leaves?
• Does the percentage dilute in future rounds?
• When will the interest legally arise?

Equity promises should therefore be documented precisely.

WhatsApp conversations and informal emails should not function as the startup’s cap table.

Founder Equity Should Be Documented Properly

The actual share ownership must be reflected through appropriate corporate documentation.

Depending on the startup’s legal form, this may involve:

• articles of association,
• trade registry documents,
• share ledger,
• capital commitments,
• share certificates,
• shareholder resolutions,
• share transfer agreements, and
• investment documentation.

A spreadsheet showing ownership percentages does not itself necessarily establish legal ownership.

The cap table must correspond with corporate records.

Equity in a Turkish Joint Stock Company

A Turkish Anonim Şirket (A.Ş.) is commonly preferred for venture-backed startups.

The structure can offer flexibility regarding:

• share groups,
• privileges,
• board representation,
• capital increases,
• employee equity,
• investment rounds, and
• future share transfers.

For this reason, founders expecting venture capital investment should consider the share structure at incorporation.

The company should not be designed only for today’s founder ownership.

It should also accommodate tomorrow’s investors.

Equity in a Turkish Limited Liability Company

A Limited Şirket (Ltd. Şti.) can also be used by startups.

However, share transfers are more formal and the structure may be less convenient for sophisticated venture capital arrangements.

A startup expecting:

• multiple investment rounds,
• regular cap table changes,
• institutional investors, or
• sophisticated employee equity

may therefore consider whether an A.Ş. is a more appropriate long-term structure.

Economic Rights vs. Voting Rights

Equity does not always need to produce identical economic and governance rights.

For example, Turkish corporate law may permit certain share privileges in an A.Ş. subject to statutory limitations.

An investor may own 20% economically but receive specific rights regarding:

• board nomination,
• voting,
• dividends, or
• reserved matters.

Founders should therefore distinguish between:

economic percentage and corporate control.

A shareholder with a smaller percentage may still possess significant contractual or corporate influence.

Minority Shareholder Considerations

Founders sometimes assume that owning more than 50% means complete control.

This is overly simplistic.

Turkish corporate law provides statutory protections for shareholders and may require higher thresholds for certain decisions.

In addition, Shareholders’ Agreements may provide investors with:

• veto rights,
• board rights,
• information rights, or
• approval rights.

A 60% founder may therefore still need investor approval for major matters.

Founder Equity and Board Seats

Board representation should not necessarily mirror ownership exactly.

For example:

Founder A: 40%
Founder B: 30%
Investor: 30%

The board might consist of:

• one Founder A nominee,
• one Founder B nominee,
• one investor nominee.

Alternatively, the founders may collectively appoint two members while the investor appoints one.

Board structure is a negotiation independent from pure ownership percentage.

Founder Equity and Salaries

Founders should not use equity to replace every discussion about compensation.

Ownership and salary are different.

A founder may receive:

• significant equity but low salary during the early stage, or
• lower equity but market salary after substantial funding.

The Founders’ Agreement should clarify:

• salaries,
• expense reimbursement,
• bonuses, and
• equity.

Otherwise, one founder may later argue that additional salary should compensate for lower equity.

Founder Equity and Loans

A founder who lends money to the startup should document the transaction separately.

For example:

Founder A owns 50%.

Founder B owns 50%.

Founder A lends the company USD 200,000.

Founder A does not automatically become entitled to more shares unless that was expressly agreed.

The USD 200,000 may remain a company debt owed to Founder A.

Founders should avoid mixing:

• share ownership,
• capital contribution, and
• shareholder loans.

Sweat Equity

“Sweat equity” refers to ownership granted in exchange for work, expertise or other non-cash contribution.

This concept is common in startup negotiations.

For example, a technical founder may receive substantial equity because the founder spends two years developing the company’s technology without receiving market salary.

The economic reasoning is understandable.

However, the legal implementation must comply with the corporate rules applicable to the Turkish company.

Founders should therefore distinguish the commercial concept of sweat equity from the formal rules governing capital contributions and share ownership.

Dynamic Equity Splits

Some early-stage founders use dynamic formulas where ownership changes based on ongoing contributions.

For example, founders may receive points for:

• working hours,
• capital contributions,
• customer introductions, or
• intellectual property.

At a future date, the points are converted into ownership percentages.

Such models can be useful before incorporation but may become complicated once formal shares have been issued.

In Turkish companies, legal ownership cannot simply fluctuate every week based on an informal spreadsheet without appropriate corporate procedures.

Dynamic models should therefore be used carefully.

Setting a Founder Equity Review Date

Where the founders are uncertain about long-term contributions, one approach is to delay final allocation until certain milestones are reached.

Another approach is to establish:

• provisional economic arrangements,
• vesting, or
• milestone-based allocations.

However, once formal shares are issued, reallocating them may involve:

• share transfers,
• tax consequences,
• corporate approvals, and
• formal documentation.

It is generally better to use vesting than repeatedly change ownership.

Milestone-Based Equity

Certain founder equity may depend on achieving specific milestones.

For example:

A founder receives:

• 10% at incorporation,
• 5% after product launch,
• 5% after reaching USD 1 million ARR.

Milestone-based structures can be useful where future contributions are uncertain.

However, milestones must be objectively measurable.

Terms such as:

“Founder receives another 5% if the startup becomes successful.”

are too vague.

The agreement should define:

• the milestone,
• measurement date,
• evidence,
• who determines achievement, and
• what happens in disputed cases.

Founder Equity and Intellectual Property

Founders should avoid a structure where a founder receives significant equity while continuing to personally own the startup’s essential technology.

For example:

Founder A receives 40% for developing software but keeps the software personally and merely allows the company to use it informally.

An investor may view this as a serious risk.

If Founder A leaves, the company’s entire product could be affected.

Core IP should generally be transferred or securely licensed to the company through proper documentation.

Founder Equity and Investor Due Diligence

During legal due diligence, investors may review:

• articles of association,
• shareholder structure,
• cap table,
• share ledger,
• capital payments,
• share certificates,
• founder agreements,
• vesting,
• previous transfers,
• employee options, and
• informal equity promises.

Any inconsistency may delay investment.

For example:

The cap table says Founder A owns 40%.

Corporate records show 45%.

A former advisor claims another 5%.

An employee has an email promising 3%.

The investor cannot determine what it is actually buying.

Maintaining clean ownership documentation is therefore essential.

How Much Equity Should Founders Keep Before Seed Investment?

There is no mandatory percentage.

However, professional investors generally expect the founding team to retain sufficient equity to remain strongly motivated after future dilution.

If founders have already given away most of the company before the first institutional investment, the cap table may appear unhealthy.

For example:

Founders: 35%
Advisors: 15%
Early Investors: 40%
Others: 10%

Before even reaching Series A, the founding team may already own only 35%.

After additional financing, founder ownership could become very small.

Investors may question whether the founders remain adequately incentivized.

How Much Dilution Is Normal in an Investment Round?

There is no fixed legal rule.

A financing round may result in investors receiving:

• 10%,
• 15%,
• 20%,
• 25%, or
• another negotiated percentage.

The outcome depends on:

• company valuation,
• investment amount,
• bargaining power,
• startup stage,
• growth,
• market conditions, and
• investor rights.

Founders should model several future financing scenarios before agreeing to an early-stage cap table.

Cap Table Scenario

Assume two founders begin with:

Founder A: 60%
Founder B: 40%

Seed Round

Investor receives 20%.

New cap table:

Founder A: 48%
Founder B: 32%
Seed Investor: 20%

ESOP Pool

A 10% employee pool is created through dilution.

Approximate fully diluted ownership:

Founder A: 43.2%
Founder B: 28.8%
Seed Investor: 18%
ESOP: 10%

Series A

Series A Investor receives 25%.

Approximate ownership after the round:

Founder A: 32.4%
Founder B: 21.6%
Seed Investor: 13.5%
ESOP: 7.5%
Series A Investor: 25%

Founder A has moved from 60% to approximately 32.4%.

Founder B has moved from 40% to approximately 21.6%.

This illustrates why founders should think several rounds ahead when allocating initial equity.

What Happens If One Founder Leaves?

Founder departure is where poor equity allocation becomes particularly dangerous.

Suppose:

Founder A: 50%
Founder B: 50%

Founder B leaves after four months.

No vesting agreement exists.

Founder B may potentially remain a 50% shareholder.

By contrast, if shares are subject to properly structured reverse vesting, the unvested portion may become subject to transfer according to the agreed mechanism.

Founder equity and founder vesting should therefore be designed together.

Good Leaver and Bad Leaver Rules

Founder agreements may classify departures differently.

A Good Leaver may include someone leaving because of:

• death,
• disability,
• termination without cause, or
• mutually agreed departure.

A Bad Leaver may include someone leaving after:

• fraud,
• serious contractual breach,
• unlawful competition,
• misuse of company assets, or
• serious misconduct.

These classifications may affect:

• vested shares,
• unvested shares,
• purchase rights, and
• transfer price.

The clauses should be proportionate and carefully drafted.

Do Founders Need a Shareholders’ Agreement?

Yes, where appropriate.

A Shareholders’ Agreement or Founders’ Agreement may regulate:

• founder equity,
• vesting,
• roles,
• decision-making,
• share transfers,
• pre-emption,
• drag-along,
• tag-along,
• deadlock,
• future investment,
• founder departure, and
• exit.

However, contractual provisions should be coordinated with the company’s articles of association and mandatory Turkish corporate law.

Common Founder Equity Mistakes

Automatically Splitting 50/50

Equal ownership should reflect equal contribution and risk, not merely convenience.

No Vesting

An early-departing founder may retain excessive ownership.

Giving Advisors Too Much Equity

Small early grants become very valuable if the startup succeeds.

Informal Equity Promises

Undocumented commitments create due diligence problems.

Ignoring Future Dilution

Founders focus only on today’s ownership percentage.

No Employee Option Pool Planning

The pool may create unexpected founder dilution.

Confusing Salary With Equity

They compensate different forms of contribution.

Mixing Founder Loans and Equity

Money advanced to the company should be documented separately.

Failing to Transfer IP

The startup’s technology may remain personally owned by a founder.

Ignoring Control Rights

Percentage ownership alone does not determine governance.

No Deadlock Mechanism

This is especially dangerous in 50/50 startups.

No Legal Documentation

The cap table and official corporate records must match.

Founder Equity Checklist

Before finalizing founder ownership, startups should consider:

• original idea,
• prior work,
• technology developed,
• intellectual property,
• financial contribution,
• time commitment,
• full-time or part-time involvement,
• future responsibilities,
• opportunity cost,
• industry expertise,
• customer relationships,
• fundraising responsibilities,
• founder salaries,
• vesting,
• cliff period,
• Good Leaver rules,
• Bad Leaver rules,
• deadlock,
• decision-making,
• employee option pool,
• advisor equity,
• future dilution,
• investment rounds,
• board composition,
• transfer restrictions,
• pre-emption rights,
• drag-along rights,
• tag-along rights,
• IP ownership,
• shareholder loans, and
• exit scenarios.

The correct equity split should emerge from an analysis of the entire relationship.

Practical Example 1: Two Equal Co-Founders

Founder A is CEO.

Founder B is CTO.

Both:

• join at the same time,
• work full-time,
• take no salary,
• contribute complementary skills, and
• expect to remain for at least four years.

A 50/50 arrangement may be commercially reasonable.

However, the founders should still establish:

• vesting,
• deadlock procedures,
• IP ownership,
• management responsibilities, and
• founder departure rules.

Practical Example 2: Original Founder and New Co-Founder

Founder A:

• developed the idea,
• built the first product,
• invested USD 100,000,
• worked for eighteen months.

Founder B joins later as commercial co-founder.

Founder B brings significant industry experience but has not yet contributed to the startup.

An immediate 50/50 split may not reflect prior contribution.

The parties might instead consider:

• unequal initial equity,
• Founder B vesting over time, or
• milestone-based additional equity.

Practical Example 3: Technical Founder and Investor-Founder

Founder A develops the technology full-time.

Founder B provides USD 500,000 but does not work operationally.

The parties should determine whether Founder B is truly a co-founder or primarily an early investor.

Treating the entire USD 500,000 as founder contribution without identifying an investment valuation may create confusion.

It may be more appropriate to structure Founder B’s position through a defined investment transaction.

Practical Example 4: Three Founders

Founder A: CEO and fundraising
Founder B: CTO and product development
Founder C: sales and partnerships

After analyzing:

• time commitment,
• prior contributions,
• future responsibilities, and
• business risk,

the parties agree:

Founder A: 40%
Founder B: 40%
Founder C: 20%

All founder shares are subject to a four-year reverse vesting structure.

The lower percentage allocated to Founder C is therefore based on expected contribution rather than title.

Can Founder Equity Be Changed Later?

Yes, but it can become complicated.

Changing founder ownership may require:

• share transfers,
• capital increases,
• contractual arrangements,
• corporate approvals,
• amendments to records,
• tax analysis, and
• potentially investor consent.

It is therefore preferable to design the initial structure carefully.

Vesting often provides more flexibility than constantly transferring shares between founders.

Tax Consequences of Founder Share Transfers

Founder share reallocations may create tax consequences.

The result may depend on factors including:

• company type,
• shareholder identity,
• holding period,
• transfer price,
• residency,
• whether share certificates exist, and
• applicable tax rules.

Founders should therefore obtain tax advice before transferring significant equity merely to “rebalance” the cap table.

Equity Should Be Negotiated Before the Company Becomes Valuable

The best time to discuss equity is before:

• substantial revenue,
• investment,
• major customers, or
• significant valuation.

When the startup has little value, founders can discuss contribution more objectively.

Once the business becomes worth millions, even a 1% adjustment may represent a significant amount of money.

Equity discussions then become much more difficult.

What Should Founders Put in Writing?

At minimum, founders should clearly document:

• ownership percentages,
• vesting,
• roles,
• expected contribution,
• salaries,
• IP ownership,
• share transfer restrictions,
• departure rules,
• decision-making,
• deadlock,
• future fundraising, and
• treatment of employee and advisor equity.

The documentation should then be coordinated with formal corporate records.

Conclusion

Dividing startup equity is not simply a mathematical exercise.

It is a long-term decision concerning:

• ownership,
• control,
• motivation,
• investment readiness,
• founder relationships, and
• future exit economics.

There is no universal founder equity formula under Turkish law.

A 50/50 split may be appropriate for two genuinely equal co-founders.

A 60/40 or 70/30 structure may be more appropriate where contributions, risks or commitments are materially different.

The founders should evaluate:

• what has already been contributed,
• what each founder will contribute in the future,
• how long each founder is expected to remain,
• how much personal risk each founder assumes, and
• how the cap table will evolve through future investment rounds.

Most importantly, founder equity should generally be considered together with vesting.

If a founder receives a substantial percentage based on future contribution, the company should have a mechanism addressing what happens if that contribution never occurs.

Founders should also remember that initial ownership is only the beginning.

The cap table may later include:

• angel investors,
• venture capital funds,
• strategic investors,
• employee option pools, and
• additional financing instruments.

A founder who begins with 50% may own substantially less after several investment rounds.

This is normal.

The objective should not necessarily be to preserve the highest possible percentage forever.

The objective should be to build a valuable company while maintaining an ownership and governance structure that keeps founders, employees and investors properly incentivized.

A clean and carefully structured cap table can make fundraising easier, reduce founder disputes and support a future acquisition.

A poorly structured cap table can have the opposite effect.

For that reason, founder equity should be treated as one of the startup’s most important legal and strategic assets from the first day.
