Vesting Agreements for Startup Founders in Turkey: How Founder Equity Can Be Protected

Founder equity is one of the most valuable assets in a startup. At the same time, it can become one of the most serious sources of conflict.

A typical startup may begin with two or three founders who divide the company among themselves before the business has meaningful revenue, investment or market value. Each founder may initially promise to contribute technical expertise, business development, capital, industry relationships or full-time work.

But what happens if one founder leaves after six months?

Should that founder continue to own 30%, 40% or even 50% of the startup indefinitely?

This is the problem that founder vesting is designed to address.

Vesting structures are widely used in international startup transactions, particularly in venture capital-backed companies. Although the concept originates primarily from Anglo-American startup practice, vesting arrangements can also be structured for Turkish startups.

However, founders should not assume that a standard Silicon Valley vesting agreement can simply be copied and used in Turkey.

Turkish corporate law, contract law, share transfer rules and the legal form of the startup must all be taken into account.

This article explains how vesting agreements may be used for startup founders in Turkey, how reverse vesting works, what a one-year cliff means, how good leaver and bad leaver provisions operate and which legal issues founders and investors should consider when designing a vesting structure.

What Is Founder Vesting?

Founder vesting is a mechanism designed to link a founder’s long-term equity position to continued participation in the startup.

The commercial principle is straightforward:

A founder should generally earn the right to retain the full economic benefit of founder equity over time rather than receiving an unconditional long-term ownership position on the first day.

Consider the following example.

Two founders establish a startup.

Founder A owns 50%.

Founder B owns 50%.

Both promise to work full-time for at least four years.

Six months later, Founder B leaves the company permanently.

Founder A continues developing the startup for another four years.

The company raises investment and eventually becomes worth USD 20 million.

Without a vesting arrangement, Founder B may potentially continue to hold half of the company despite having contributed for only six months.

From the perspective of:

• Founder A,
• employees,
• future investors, and
• the startup itself,

this may create an extremely problematic ownership structure.

A vesting arrangement attempts to prevent such outcomes.

Why Do Startups Use Vesting?

Startups use vesting because the value of founder equity is usually based not only on what the founder contributed before incorporation but also on what the founder is expected to contribute in the future.

An investor evaluating a startup frequently invests substantially because of the founding team.

If a founder can receive a significant percentage of the company and immediately leave while keeping all shares, the company may be left with what investors sometimes describe as dead equity.

Dead equity refers to a substantial shareholding held by a person who no longer contributes meaningfully to the company.

This can create several problems.

It may:

• reduce the incentive of active founders,
• make employee option pools more difficult to establish,
• create governance disputes,
• discourage investors,
• complicate future fundraising, and
• reduce the amount of equity available for people who continue creating value.

Founder vesting is therefore fundamentally a risk allocation mechanism.

Is Founder Vesting Recognized Under Turkish Law?

Turkish legislation does not contain a standalone legal institution specifically called a “startup founder vesting agreement” in the same manner the concept is used in Silicon Valley documentation.

That does not mean vesting cannot be structured.

Instead, the economic objective of vesting must generally be implemented through legal mechanisms recognized under Turkish law.

Depending on the company structure and transaction, this may involve combinations of:

• contractual obligations,
• share transfer undertakings,
• call option mechanisms,
• conditional transfer obligations,
• founder agreements,
• shareholders’ agreements,
• contractual repurchase mechanisms,
• corporate resolutions, and
• provisions in the articles of association where legally permissible.

The precise structure is critical.

A clause stating merely:

“The founder’s shares shall vest over four years.”

may describe the commercial intention but may not, by itself, explain how ownership will legally change if the founder leaves.

A Turkish vesting agreement should therefore answer the implementation question:

Who has the right to acquire the unvested shares, under what circumstances, at what price and through which legally valid transfer procedure?

What Is Reverse Vesting?

In startup practice, founder vesting is commonly implemented through reverse vesting.

Under a conventional employee option arrangement, the employee may acquire shares gradually over time.

Founder structures are often different.

Founders frequently already own their shares from the beginning.

Reverse vesting therefore works in the opposite direction.

The founder initially holds the shares, but some of those shares remain subject to a contractual transfer or purchase mechanism if the founder leaves before completing the agreed vesting period.

For example:

Founder A receives 40% of the startup.

The 40% interest is subject to a four-year reverse vesting schedule.

After one year, 25% of the founder’s vesting interest becomes vested.

The remaining portion continues vesting over the next three years.

If Founder A leaves after two years, the founder may retain the vested portion while being required to transfer the unvested portion according to the agreed mechanism.

This allows the founder to hold shares from incorporation while still protecting the company against an early departure.

What Is a Four-Year Vesting Schedule?

A four-year vesting schedule is one of the most common structures in international startup transactions.

Under a simplified model:

• total vesting period: 48 months,
• first major vesting event: after 12 months,
• remaining equity: vests progressively over the following 36 months.

For example, assume a founder’s 32% interest is subject to four-year vesting.

If the parties agree to straight-line vesting, the founder economically earns approximately:

• 8% after the first year,
• 16% after two years,
• 24% after three years,
• 32% after four years.

The actual legal documentation may not describe the percentages in exactly this manner, depending on how the underlying share structure is implemented.

The principle remains the same: continued contribution leads to progressively greater protection of the founder’s equity.

What Is a One-Year Cliff?

A cliff is a minimum period during which the founder must remain involved before the first portion of equity becomes vested.

The most common example is a one-year cliff.

Suppose a founder receives 24% of a startup subject to:

• four-year vesting, and
• a one-year cliff.

If the founder leaves after five months, the founder may have no vested interest under the contractual schedule.

If the founder remains for twelve months, the first 25% of the vesting package may become vested.

After that, the remaining amount may vest monthly or quarterly.

The purpose of a cliff is to prevent a founder from receiving a permanent equity interest after only a very short period of participation.

Monthly vs. Quarterly Vesting

After the cliff, shares or economic rights may vest:

• monthly,
• quarterly,
• annually, or
• according to milestones.

Monthly vesting is common because it creates a gradual and predictable structure.

For example:

Four-year vesting
One-year cliff
Monthly vesting for remaining 36 months

This means that after the founder completes the first year, the remaining unvested interest becomes progressively protected each month.

Quarterly vesting is also possible.

The appropriate schedule depends on the startup’s circumstances.

Time-Based Vesting vs. Milestone-Based Vesting

Not every vesting arrangement must depend only on time.

Some startups use milestone-based vesting.

For example, a founder may receive additional equity when:

• a product is launched,
• specified annual recurring revenue is achieved,
• a financing round closes,
• a regulatory authorization is obtained,
• a certain number of customers is reached, or
• a technical milestone is completed.

A startup may also combine:

• time-based vesting, and
• performance-based vesting.

However, performance criteria should be objective.

A clause stating:

“Additional shares vest if the founder performs well.”

is likely to create disputes.

A clause based on a measurable target is significantly clearer.

Why Investors Require Founder Vesting

Founder vesting is frequently introduced during an investment round even if the founders did not originally use vesting.

A venture capital investor may say:

“We will invest, but the founders must be subject to four-year reverse vesting.”

Why?

Because the investor is often investing in the team’s future performance.

Suppose a VC fund invests USD 5 million into a company largely because of its CTO.

If the CTO could resign one day after closing while retaining 30% of the company, the investment risk would increase substantially.

Vesting therefore provides investors with greater certainty that founders will remain economically incentivized.

Can Investors Reset Founder Vesting?

Yes, this is sometimes negotiated.

For example, founders may have operated the startup for three years before institutional investment.

The investor may propose that the founders begin a new four-year vesting schedule at closing.

Founders may reasonably object that they have already spent years building the company.

A compromise may therefore involve vesting credit.

For example:

• 50% of founder shares are treated as already vested,
• the remaining 50% is subject to a new three-year vesting schedule.

Alternatively:

• a portion vests immediately,
• the balance is subject to continued service.

This is a commercial negotiation rather than a single mandatory legal rule.

Founder Vesting Should Not Be Confused With Employee Stock Options

Founder vesting and employee stock options serve related but different purposes.

Founder Vesting

The founder generally already has an ownership position, subject to contractual restrictions concerning continued participation.

Employee Stock Options

The employee may receive the right to acquire shares in the future after satisfying specified conditions.

The legal implementation may therefore be different.

Startup documentation should clearly distinguish:

• founder shares,
• employee shares,
• stock options,
• phantom equity, and
• contractual bonus rights.

Good Leaver and Bad Leaver Provisions

Vesting agreements commonly distinguish between founders who leave under acceptable circumstances and founders who leave under problematic circumstances.

These categories are usually described as:

• Good Leaver
• Bad Leaver

The distinction can determine:

• which shares the founder keeps,
• whether unvested shares must be transferred,
• how vested shares are treated,
• the applicable transfer price, and
• whether additional contractual remedies arise.

Who Is a Good Leaver?

The agreement should define the term precisely.

Depending on the transaction, a Good Leaver may include a founder who leaves because of:

• death,
• permanent incapacity,
• serious illness,
• termination without cause,
• mutual agreement,
• retirement approved by shareholders, or
• another circumstance expressly recognized by the agreement.

The founder may generally receive more favorable treatment.

For example, a Good Leaver may retain all vested shares while only unvested shares become subject to transfer.

In some arrangements, additional vesting may occur.

Who Is a Bad Leaver?

A Bad Leaver definition may include serious misconduct such as:

• fraud,
• embezzlement,
• theft of company assets,
• material breach of confidentiality,
• intentional misuse of intellectual property,
• serious breach of the shareholders’ agreement,
• unlawful competition,
• abandonment of duties,
• gross misconduct, or
• certain criminal conduct affecting the company.

The agreement should avoid definitions so broad that almost every departure becomes a Bad Leaver event.

A clause stating that any founder who resigns for any reason automatically becomes a Bad Leaver may create significant negotiation and enforceability concerns depending on the circumstances.

What Happens to Unvested Shares?

This is the central question in every vesting arrangement.

The parties must establish a legally workable mechanism.

Possible outcomes may include transfer of unvested shares to:

• another founder,
• existing shareholders,
• an investor,
• a designated shareholder, or
• potentially the company itself where the applicable corporate rules permit the contemplated acquisition.

The buyer and transfer mechanism must be chosen carefully.

A company cannot simply acquire its own shares without regard to statutory restrictions.

For this reason, international templates that state:

“The company automatically repurchases all unvested shares.”

should not be used in Turkey without corporate law analysis.

Can the Startup Buy Back the Founder’s Shares?

Potentially, but not without restrictions.

Turkish corporate law regulates when and to what extent companies may acquire their own shares.

The rules differ depending on whether the company is:

• a joint stock company, or
• a limited liability company.

Consequently, the company itself may not always be the most practical party to acquire unvested founder shares.

Alternative structures may designate:

• another founder,
• existing shareholders, or
• another agreed person

as the holder of the purchase or call option.

The correct mechanism depends on the company’s capital structure and the number of shares involved.

Call Options in Founder Vesting

A call option is one mechanism that may be used to implement reverse vesting.

A simplified structure may provide that, following a defined leaver event, a specified person has the right to purchase the founder’s unvested shares.

The agreement should specify:

• which shares are subject to the option,
• who holds the option,
• when it can be exercised,
• exercise period,
• purchase price,
• transfer procedure,
• required corporate approvals, and
• consequences if the founder refuses to cooperate.

The clause should also coordinate with applicable share transfer formalities.

Vesting in a Turkish Joint Stock Company

The joint stock company (Anonim Şirket – A.Ş.) is generally more suitable for complex startup equity arrangements than an Ltd. Şti., particularly where venture capital investment is expected.

An A.Ş. may offer greater flexibility concerning:

• share structures,
• different share groups,
• investor rights,
• share certificates,
• employee participation,
• capital increases, and
• future investment rounds.

However, vesting documentation still requires careful implementation.

The agreement should consider whether the relevant shares are:

• registered shares,
• bearer shares,
• certificated,
• uncertificated, or
• subject to transfer restrictions.

The articles of association and share ledger arrangements may also be relevant.

Vesting in a Turkish Limited Liability Company

A limited liability company can also use contractual arrangements intended to produce vesting effects.

However, share transfers in an Ltd. Şti. are subject to more formal procedural requirements.

The transfer of a limited liability company share generally requires a written transfer agreement with notarized signatures and may also require general assembly approval depending on the company’s articles of association and applicable rules.

This means that a vesting mechanism should not assume that an Ltd. Şti. share can simply be transferred automatically through a short contractual statement.

The required corporate formalities should be built into the structure.

For startups expecting sophisticated investor vesting arrangements, this is one of several reasons an A.Ş. may be more suitable.

Vesting and the Articles of Association

A major question is whether vesting provisions should appear only in:

• the Founders’ Agreement, or
• the Shareholders’ Agreement,

or whether certain elements should also be reflected in the articles of association.

The answer depends on the specific provision.

The articles of association cannot simply reproduce every contractual clause.

Turkish corporate law limits which provisions can create corporate effects.

However, certain mechanisms relating to:

• share groups,
• transfer restrictions,
• governance,
• privileges, or
• other corporate rights

may need to be coordinated with the articles.

The contractual and corporate documents should therefore be designed together.

Vesting and Shareholder Agreements

Once an investor enters the startup, founder vesting is typically integrated into the Shareholders’ Agreement.

The agreement may specify:

• each founder’s initial vested percentage,
• vesting commencement date,
• vesting period,
• cliff,
• monthly or quarterly schedule,
• Good Leaver events,
• Bad Leaver events,
• transfer price,
• call option holders,
• exercise procedure, and
• acceleration events.

It may also require founders to execute additional transfer documents at closing.

Can Founder Shares Be Automatically Cancelled?

Founders should be cautious with clauses stating that shares will simply “disappear,” “be cancelled” or “automatically return to the company” upon departure.

Company shares represent legal ownership interests.

Changes in ownership or capital must comply with applicable corporate procedures.

A contract can create obligations relating to the shares, but the legal method for implementing those obligations should also be defined.

A well-drafted agreement should therefore avoid relying entirely on vague automatic forfeiture terminology copied from another jurisdiction.

What Price Should Be Paid for Unvested Shares?

This is another major commercial issue.

Possible pricing methods include:

• nominal value,
• original subscription price,
• acquisition cost,
• fair market value,
• discounted fair market value, or
• another contractually defined price.

The treatment may differ between:

• vested shares,
• unvested shares,
• Good Leaver shares, and
• Bad Leaver shares.

For example:

Good Leaver

Vested shares: retained or transferred at fair market value.

Unvested shares: transferred at original acquisition price.

Bad Leaver

Vested and unvested shares may potentially be subject to different pricing rules depending on the negotiated agreement.

However, excessively punitive arrangements should be reviewed carefully under Turkish contract law.

How Is Fair Market Value Determined?

If shares must be purchased at fair market value, the agreement should define how that value will be calculated.

Possible mechanisms include:

• latest financing valuation,
• independent valuation expert,
• agreed accounting methodology,
• EBITDA multiple,
• revenue multiple,
• board determination subject to review, or
• another defined formula.

For early-stage startups, valuation can be difficult because the company may:

• have little revenue,
• generate losses,
• own valuable technology,
• have recently raised capital, or
• experience rapid changes in value.

Independent expert valuation may therefore be preferable in some situations.

Acceleration of Vesting

A vesting agreement may provide for accelerated vesting.

This means that some or all unvested equity becomes vested earlier than originally scheduled following a defined event.

Two major forms are commonly discussed.

Single-Trigger Acceleration

Under single-trigger acceleration, vesting accelerates following one specified event.

For example:

The startup is acquired.

Immediately upon acquisition, 50% of the founder’s remaining unvested equity becomes vested.

This protects the founder from losing unvested equity solely because the company is sold earlier than expected.

Investors may resist full single-trigger acceleration because it can reduce retention incentives after an acquisition.

Double-Trigger Acceleration

Double-trigger acceleration requires two events.

For example:

1. the company is acquired; and
2. within twelve months, the founder is dismissed without cause.

Only after both events occur does accelerated vesting apply.

This structure is often viewed as more balanced.

It protects founders if they lose their position following an acquisition while preserving incentives if they continue working for the buyer.

Vesting Following a Startup Exit

The agreement should clearly address what happens to unvested equity when the company is:

• sold,
• merged,
• acquired,
• reorganized, or
• taken public.

Possible approaches include:

• no acceleration,
• partial acceleration,
• full acceleration,
• continuation of vesting under the buyer,
• replacement with buyer equity, or
• cash compensation.

The correct structure depends on the bargaining position of founders and investors.

Vesting and Drag-Along Rights

Vesting also needs to be coordinated with drag-along provisions.

Suppose a founder owns both:

• vested shares, and
• shares still subject to reverse vesting.

If the majority triggers a drag-along sale, the documentation should clarify how both categories participate.

The founder should not be able to block an exit merely because some shares remain subject to vesting.

Similarly, the sale should not create uncertainty concerning the treatment of unvested equity.

Vesting and Tag-Along Rights

Tag-along rights may also need to specify whether the founder’s entire shareholding or only vested shares can participate in a third-party transfer.

This becomes particularly important where a founder attempts to sell shares while still subject to a lock-up or vesting schedule.

Vesting and Founder Lock-Up

Vesting and lock-up are different concepts.

Vesting

Determines how much founder equity becomes permanently protected over time.

Lock-Up

Restricts whether the founder can transfer shares during a specified period.

A founder may have fully vested shares but still be prohibited from selling them due to a lock-up.

Startup agreements frequently use both mechanisms.

Vesting and Non-Compete Obligations

A founder who leaves the startup may remain subject to contractual obligations concerning:

• confidentiality,
• trade secrets,
• customer solicitation,
• employee solicitation, and
• competition.

However, these obligations should be considered separately from vesting.

Forfeiture of equity should not be used as an unrestricted mechanism to impose legally excessive non-compete restrictions.

Post-termination restrictions must be assessed under applicable Turkish law.

What Happens if the Founder Is Dismissed?

A vesting agreement should distinguish between:

• voluntary resignation,
• termination for cause, and
• termination without cause.

Otherwise, investors or other founders might theoretically remove a founder shortly before a major vesting event.

For example:

A founder is scheduled to vest a significant portion of shares next month.

The board removes the founder today without wrongdoing.

If the contract simply states that vesting stops immediately upon termination, the founder may suffer an unfair economic loss.

A balanced agreement may provide:

• Good Leaver treatment,
• partial acceleration, or
• fair market value protection

when the founder is removed without cause.

Founder Vesting and Employment Status

A founder may simultaneously be:

• a shareholder,
• director,
• manager,
• employee,
• consultant, or
• several of these at the same time.

These legal capacities should not be confused.

Removing someone as CEO does not automatically remove them as a shareholder.

Terminating an employment agreement does not automatically cancel company shares.

Removing someone from the board does not necessarily affect equity ownership.

The vesting documents should therefore define exactly which event triggers the relevant share mechanism.

Death of a Founder

The vesting agreement should address what happens if a founder dies.

Possible questions include:

• Do vested shares pass to heirs?
• What happens to unvested shares?
• Does accelerated vesting apply?
• Do other shareholders have a purchase right?
• How is the purchase price determined?

Inheritance law and corporate transfer restrictions must also be considered.

A startup should avoid a situation where unexpected inheritance issues make future investment or governance impossible.

Permanent Disability or Incapacity

Similar issues arise where a founder becomes permanently unable to perform their role.

The agreement may treat permanent incapacity as a Good Leaver event.

The parties should define:

• what constitutes incapacity,
• who determines it,
• how long it must continue, and
• what happens to unvested shares.

Objective criteria can reduce future disputes.

Founder Vesting Before an Investment Round

A startup does not need to wait for an investor before establishing vesting.

Founders may create a vesting arrangement among themselves from the beginning.

This can be particularly useful where:

• founders have different experience levels,
• one founder is initially part-time,
• one founder is expected to leave another job later,
• technical milestones remain incomplete, or
• the founders do not yet know how long everyone will remain involved.

Early vesting may prevent substantial disputes later.

Example: Two-Founder Startup

Consider a Turkish SaaS startup.

Founder A: 60%
Founder B: 40%

Both founders agree to four-year reverse vesting with a one-year cliff.

After eighteen months, Founder B decides to leave.

Assume the agreement provides that approximately 37.5% of Founder B’s vesting package has become vested by that point.

Instead of Founder B retaining the entire 40% indefinitely, the vesting mechanism determines which portion Founder B may retain and which portion becomes subject to the agreed transfer mechanism.

This allows the active founder to continue building the company without a disproportionate amount of dead equity.

Example: Three Founders With Different Contributions

Assume:

Founder A: CEO – 40%
Founder B: CTO – 40%
Founder C: Business Development – 20%

Founder C is initially expected to become full-time within six months.

The founders may structure Founder C’s equity so that:

• part is subject to time-based vesting,
• part becomes vested when Founder C becomes full-time,
• another portion becomes vested upon completion of specified commercial milestones.

This may be more appropriate than granting the entire 20% unconditionally on incorporation.

Example: Investment Round

A startup has operated for two years.

Founder A: 55%
Founder B: 45%

A VC fund agrees to invest USD 4 million.

The investor requests four-year vesting beginning from closing.

The founders argue that they have already spent two years building the company.

The parties negotiate:

• 50% of founder equity deemed vested at closing,
• remaining 50% vesting over three years,
• no new cliff,
• double-trigger acceleration on a company sale.

This illustrates how vesting is often a negotiated commercial package rather than a fixed formula.

Is Four Years Always Necessary?

No.

Four years is common, not mandatory.

Depending on the startup, vesting may be:

• two years,
• three years,
• four years,
• five years, or
• milestone-based.

The appropriate period may depend on:

• company stage,
• founder contribution already completed,
• investment amount,
• founder bargaining power,
• expected exit horizon, and
• industry.

A founder joining an idea-stage startup may reasonably have a longer vesting period than a founder who has already spent five years building a profitable company.

Should Every Founder Have the Same Vesting Schedule?

Not necessarily.

Founders may have different:

• starting dates,
• prior contributions,
• ownership percentages,
• responsibilities, and
• time commitments.

For example, the CTO may have spent eighteen months building the product before the other founders joined.

The parties may therefore give that founder vesting credit.

However, materially different treatment should be documented clearly to avoid later misunderstandings.

Vesting for Advisors

Startups may also use vesting for advisors.

An advisor may be promised 1% of the company for providing strategic support over two years.

Instead of granting the entire 1% immediately, the startup may structure the benefit to vest:

• monthly,
• quarterly, or
• upon agreed milestones.

This prevents an advisor from retaining full equity after attending only a few meetings.

Advisor equity should also be coordinated with corporate and tax requirements.

Vesting for Employees

Employee equity plans often include vesting.

A common international employee structure may be:

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

However, Turkish startups should carefully design employee equity structures because taxation, employment law and corporate law implications may differ depending on whether the employee receives:

• actual shares,
• options,
• phantom shares, or
• cash-settled incentives.

Founder vesting should therefore not automatically be copied into an employee plan.

Tax Considerations

Vesting arrangements may create tax questions depending on:

• when shares are acquired,
• acquisition price,
• transfer price,
• whether the person is an employee,
• whether a benefit is provided below market value,
• future share sale, and
• whether the shareholder is resident in Turkey.

A legally valid corporate mechanism does not necessarily mean the transaction is tax neutral.

Legal and tax structuring should therefore be coordinated.

Foreign Founders and Turkish Vesting Agreements

Foreign founders may also be subject to Turkish startup vesting structures.

However, cross-border arrangements may raise additional questions involving:

• governing law,
• tax residency,
• foreign holding companies,
• foreign option plans,
• double taxation,
• currency,
• enforcement, and
• international shareholding structures.

This is especially important where the startup has:

• a Turkish operating company, and
• a foreign parent or holding company.

The vesting arrangement should identify precisely which company’s equity is subject to vesting.

Turkish Startup With a Foreign Holding Company

Some startups establish structures such as:

Foreign HoldCo
↓
Turkish Operating Company

If founder equity is held at the foreign HoldCo level, the vesting arrangement may primarily relate to the law governing that foreign company.

However, Turkish law may still be relevant to:

• employment,
• taxation,
• Turkish subsidiary management,
• IP transfers, and
• local founder obligations.

The legal structure should therefore be reviewed as a whole.

Governing Law of a Founder Vesting Agreement

International founders sometimes want to select:

• English law,
• Delaware law,
• Swiss law, or
• another foreign legal system.

A foreign governing law may potentially govern certain contractual obligations where legally permissible.

However, mandatory Turkish corporate law will remain relevant where the vesting mechanism requires changes to ownership in a Turkish company.

For example, a contract governed by English law cannot simply eliminate Turkish statutory requirements governing the transfer of an Ltd. Şti. share.

The governing law clause is therefore not a substitute for local corporate compliance.

Arbitration in Founder Vesting Disputes

Founder vesting disputes can involve substantial company value.

The parties may therefore consider arbitration.

Potential advantages include:

• confidentiality,
• specialist decision-makers,
• procedural flexibility, and
• international enforcement.

However, arbitration can be expensive.

Furthermore, certain corporate disputes may involve issues that require careful analysis concerning arbitrability and the effect of the award on corporate records.

The dispute resolution clause should therefore be tailored rather than copied from a generic template.

Documentation Required for a Vesting Structure

Depending on the transaction, a founder vesting package may involve more than one document.

These may include:

• Founders’ Agreement,
• Shareholders’ Agreement,
• Investment Agreement,
• call option agreement,
• share transfer undertaking,
• articles of association amendments,
• board resolutions,
• general assembly resolutions,
• share ledger arrangements,
• powers of attorney, and
• accession agreements.

Not every structure requires every document.

The implementation should reflect the company’s legal form and cap table.

Common Mistakes in Founder Vesting Agreements

Copying a Silicon Valley Template

A foreign template may describe the commercial idea correctly but fail to comply with Turkish share transfer rules.

Using the Word “Vesting” Without an Implementation Mechanism

The agreement should explain how unvested equity will actually be transferred.

Making the Company the Automatic Buyer

Company buybacks are subject to corporate law restrictions.

Ignoring Share Transfer Formalities

This is particularly dangerous in limited liability companies.

No Good Leaver Protection

A founder dismissed without wrongdoing should not necessarily receive the same treatment as a founder committing fraud.

Excessively Broad Bad Leaver Definition

Almost any disagreement should not automatically lead to punitive forfeiture.

No Valuation Mechanism

The parties may know that shares must be transferred but have no idea at what price.

No Exit Treatment

The agreement fails to explain what happens to vesting during an acquisition.

No Death or Disability Rules

Unexpected personal events may create major ownership uncertainty.

No Coordination With the Articles of Association

Contractual obligations may not produce the intended corporate result.

No Investor Coordination

Founder vesting may conflict with later investment documents.

Founder Vesting Checklist

A startup preparing a founder vesting arrangement should consider:

• founder identities,
• company type,
• shareholding percentages,
• vesting commencement date,
• total vesting period,
• cliff period,
• monthly or quarterly vesting,
• milestone vesting,
• already vested founder contributions,
• Good Leaver definition,
• Bad Leaver definition,
• resignation,
• termination without cause,
• termination for cause,
• death,
• disability,
• vested shares,
• unvested shares,
• purchaser of unvested shares,
• call option mechanism,
• exercise period,
• purchase price,
• valuation procedure,
• share transfer formalities,
• acceleration,
• change of control,
• drag-along,
• tag-along,
• lock-up,
• non-compete,
• confidentiality,
• dispute resolution,
• governing law, and
• corporate implementation.

The agreement should be designed according to the actual startup rather than a standard checklist alone.

When Should Founder Vesting Be Introduced?

Ideally, vesting should be discussed when the startup is formed.

At that stage:

• the company has limited value,
• founders’ interests are generally aligned, and
• difficult scenarios can be discussed objectively.

It becomes harder to negotiate vesting after a dispute begins.

It is also possible to introduce vesting during an investment round, particularly where investors require it as a closing condition.

However, founders usually have greater flexibility if they establish a reasonable structure before investors dictate the terms.

Is Vesting Unfair to Founders?

Properly structured vesting should not be viewed as a punishment.

It protects active founders as much as it protects investors.

Consider two founders who each receive 50%.

Without vesting, each founder takes the risk that the other may leave immediately while retaining half of the startup.

With mutual vesting, both founders are protected.

The mechanism effectively says:

“We will each earn the long-term benefit of our founder equity by continuing to build the company together.”

The fairness of the arrangement depends on:

• vesting period,
• treatment of prior contributions,
• leaver definitions,
• transfer price, and
• circumstances of termination.

Why Founder Vesting Matters During Due Diligence

Professional investors often examine whether founder equity is structured appropriately.

An investor may become concerned where:

• a departed founder owns 30%,
• inactive shareholders cannot be bought out,
• founder shares are entirely unconditional,
• vesting promises exist only in WhatsApp messages,
• the company has no mechanism to recover unvested equity, or
• share transfer documentation is legally defective.

These problems can affect:

• valuation,
• investment terms,
• closing timetable, and
• investor willingness to proceed.

Vesting is therefore not merely an internal founder issue.

It is part of investment readiness.

Conclusion

Founder vesting is one of the most important equity protection mechanisms for a startup.

Its purpose is to prevent a founder from receiving a substantial permanent ownership position without completing the contribution expected from that founder.

For Turkish startups, founder vesting may be structured through mechanisms including:

• reverse vesting,
• contractual share transfer obligations,
• call options,
• Good Leaver and Bad Leaver provisions,
• lock-ups,
• acceleration rights, and
• corporate implementation mechanisms.

However, founders should recognize that “vesting” is a commercial concept that must be translated into legally effective Turkish documentation.

A four-year vesting schedule or one-year cliff written into a contract is not sufficient unless the agreement also establishes what happens legally when a founder leaves.

A properly structured vesting arrangement should answer:

Who retains which shares?

What happens to unvested shares?

Who can purchase them?

At what price?

What happens if the founder is dismissed?

What happens if the company is sold?

What happens if the founder dies or becomes disabled?

How will the transfer be implemented under Turkish corporate law?

These questions become increasingly important as the company grows.

A startup may survive an early product failure and build another product.

It may survive a failed marketing strategy and change direction.

But a badly structured cap table involving large amounts of dead founder equity can become extremely difficult to repair.

For this reason, founders who intend to build a scalable company, raise venture capital or eventually complete an exit should consider vesting as part of the startup’s legal architecture from the beginning.
