What Happens When a Startup Founder Leaves the Company in Turkey?

A founder leaving a startup can be one of the most difficult events in the life of a growing company.

Startup founders usually begin their business with shared expectations. They develop the product together, divide the equity, meet investors, hire employees and build the company around a common vision.

However, founder relationships do not always continue indefinitely.

A founder may:

• resign voluntarily,
• stop working for the startup,
• become involved in another business,
• disagree with the other founders,
• be removed from management,
• be dismissed as an employee,
• become unable to continue working,
• breach contractual obligations, or
• simply decide to pursue another career.

When this happens, a critical legal question arises:

What happens to the departing founder’s shares?

The answer is not as simple as many entrepreneurs assume.

Leaving the operational team does not automatically mean losing ownership of company shares. Similarly, removing a founder from the board of directors does not necessarily remove that person from the company as a shareholder.

Under Turkish law, a founder may have several legally distinct positions at the same time.

The founder may be:

• a shareholder,
• a board member,
• a manager,
• an employee,
• a consultant,
• a company representative, or
• an intellectual property owner.

Each of these relationships must be considered separately.

This article explains what may happen when a startup founder leaves a company in Turkey and how founders can structure departure mechanisms before a dispute occurs.

Does a Founder Lose Their Shares When They Leave a Startup?

Not automatically.

This is one of the most important principles founders should understand.

If a founder owns shares in a Turkish company, simply resigning from employment, management or day-to-day operations does not normally cause those shares to disappear.

For example, assume two founders establish a startup:

Founder A: 50%
Founder B: 50%

After eighteen months, Founder B decides to stop working for the company.

Unless there is a legally effective agreement requiring a transfer of some or all of Founder B’s shares, Founder B may continue to own 50% of the company.

This can create serious difficulties.

Founder A may continue working for several years while Founder B remains a passive shareholder entitled to benefit from the future value of the startup.

The possibility of such an outcome is one reason founder vesting and leaver provisions are extremely important.

A Founder Can Have Several Different Legal Roles

Before analyzing what happens when a founder leaves, it is necessary to identify exactly which role is ending.

A startup founder may simultaneously be:

1. a shareholder,
2. a board member,
3. a company manager,
4. an employee,
5. an authorized signatory, and
6. a consultant.

Ending one position does not necessarily terminate the others.

For example:

A founder may resign as CEO but remain a shareholder.

A founder may be removed from the board but retain all shares.

A founder’s employment contract may be terminated while the founder continues to participate in shareholder meetings.

A founder may sell shares but remain temporarily employed by the startup.

Founder departure therefore requires a structured legal analysis.

Shareholder Status

Shareholder status relates to ownership of the company.

A shareholder may have rights such as:

• voting rights,
• dividend rights,
• information rights,
• participation in general assembly meetings,
• rights relating to capital increases, and
• economic rights in an exit transaction.

The precise rights depend on the type of company, share class, articles of association and relevant agreements.

A founder does not cease to be a shareholder merely because the founder no longer works for the startup.

Management Position

Management is separate from share ownership.

In a Turkish joint stock company, management is generally exercised through the board of directors.

In a limited liability company, management is generally exercised by one or more managers.

A founder may therefore lose management authority while continuing to own shares.

This distinction can be strategically important during founder disputes.

Other shareholders may have the ability to change management without necessarily being able to force a transfer of the founder’s shares.

Employment Relationship

A founder may also work for the startup under an employment relationship.

If that employment relationship ends, employment law consequences may arise independently from corporate law issues.

Depending on the circumstances, questions may include:

• salary entitlements,
• notice,
• severance,
• annual leave,
• employment termination,
• confidentiality, and
• post-employment restrictions.

The termination of employment does not automatically terminate share ownership.

Representation Authority

A founder may also have authority to represent and legally bind the company.

For example, the founder may be authorized to:

• sign contracts,
• access company bank accounts,
• execute employment agreements,
• sign payment instructions, or
• represent the company before third parties.

When a founder leaves, representation authority should be reviewed immediately.

Failure to remove outdated signing authority may create serious operational and financial risks.

Why Founder Departure Can Become a Major Startup Problem

The departure of an ordinary employee may be disruptive.

The departure of a founder may affect the entire company.

A departing founder may control:

• a substantial percentage of the shares,
• voting rights,
• board seats,
• source code,
• customer relationships,
• domain names,
• bank access,
• passwords,
• investor relationships, and
• commercially sensitive information.

Founder departures therefore need to address both legal ownership and practical control.

What Is Dead Equity?

Dead equity refers to significant company ownership held by a person who no longer contributes meaningfully to the business.

Consider a startup with the following structure:

Founder A: 50%
Founder B: 50%

Founder B leaves after six months.

Founder A spends another five years building the startup.

The company eventually becomes worth USD 20 million.

If Founder B remains entitled to 50%, a substantial amount of company equity is controlled by an inactive founder.

This can make future fundraising difficult.

An investor may ask:

Why should we invest capital when half of the company belongs to someone who no longer works here?

Founder vesting and share repurchase mechanisms are intended to prevent this situation.

Founder Vesting and Departure

A founder vesting arrangement determines what portion of the founder’s equity remains protected depending on how long the founder continues contributing.

For example, assume a founder owns 40%, subject to four-year reverse vesting.

After two years, approximately half of that vesting package may have become vested.

If the founder leaves, the agreement may allow the founder to retain the vested portion while requiring the transfer of the unvested portion.

The precise implementation must comply with Turkish corporate law.

The concept should not simply be copied from a foreign template.

Reverse Vesting

Reverse vesting is particularly common for startup founders.

Unlike an employee who may gradually receive shares, a founder often owns the shares from the beginning.

However, the agreement may provide that unvested shares become subject to transfer if the founder leaves before the agreed period ends.

The documentation should clarify:

• which shares are vested,
• which shares remain unvested,
• who can acquire the unvested shares,
• the purchase price,
• the exercise period, and
• the applicable share transfer procedure.

Without these details, a vesting provision may create uncertainty rather than solve it.

Good Leaver and Bad Leaver Rules

Founder departure agreements frequently distinguish between Good Leavers and Bad Leavers.

This distinction can materially affect the departing founder’s economic position.

What Is a Good Leaver?

A Good Leaver is generally a founder who leaves under circumstances that are not considered misconduct.

Depending on the agreement, Good Leaver events may include:

• death,
• permanent disability,
• serious illness,
• termination without cause,
• departure by mutual agreement,
• retirement approved by the company, or
• another justified reason.

A Good Leaver may receive relatively favorable treatment regarding shares.

For example:

• vested shares may be retained,
• unvested shares may be transferred,
• transferred shares may be purchased at fair market value, or
• accelerated vesting may apply in certain circumstances.

The precise consequences should be stated in the agreement.

What Is a Bad Leaver?

A Bad Leaver is generally a founder whose departure arises from serious misconduct or contractual breach.

Examples may include:

• fraud,
• embezzlement,
• theft of company property,
• serious confidentiality breach,
• intentional misuse of company IP,
• unlawful competition,
• serious breach of the shareholders’ agreement,
• gross misconduct, or
• other material wrongdoing.

A Bad Leaver may be required to transfer shares under less favorable economic terms.

However, Bad Leaver clauses must be carefully drafted.

An extremely broad clause that treats every voluntary resignation as misconduct may create serious legal and commercial concerns.

Voluntary Resignation

A founder may simply decide to leave.

The agreement should determine whether voluntary resignation constitutes:

• Good Leaver,
• Bad Leaver, or
• a separate category.

The answer may depend on factors such as:

• how long the founder stayed,
• whether the founder gave proper notice,
• whether vesting was completed,
• whether the founder complied with contractual commitments, and
• whether the founder joins a competing business.

A founder who leaves after seven years should not necessarily be treated in the same way as a founder who abandons the company after three months.

Removal Without Cause

A particularly important scenario arises where the other shareholders or board remove a founder even though the founder has not committed misconduct.

Imagine a founder whose shares are still vesting.

The founder is removed from management shortly before a substantial amount of equity is scheduled to vest.

If the agreement provides that all vesting immediately stops regardless of the reason for termination, the other shareholders could theoretically benefit from removing the founder strategically.

For this reason, founders often negotiate protections for termination without cause.

These may include:

• Good Leaver treatment,
• partial accelerated vesting,
• fair market value purchase rights, or
• continued vesting for a limited period.

Removal for Cause

Different rules may apply where a founder is removed because of serious misconduct.

The agreement should clearly define “cause.”

Possible events may include:

• fraud,
• serious breach of fiduciary duties,
• intentional damage to the company,
• unauthorized transfer of confidential information,
• criminal conduct materially affecting the company, or
• serious violation of the shareholders’ agreement.

Vague wording should be avoided.

Statements such as “failure to behave appropriately” can lead to significant disputes.

Can the Other Founders Force a Founder to Sell Shares?

Only where there is an appropriate legal basis.

The fact that other founders no longer want to work with someone does not automatically allow them to take that person’s shares.

A compulsory transfer may require mechanisms such as:

• a contractual call option,
• reverse vesting,
• a Good Leaver/Bad Leaver provision,
• a share transfer obligation,
• a buy-sell mechanism,
• a contractual exit right, or
• another legally valid mechanism.

Mandatory corporate law provisions and the company’s legal form must also be considered.

A shareholder cannot generally be deprived of ownership simply because the relationship between founders has deteriorated.

Call Options

A call option may give another person the right to purchase specified founder shares following a departure event.

The option may belong to:

• another founder,
• existing shareholders,
• an investor,
• a designated third party, or
• in certain legally permissible structures, the company.

The agreement should define:

• triggering events,
• exercise price,
• exercise period,
• number of shares,
• valuation,
• transfer procedure, and
• consequences of non-cooperation.

Call options are commonly used to implement founder leaver arrangements.

Can the Company Buy Back the Founder’s Shares?

Potentially, but company acquisitions of their own shares are subject to statutory limitations.

The legal rules depend on whether the startup is structured as:

• an Anonim Şirket, or
• a Limited Şirket.

Therefore, a foreign template stating that “the company shall automatically repurchase all founder shares” may not operate as intended in Turkey.

The buyback structure should be examined before the agreement is signed.

In some cases, giving the purchase right to existing shareholders may provide a more practical mechanism.

Founder Departure in a Joint Stock Company

For venture-backed startups, the company will frequently be structured as an Anonim Şirket (A.Ş.).

Founder departure may require consideration of:

• board membership,
• share ownership,
• share certificates,
• share ledger records,
• transfer restrictions,
• articles of association,
• shareholder agreements,
• representation authority, and
• investment rights.

If the founder is a board member, a separate corporate process may be necessary to change the board.

The founder’s board position and share ownership should be analyzed separately.

Founder Departure in a Limited Liability Company

Founder departure from a Limited Şirket may involve additional formalities concerning share transfers.

Transfer of a limited liability company interest is generally subject to specific formal requirements.

Depending on the articles of association and circumstances, shareholder approval may also be relevant.

A founder departure agreement should therefore not assume that ownership changes automatically after a resignation letter.

Proper share transfer procedures must be completed.

Can a Founder Be Expelled From a Limited Liability Company?

Turkish corporate law provides mechanisms relating to the removal or withdrawal of shareholders from limited liability companies under certain circumstances.

However, this is different from a contractual startup vesting mechanism.

The availability of removal may depend on:

• provisions in the articles of association,
• justified reasons,
• court proceedings, or
• other statutory requirements.

It should not be assumed that any commercial disagreement allows the majority shareholders to expel a founder immediately.

Intellectual Property After a Founder Leaves

One of the most critical departure issues is ownership of intellectual property.

Startup IP may include:

• source code,
• software,
• algorithms,
• trademarks,
• designs,
• patents,
• databases,
• documentation,
• trade secrets, and
• domain names.

Before a founder leaves, the company should determine whether the startup legally owns the IP it uses.

This is particularly important where the founder developed the technology before incorporation.

Software Created Before the Company Was Established

Many technology startups begin before formal incorporation.

For example, the technical founder may develop the first version of the software personally.

The company may later be incorporated.

If no appropriate transfer or licensing arrangement is executed, questions may arise concerning ownership of the pre-incorporation software.

A departing founder may then argue that certain technology belongs personally to them.

This can threaten:

• product continuity,
• investment rounds,
• customer contracts, and
• company valuation.

Intellectual property ownership should therefore be documented before any dispute arises.

Source Code Access

Legal ownership alone is not enough.

The company must also have practical access.

When a technical founder leaves, the startup should ensure control over:

• GitHub or other repositories,
• hosting services,
• databases,
• API credentials,
• cloud services,
• deployment systems,
• application store accounts,
• security certificates, and
• technical documentation.

Critical infrastructure should never depend entirely on one founder’s personal account.

Domain Names

A common startup mistake is registering the company’s domain name personally in the founder’s name.

If that founder later leaves, ownership may become disputed.

The company should ideally control:

• domain registrations,
• DNS services,
• hosting,
• email infrastructure, and
• related administrator accounts.

These assets should be included in the founder departure checklist.

Trademark Ownership

The same issue applies to trademarks.

A founder may have registered the startup’s brand personally before the company existed.

Before or during incorporation, the necessary rights should be transferred or licensed appropriately.

An investor acquiring 20% of a startup will usually expect the company itself to control the brand.

A founder departure should not create uncertainty concerning trademark ownership.

Confidential Information

A departing founder may possess significant confidential information.

Examples include:

• customer lists,
• product strategy,
• pricing,
• investor negotiations,
• financial data,
• algorithms,
• source code,
• business plans, and
• trade secrets.

The Founders’ Agreement or Shareholders’ Agreement should contain confidentiality provisions that survive departure.

The company should also implement practical measures such as:

• closing accounts,
• changing passwords,
• revoking access rights,
• collecting devices,
• removing repository access, and
• securing confidential files.

Can a Departing Founder Compete With the Startup?

This depends on the circumstances and contractual framework.

Startup agreements frequently contain non-compete provisions.

However, restrictions on competition cannot be unlimited.

Factors that may become relevant include:

• duration,
• geographic scope,
• industry,
• legitimate commercial interests, and
• proportionality.

A clause prohibiting a founder from working in any technology business anywhere in the world for ten years would raise obvious enforceability concerns.

The restriction should be designed to protect legitimate startup interests without becoming unnecessarily broad.

Non-Solicitation

A founder may leave without directly launching a competing company but still attempt to recruit:

• key developers,
• employees,
• customers,
• suppliers, or
• strategic partners.

A non-solicitation clause may restrict this behavior for a defined period.

Such restrictions should also be proportionate and clearly drafted.

Company Property

A departing founder should return all company property.

This may include:

• laptops,
• phones,
• credit cards,
• access devices,
• corporate records,
• source code copies,
• storage devices,
• customer documents,
• technical equipment, and
• confidential materials.

A formal departure process should document the return of these items.

Bank Access

Banking authority should be reviewed immediately.

If the founder has access to:

• corporate bank accounts,
• online banking,
• payment systems,
• corporate credit cards, or
• cryptocurrency wallets,

those permissions may need to be revoked or restructured.

Leaving a former founder with financial access can expose the startup to significant risk.

Corporate Signing Authority

Trade registry and company representation records should also be reviewed.

If the founder was registered as an authorized representative, it may be necessary to complete the appropriate corporate and registry procedures.

Internal removal of authority may not be sufficient if third parties can still rely on registered representation powers.

Customer Relationships

Some founders personally manage major customers.

When that founder leaves, the startup should ensure a structured handover.

This may involve:

• introduction of a new account manager,
• transfer of contract history,
• transfer of correspondence,
• confirmation of company ownership of customer information, and
• communication regarding the founder’s departure.

A founder should not be able to take company customers merely because the founder originally introduced them.

Investor Relationships

A founder may also have been primarily responsible for investor relations.

Investors should generally be informed appropriately if the departure is material to the company.

This becomes particularly important where investment documents contain:

• key person clauses,
• founder commitment provisions,
• information obligations, or
• investor consent rights.

A founder departure may even trigger contractual rights under an investment agreement.

Key Person Clauses

Venture capital agreements sometimes include key person protections.

An investor may consider a particular founder essential to the investment.

If that founder stops working for the company, the agreement may:

• require investor notification,
• restrict certain activities,
• suspend additional funding,
• trigger board review, or
• require replacement arrangements.

Founders should therefore examine the investment documents before implementing a departure.

Founder Departure Before an Investment Round

If a founder leaves shortly before fundraising, the startup should resolve the share position before approaching serious investors.

Investors may be reluctant to invest where:

• inactive founders own large percentages,
• the company has unresolved shareholder disputes,
• vesting arrangements are unclear,
• IP ownership is disputed, or
• departed founders retain veto rights.

These problems may reduce company valuation or prevent closing.

Founder Departure During an Investment Round

A founder leaving during fundraising may be even more disruptive.

The investor may reconsider:

• valuation,
• investment amount,
• management structure,
• founder vesting,
• board composition, or
• whether to proceed at all.

Investment documents commonly require the founders to confirm that no material adverse change has occurred before closing.

The departure of a critical CTO or CEO may be considered commercially significant.

Founder Departure After Investment

After institutional investment, founder departure will usually be governed by more detailed documentation.

The Shareholders’ Agreement may contain:

• vesting,
• Good Leaver rules,
• Bad Leaver rules,
• board replacement procedures,
• share transfer mechanisms,
• call options,
• confidentiality obligations, and
• investor approval rights.

At this stage, the founder may no longer be able to negotiate departure conditions freely because the relevant consequences may already be contractually determined.

What Happens to Vested Shares?

The answer depends on the agreement.

Possible structures include:

• the founder keeps all vested shares,
• other shareholders have a purchase option,
• vested shares are purchased at fair market value,
• the founder may remain as a passive shareholder, or
• vested shares become subject to a sale mechanism after certain events.

There is no universal rule that vested shares must always remain with the founder.

The contract must be reviewed carefully.

What Happens to Unvested Shares?

Unvested shares are commonly treated differently.

Depending on the structure, they may become subject to:

• mandatory transfer,
• a call option,
• repurchase rights,
• transfer at original acquisition cost, or
• another contractual mechanism.

The legal implementation must comply with the company’s share transfer rules.

Share Valuation

If founder shares must be transferred, one of the biggest questions is price.

Possible valuation methods include:

• nominal value,
• original acquisition price,
• latest investment valuation,
• fair market value,
• independent expert valuation,
• revenue multiple,
• EBITDA multiple, or
• a predetermined contractual formula.

Good Leaver and Bad Leaver shares may be priced differently.

The agreement should define the methodology before a dispute arises.

Fair Market Value

Fair market value can be particularly difficult to determine for startups.

An early-stage startup may:

• have no profits,
• have limited revenue,
• own valuable technology,
• have completed an investment round recently, or
• be negotiating a major contract.

Traditional accounting value may therefore significantly underestimate the company’s economic value.

An independent valuation mechanism may provide greater protection.

Founder Loans

A founder may also have lent money to the company.

Leaving the startup does not automatically cancel those loans.

The parties should separately determine:

• outstanding loan principal,
• interest,
• repayment schedule,
• subordination,
• conversion rights, and
• whether the loan is linked to the founder’s equity position.

Share ownership and shareholder loans are legally distinct issues.

Unpaid Founder Expenses

Founders frequently pay company expenses personally.

A departure process should identify whether the company owes the founder reimbursement for:

• travel,
• software,
• office expenses,
• marketing,
• equipment, or
• other approved business costs.

These amounts should be documented separately from the purchase price for shares.

Founder Salary and Employment Claims

Where the founder is also an employee, employment-related claims may need to be considered separately.

Possible claims may concern:

• salary,
• unused annual leave,
• employment termination,
• notice rights,
• severance rights where applicable, and
• other employment receivables.

Corporate documents should not assume that transfer of shares settles all employment claims unless the relevant issues are lawfully resolved.

Shareholder Information Rights After Departure

If the founder remains a shareholder, certain shareholder rights may continue.

This can create a difficult situation.

A former founder who now competes with the company may potentially remain entitled to certain corporate information as a shareholder, subject to the applicable legal framework.

The company should therefore carefully analyze:

• statutory shareholder rights,
• confidentiality obligations,
• trade secret protections, and
• contractual information rights.

Voting Rights

A departing founder who retains shares may also retain voting rights.

For example:

Founder A: 55%
Departed Founder B: 45%

Founder B may no longer work in the company but may continue participating in shareholder decisions.

This can create governance tension.

Founder agreements should therefore address the relationship between departure and long-term ownership.

Board Seat After Departure

The founder’s departure from employment does not necessarily terminate a board seat automatically.

The relevant corporate procedure may need to be followed.

The Shareholders’ Agreement may also provide that a founder loses the contractual right to nominate a board member if:

• the founder ceases employment,
• ownership falls below a specified percentage, or
• a Bad Leaver event occurs.

These provisions should be coordinated with the articles of association.

Founder Deadlock

Founder departure often occurs after a period of serious disagreement.

If the founders each hold 50%, the company may already be in deadlock.

Possible mechanisms include:

• mediation,
• negotiated buyout,
• share purchase,
• third-party sale,
• Russian roulette mechanism,
• Texas shoot-out mechanism,
• arbitration, or
• court proceedings where appropriate.

Deadlock provisions should ideally be agreed before the founders fall out.

Russian Roulette Clauses

Under a simplified Russian roulette mechanism, one shareholder may offer to buy the other shareholder’s shares at a specified price.

The recipient must then either:

• sell at that price, or
• buy the offeror’s shares at the same valuation.

This mechanism creates an incentive to offer a fair price.

However, it may disadvantage a shareholder with fewer financial resources.

Its appropriateness should therefore be evaluated carefully.

Texas Shoot-Out Mechanisms

A Texas shoot-out may involve both shareholders submitting purchase offers.

The shareholder offering the higher price purchases the other’s shares.

Again, this mechanism may solve deadlock but can favor the financially stronger party.

It should not be adopted automatically.

Mediation

A founder dispute does not always require immediate litigation.

Mediation may help resolve issues such as:

• departure terms,
• share valuation,
• IP handover,
• non-compete scope,
• board resignation, and
• payment schedules.

A negotiated departure may preserve significantly more company value than years of shareholder litigation.

Arbitration

Startup Shareholders’ Agreements may contain arbitration clauses.

Arbitration can be useful for disputes involving:

• international founders,
• foreign investors,
• confidential commercial information, or
• high-value share disputes.

However, the dispute resolution clause should be drafted carefully.

Certain company law disputes may raise specific issues regarding the scope and effect of arbitration.

Exit Transactions After a Founder Leaves

A departing founder who retains shares may later participate in an exit.

Suppose a founder leaves when the company is worth USD 2 million.

Five years later, the startup is sold for USD 100 million.

If the founder legally retained 10%, that founder may potentially participate in the exit based on those shares.

This illustrates why founder departure terms can have enormous long-term economic consequences.

Drag-Along Rights

A departed founder who remains a shareholder should not necessarily be able to block a company sale.

Drag-along rights can require minority shareholders to participate in an approved exit.

For example:

Active shareholders and investors holding 85% approve a sale.

The departed founder owns 15% and refuses.

A properly structured drag-along clause may require participation in the transaction.

Tag-Along Rights

A departed founder who remains a minority shareholder may also benefit from tag-along rights.

If the controlling shareholders sell to a new buyer, the former founder may be entitled to participate in that sale according to the agreement.

Founder departure therefore does not necessarily terminate all investor-style shareholder protections.

Death of a Founder

Founder departure may also occur because of death.

This creates additional legal issues involving inheritance.

Questions may include:

• who inherits the founder’s shares,
• whether transfer restrictions apply,
• whether other shareholders have purchase rights,
• what happens to unvested shares,
• how the shares are valued, and
• whether voting rights pass to heirs.

Founders should consider these issues before they become urgent.

Incapacity

A founder may remain alive but become permanently unable to participate due to incapacity.

The agreements should define:

• what constitutes permanent incapacity,
• how it is determined,
• whether it is a Good Leaver event,
• whether vesting accelerates, and
• what happens to management authority.

Objective procedures can prevent disputes.

Founder Divorce and Shares

Founder shares may also be affected indirectly by matrimonial property issues depending on the founder’s personal circumstances.

Investors sometimes consider risks relating to:

• marital property claims,
• inheritance,
• family transfers, and
• enforcement against founder shares.

Startup documents may therefore contain restrictions governing transfers resulting from personal circumstances, subject to applicable mandatory law.

Enforcement Against Founder Shares

A founder’s creditors may potentially affect company shares through enforcement proceedings.

This is another reason founders and investors should understand the legal status of shares independently from employment or management roles.

A startup’s Shareholders’ Agreement cannot always eliminate rights arising under mandatory enforcement law.

Founder Departure Checklist

When a founder leaves a Turkish startup, the company should consider at least the following issues:

• shareholder status,
• vested shares,
• unvested shares,
• Good Leaver or Bad Leaver classification,
• share transfer rights,
• share valuation,
• board position,
• manager position,
• representation authority,
• employment relationship,
• consulting relationship,
• founder loans,
• unpaid expenses,
• intellectual property,
• source code,
• domain names,
• trademarks,
• cloud accounts,
• passwords,
• bank access,
• corporate cards,
• company devices,
• customer relationships,
• investor communications,
• confidentiality,
• non-compete obligations,
• non-solicitation,
• trade secrets,
• company records,
• pending investment transactions,
• corporate resolutions,
• trade registry filings, and
• future exit rights.

The exact process depends on the founder’s legal roles and the company structure.

Common Mistakes When a Founder Leaves

Assuming Resignation Cancels the Founder’s Shares

It does not automatically do so.

Removing the Founder From Management but Ignoring Share Ownership

Management and ownership are legally separate.

Having No Vesting Agreement

An early departing founder may retain substantial equity.

Using an Unclear Bad Leaver Clause

Ambiguous clauses can produce further disputes.

Forgetting IP Ownership

The departing founder may control important technology.

Leaving Digital Access Open

Repository, banking and cloud access should be reviewed immediately.

No Share Valuation Formula

The parties may agree that shares should be transferred but disagree completely about price.

Ignoring Investment Agreements

The departure may trigger investor rights.

Forgetting Trade Registry Procedures

Internal decisions may require formal registration or announcement.

Trying to Solve Everything With One Resignation Letter

Founder departure may involve several independent legal relationships.

How Startups Can Prepare Before a Founder Leaves

The best founder departure process begins before anyone decides to leave.

Startups should consider establishing:

• Founders’ Agreements,
• Shareholders’ Agreements,
• vesting mechanisms,
• Good Leaver/Bad Leaver rules,
• call options,
• share transfer restrictions,
• IP assignment agreements,
• confidentiality provisions,
• non-solicitation clauses,
• deadlock mechanisms, and
• clear corporate governance rules.

The startup should also avoid dependence on founders’ personal accounts.

All essential company assets should be under institutional control.

Why Investors Care About Founder Departure Rules

Investors are extremely sensitive to founder continuity.

They may ask during due diligence:

• Are founders subject to vesting?
• Can a founder leave while keeping all shares?
• Are there inactive shareholders?
• Can founder shares be transferred?
• Who owns the IP?
• What happens if the CTO leaves?
• Are founders subject to confidentiality?
• Can departed founders compete?
• Does the company have control of its source code?

Weak answers can affect valuation and investment terms.

Legal Due Diligence After a Founder Departure

Before a future investment, the company should ensure that the departing founder’s position is fully documented.

An investor may request:

• resignation documents,
• board resolutions,
• share transfer agreements,
• updated cap table,
• IP assignments,
• settlement agreements,
• employment termination documents,
• confirmation of access termination, and
• updated trade registry records.

An unresolved founder departure is often considered a significant due diligence red flag.

Settlement Agreements With Departing Founders

A negotiated settlement agreement may provide an effective method of resolving multiple issues at once.

Depending on the case, it may address:

• resignation,
• share ownership,
• share transfer,
• purchase price,
• payment schedule,
• IP confirmation,
• confidentiality,
• non-disparagement,
• return of property,
• employment claims,
• founder loans,
• mutual releases, and
• dispute resolution.

However, the agreement must be coordinated with mandatory corporate and employment law rules.

A contractual settlement cannot replace corporate procedures that are legally required for a share transfer or board change.

Practical Example

Consider a Turkish technology startup established by three founders.

Founder A: 45%
Founder B: 35%
Founder C: 20%

All founders are subject to four-year reverse vesting.

After eighteen months, Founder C decides to leave voluntarily.

The agreement provides that:

• vested shares remain with Founder C,
• unvested shares are subject to a call option,
• Founder C resigns from the board,
• representation authority is removed,
• all company equipment is returned,
• all IP remains with the company,
• confidentiality continues after departure,
• company system access is terminated, and
• Founder C remains subject to agreed transfer restrictions for retained shares.

Because the departure mechanism was documented from the beginning, the company can continue operating with limited disruption.

Without such provisions, Founder C could potentially have retained the full 20% while disputes continued regarding technology, management and access rights.

Conclusion

When a startup founder leaves a company in Turkey, the consequences extend far beyond a simple resignation.

The departing founder may have several legally independent relationships with the startup.

The founder may simultaneously be:

• a shareholder,
• board member,
• manager,
• employee,
• authorized representative,
• lender, and
• creator of important intellectual property.

Each position must be addressed separately.

Most importantly, founders should understand that leaving the startup does not automatically mean losing company shares.

If the founders want equity ownership to depend on continued contribution, they should establish a legally effective structure in advance.

This may include:

• founder vesting,
• reverse vesting,
• Good Leaver and Bad Leaver provisions,
• call options,
• share transfer obligations,
• lock-ups,
• deadlock mechanisms, and
• exit rights.

The startup should also protect its operational assets by ensuring that the company controls its:

• source code,
• intellectual property,
• domains,
• bank accounts,
• cloud infrastructure,
• passwords,
• customer records, and
• confidential information.

A founder departure that is properly planned may be difficult but manageable.

An unplanned founder departure can produce years of shareholder disputes and may ultimately prevent investment or an exit.

For this reason, founders should not wait until someone decides to leave before discussing departure.

The rules should be established while everyone still intends to stay.
