Founder Vesting: A Practical Guide
When a company is formed, it is common for the founders to divide the shareholding equally from day one. At the outset, this often feels fair. However, businesses evolve. One founder may leave after a few months, change direction or simply be unable to contribute to the business in the way everyone originally expected. If that founder retains a significant equity stake despite no longer contributing, it can create challenges for both the company and the founders who continue to build the business.
This is why founder vesting has become standard practice in many startups and high-growth businesses. By linking equity ownership to long-term commitment, vesting creates a more sustainable ownership structure and significantly reduces the risk of disputes as the company grows.
What Is Founder Vesting?
Founder vesting is a mechanism under which a founder earns the right to retain their shares over a defined period of time.
Although the shares are usually issued to the founder at the outset, the founders agree that, if one of them leaves the business before the vesting period has ended, the company or the remaining shareholders will have the right to repurchase some or all of the shares that have not yet vested.
The purpose is to ensure that ownership reflects each founder’s actual contribution to the business over time. Vesting is therefore not about restricting founders’ rights. Rather, it is about creating an ownership structure that remains fair as the company develops.
Why Is Vesting Important?
No one knows exactly how a startup will develop.
Roles evolve, priorities change and unforeseen circumstances arise. A founder who was expected to play a central role may leave much earlier than anticipated, while others continue investing years of work into growing the company.
Without vesting, the departing founder may retain a substantial shareholding despite no longer contributing to the business. This can become a source of frustration for the remaining founders and may complicate future decision-making.
Vesting addresses this issue by ensuring that equity is earned progressively rather than granted outright from day one. It also aligns the founders’ incentives by encouraging long-term commitment to the business.
For many investors, vesting is no longer simply desirable; it is expected. Angel investors and venture capital funds generally want to ensure that the individuals responsible for creating value remain committed after the investment has been made. A company with a well-structured vesting arrangement is therefore often viewed as better governed and more investment-ready.
When Should Vesting Be Introduced?
The ideal time to implement vesting is when the company is formed or before the founders receive their shares.
At this stage, everyone is usually working towards the same objective and discussions about ownership tend to be more straightforward.
Attempting to introduce vesting several years later is considerably more difficult. By then, the company may have increased significantly in value and the founders may have very different views on what constitutes a fair allocation of equity.
As with many legal issues in startups, planning early is almost always easier than attempting to restructure ownership once the business has become successful.
How Does Founder Vesting Work?
The most common structure consists of a vesting period combined with a cliff.
Vesting Period
A four-year vesting period is widely regarded as the market standard, although the founders are free to agree on any period that suits their circumstances.
During this time, ownership rights are earned progressively rather than immediately.
Cliff
Most vesting arrangements include a one-year cliff.
This means that no shares vest during the first twelve months. If a founder leaves before the first anniversary, they will generally forfeit all unvested shares.
Once the cliff has been reached, approximately 25% of the shares typically vest immediately, with the remaining shares vesting monthly or quarterly over the rest of the vesting period.
For example, a founder holding 20% of the company under a four-year vesting schedule with a one-year cliff would usually vest 5% after the first year, with the remaining 15% vesting gradually over the following three years.
How Does Vesting Work Under Swedish Law?
A common misconception is that founders automatically lose their shares if they leave the company.
That is not how Swedish law operates.
Instead, founder vesting is implemented contractually.
The founder generally owns the shares from the outset. However, under the shareholders’ agreement or a separate share transfer agreement, the company or the remaining shareholders are granted contractual rights to repurchase shares that have not yet vested if the founder ceases to be involved in the business.
It is therefore essential that the relevant agreements clearly specify who may exercise the repurchase right, how the process will operate and how the repurchase price will be determined.
Good Leaver and Bad Leaver Provisions
Many shareholders’ agreements distinguish between different reasons for a founder’s departure.
A Good Leaver is typically someone who leaves for legitimate reasons, such as long-term illness, retirement or termination without fault. In these circumstances, the founder will generally retain the shares that have already vested.
A Bad Leaver, by contrast, may be someone who resigns shortly after the company is established, seriously breaches their obligations or competes with the business.
Depending on the agreement, a Bad Leaver may be required to transfer not only unvested shares but, in some circumstances, part of their vested shareholding, potentially at a price below market value.
Given the potentially significant financial consequences, these provisions should always be drafted carefully and with clear definitions.
What Happens If There Is No Vesting?
Consider two founders who each own 50% of a startup.
After six months, one founder leaves while the other continues building the business full-time for several years.
Without a vesting arrangement, the departing founder continues to own half the company despite making no further contribution. This can become problematic when the business seeks external investment, recruits senior employees or is eventually sold.
A properly drafted vesting arrangement would instead allow the unvested shares to be repurchased and redistributed, ensuring that ownership remains aligned with the individuals actively creating value within the business.
How Is Vesting Documented?
Founder vesting is usually implemented through a shareholders’ agreement, often supported by separate share transfer arrangements or contractual buy-back provisions.
The documentation should clearly address matters such as the length of the vesting period, the existence of a cliff, the consequences of a founder leaving the company, the valuation mechanism for any repurchase and the distinction between Good Leaver and Bad Leaver scenarios.
The more clearly these issues are addressed at the outset, the less likely the founders are to face costly disputes in the future.
Common Mistakes
One of the most common mistakes is deciding not to implement vesting because the founders trust one another.
That trust is entirely understandable. However, founder disputes rarely arise during the company’s first few months. They tend to emerge years later, once the business has become valuable and the commercial stakes are considerably higher.
Another frequent mistake is introducing vesting only after a founder has already indicated an intention to leave. By that stage, negotiating new ownership arrangements is often significantly more difficult.
Similarly, poorly drafted repurchase provisions or vague Good Leaver and Bad Leaver definitions frequently become sources of disagreement precisely when the company is under the greatest commercial pressure.
Is Founder Vesting Always Necessary?
Not necessarily.
Where a sole founder owns the entire company, vesting between founders is generally unnecessary.
However, where two or more founders are involved, vesting has become standard market practice, particularly for businesses intending to raise external investment or pursue rapid growth.
For many investors, the absence of founder vesting is now regarded as a governance issue that should be addressed before completing an investment.
Conclusion
Founder vesting is one of the most effective ways of aligning equity ownership with long-term commitment.
By allowing founders to earn their equity over time, vesting reduces the likelihood that someone who leaves early retains a disproportionate ownership interest. It also creates a stronger foundation for future investment, recruitment and long-term growth.
For companies with multiple founders, vesting is no longer simply a legal technicality. It is an important component of sound corporate governance and a feature that investors increasingly expect to see.
