How to structure founding team equity
Founding team equity should be structured with 4-year vesting and a 1-year cliff. Co-founders typically receive 10-40% each, with the CEO often having a controlling stake. Early hires receive meaningful equity (0.5-3%) to align incentives with company success.
How you structure equity among your founding team determines who stays, who leaves, and whether you can raise your next round without a civil war. Most founders treat equity as an afterthought — a spreadsheet exercise done the night before signing incorporation documents. That is a mistake that costs millions in legal fees, broken partnerships, and stalled fundraising.
This guide covers the practical mechanics of founding team equity: how much each role should get, how to structure vesting, what acceleration clauses mean, and how to avoid the most common mistakes. It is written for founders who need to make these decisions in the next 30 days, not for lawyers who bill by the hour.
How Much Equity Should Each Role Get?
There is no universal formula, but there are reasonable ranges based on thousands of startups. Here is what typical equity allocations look like at incorporation:
Co-founders: The CEO typically receives 40% to 60% of founder equity, with other co-founders splitting the remainder. A two-founder team often splits 50/50 or 60/40. A three-founder team might split 40/35/25 or 45/30/25. The exact split depends on who came up with the idea, who is full-time versus part-time, who is raising capital, and who has the technical skills to build the product.
Founding engineer: 1.5% to 2.5% fully diluted at pre-seed. This is the highest non-founder allocation because founding engineers take the most technical risk and have the most alternative options. At seed, this drops to 0.75% to 1.5%. At Series A, 0.2% to 0.5%.
Founding designer: 0.5% to 1.5% at pre-seed. If the designer is also doing product or brand strategy, aim for the higher end. At seed, 0.3% to 0.8%. At Series A, 0.1% to 0.3%.
Founding sales or GTM: 0.5% to 1.5% at pre-seed, with higher allocations if the person is building the entire go-to-market function from scratch. At seed, 0.3% to 1.0%. These roles often include commission structures that supplement equity.
First 10 hires: 0.25% to 0.75% depending on seniority and role criticality. By employee 10, you should have established an option pool of 10% to 15% of fully diluted shares.
These numbers assume 4-year vesting with a 1-year cliff. If you offer shorter vesting or no cliff, reduce the grant proportionally.
Vesting Schedules and Cliffs
Vesting is the mechanism by which equity is earned over time rather than granted upfront. It protects the company and aligns incentives. Without vesting, a co-founder who leaves after three months keeps their full equity stake, leaving the remaining founders diluted and resentful.
The standard structure is 4-year vesting with a 1-year cliff. This means no equity vests during the first year. After the first anniversary, 25% vests immediately. The remaining 75% vests monthly or quarterly over the next three years.
Why 4 years? It aligns with the typical startup journey from incorporation to Series B or exit. Most startups take 4 to 7 years to reach a meaningful liquidity event. Four-year vesting keeps founders and early employees engaged through the hardest phase.
Why a 1-year cliff? It filters out people who are not committed. Startups are hard. Some people realize within months that the lifestyle is not for them. A cliff ensures that only people who stay at least a year earn meaningful equity.
What about shorter cliffs? Some startups offer 6-month cliffs for early employees to seem more competitive. This is generally a mistake. It reduces the signal value of vesting and can create misalignment. If you must offer a shorter cliff, reduce the overall grant to compensate.
Acceleration Clauses
Acceleration determines what happens to unvested equity in specific events, typically an acquisition or termination without cause.
Single-trigger acceleration vests all unvested equity upon acquisition. This is founder-friendly but investor-unfriendly. Investors dislike it because it reduces the incentive for founders to stay post-acquisition. Most term sheets prohibit single-trigger acceleration for founders.
Double-trigger acceleration vests unvested equity only if two events occur: an acquisition and a termination without cause within 12 months of the acquisition. This is the market standard. It protects founders if they are fired after a deal closes while keeping them aligned during the transition.
Founding team members below the co-founder level sometimes negotiate for single-trigger acceleration. This is reasonable for early employees who joined at below-market cash and took significant risk.
The Option Pool
The option pool is the reserve of unallocated shares set aside for future employees. Investors typically require an option pool of 10% to 20% of fully diluted shares before investing. If you do not have one, they will make you create one as a condition of the round, diluting existing shareholders.

Frequently Asked Questions
Should I give equal equity to all co-founders?
Rarely. Equal splits feel fair initially but create governance problems. One co-founder needs to be the tie-breaker. The equity split should reflect expected contribution over the next four years, not just who had the idea. Unequal splits are harder conversations now but prevent harder conversations later.
What happens if a co-founder leaves before the cliff?
They forfeit all unvested equity. That is the purpose of the cliff. After the cliff, they keep what has vested and forfeit the rest. The unvested equity returns to the option pool or is redistributed to remaining founders, depending on your agreements.
Can I change the vesting schedule after granting equity?
Only with the employee's consent. Attempting to unilaterally extend vesting is illegal and destroys trust. If you need different terms, negotiate a new grant or a refresh.
How do I handle equity for part-time co-founders?
Part-time co-founders should receive proportionally less equity than full-time co-founders. A common approach is to calculate the full-time equivalent and apply that percentage. A part-time co-founder working 20 hours per week might receive 50% of what a full-time co-founder receives, with the same vesting terms.
What is a reasonable equity refresh for early employees at Series A?
A typical refresh at Series A is 0.1% to 0.3% for strong performers who have been with the company for 18 to 24 months. The refresh should have its own 4-year vesting schedule, sometimes with a shorter cliff or no cliff for trusted employees. Refreshes are critical for retention once initial grants are deep into vesting.
