How Big an Option Pool Will Investors Make Me Add Before My Round Closes?
Your lead investor sends over a term sheet. The valuation looks exactly as you hoped. Then you notice another provision.
Before the financing closes, the investor wants the company to increase its employee option pool.
At first, it seems like a routine request. After all, every growing startup needs equity to hire future employees.
What many founders don’t realize is that when the option pool is created can be just as important as how large it is. A pre-money option pool can significantly increase founder dilution without changing the headline valuation shown in the term sheet.
Why Investors Ask for a Larger Option Pool
Investors want startups to have enough equity available to recruit future employees without needing another shareholder approval immediately after the financing.
A healthy option pool helps attract engineers, executives, and other key hires as the business grows.
The discussion usually isn’t about whether an option pool should exist.
Instead, negotiations focus on its size and whether it is created before or after the investment closes.
A Pre-Money Option Pool Primarily Dilutes Founders
Most venture financing rounds require the option pool to be expanded before the new investment is made.
This is known as a pre-money option pool.
Because the additional shares are created before investors purchase their preferred stock, the resulting dilution is generally borne by the existing shareholders rather than the new investors.
This concept is often referred to as the option pool shuffle, and it is one of the most frequently misunderstood provisions in a venture financing.
The Headline Valuation Doesn’t Tell the Whole Story
Many founders negotiate intensely over valuation while paying less attention to the option pool.
However, increasing the number of outstanding shares before the financing changes the price per share used in the transaction.
The result is that the company’s effective pre-money valuation may be lower than the headline valuation presented in the term sheet.
Although the stated valuation remains unchanged, founders often own a smaller percentage of the company after closing because of the larger pre-money option pool.
How Large Should the Option Pool Be?
There is no universal answer.
Investors commonly request 15% to 20% post-money option pools, while many startups’ actual hiring needs for the next 12 to 18 months are closer to 8% to 12%.
A pool that is significantly larger than the company’s expected hiring requirements may leave a substantial number of unissued shares sitting idle while unnecessarily diluting the founders.
The goal should be to size the pool based on realistic hiring plans rather than relying on standard percentages alone.
Support Your Negotiation With a Hiring Plan
Founders are often in a stronger negotiating position when they can explain exactly why a particular option pool size is appropriate.
Instead of negotiating based on general expectations, prepare a detailed hiring plan covering the next 12 to 18 months.
This plan should identify:
- Key roles the company expects to hire.
- Estimated equity grants for each position.
- The total number of shares needed to support those hires.
A data-driven approach often makes it easier to justify a smaller option pool that still supports the company’s growth objectives.
Model the Dilution Before Signing
Before agreeing to any option pool increase, founders should update their capitalization model.
The analysis should reflect:
- The new option pool.
- The incoming investment.
- Any SAFE or convertible note conversions.
- Founder ownership after closing.
Reviewing the complete post-financing ownership picture provides a much better understanding of how the option pool affects both dilution and the company’s effective valuation.
Common Founder Mistakes
- Negotiating only the headline valuation: A strong valuation can still produce significant founder dilution if the option pool is expanded on a pre-money basis before the financing closes.
- Accepting the investor’s requested option pool without reviewing future hiring needs: A pool should reflect realistic hiring plans rather than an arbitrary percentage that leaves unnecessary equity unused.
- Failing to understand the difference between pre-money and post-money option pools: The timing of the pool expansion determines who bears the dilution and can materially affect founder ownership.
- Negotiating without a detailed hiring plan: A role-by-role hiring forecast for the next 12 to 18 months provides a much stronger basis for discussing the appropriate option pool size.
10-Minute Option Pool Self Check
- Is the proposed option pool being created before or after the financing closes?
- Have I calculated how the new pool affects my ownership percentage?
- Does the requested pool match my actual hiring plan for the next 12 to 18 months?
- Have I modeled the effective pre-money valuation after the option pool is added?
- Have I compared different option pool sizes before negotiating?
- Can I justify my proposed pool size with a documented hiring plan?
If several answers remain unclear, you are not ready to respond to this term sheet yet..
Bottom Line
The size and timing of an employee option pool can have a significant impact on founder ownership, even when the headline valuation remains unchanged. Understanding how pre-money option pools affect dilution, building a realistic hiring plan, and modeling the post-financing cap table before signing a term sheet allows founders to negotiate from a much stronger position.
