The Questions to Ask Before You Agree to Your Option Pool Size

I spent forty minutes on a call arguing our option pool down from 20% to 13%. I was proud of that number right up until three months later, when I found out the pool was structured to refresh automatically at every future round without needing my consent, a detail nobody put in front of me to negotiate because I never thought to ask.

The percentage isn't the only thing you're agreeing to

When a term sheet lands with an option pool number attached, founders zero in on the percentage. Is it 10, 15, or 20? That number decides how much you're diluted today, so it's the obvious thing to fight over. But the pool isn't just a number. It's a bundle of terms that decide who controls it after it exists, how it gets replenished at your next round, and how much say you keep once the ink is dry. Negotiate the percentage down and skip the mechanics, and you can end up with a smaller number that behaves like a bigger one.

Seven questions to ask before you sign

These rarely show up as a checklist anywhere in the term sheet process. Your lawyer might raise one or two if you ask; your investor will almost never bring them up first, because the default language usually favors them. Ask all seven before you sign, not after.

1. Is the pool created pre-money or post-money? Pre-money means the dilution comes entirely out of your side of the cap table before the investor's ownership is calculated. Post-money splits that cost with the incoming investor. This single word in the term sheet is worth several percentage points of founder equity.
2. Does the pool size match a named hiring plan, or is it a round number the investor opened with? A pool built from actual roles, levels, and grant sizes is defensible and often smaller than the anchor number a fund quotes by habit. If nobody can show you the math behind the percentage, that's your first sign to push back.
3. Who approves grants once the pool exists, the board, the CEO, or a comp committee? This determines whether you can move quickly on a hire you need urgently, or whether every grant becomes a board-calendar problem.
4. What happens to unallocated shares left in the pool at your next round? Some term sheets treat leftover pool as absorbed into the new valuation; others treat any top-up as fresh dilution split however the new round dictates. The difference compounds every time you raise.
5. Does refreshing or topping up the pool at a future round require your consent, or is it pre-authorized in this term sheet? Some standard templates grant the board standing authority to expand the pool at a future closing without a separate founder negotiation. That clause is easy to miss and expensive to discover later.
6. What vesting schedule and cliff is assumed in the sizing math? A pool sized against a standard four-year vest with a one-year cliff behaves very differently from one modeled on faster vesting for senior hires. If the assumption is never stated, the sizing number is closer to a guess than a plan.
7. Does the pool cover advisor and consultant grants, or is that carved out separately? Advisor equity has a habit of quietly eating into a pool sized only with employees in mind, which is often the first thing that makes a seemingly generous pool feel tight within a year.

Why these answers matter more than the headline number

Run the comparison forward. A 12% pool with automatic refresh rights baked in, board-only grant approval, and no founder consent required on top-ups can cost more equity over three funding rounds than a 15% pool that requires a fresh negotiation and your sign-off every time it's touched. The headline percentage is the number everyone remembers from the term sheet. The mechanics are the number nobody notices until it shows up on a cap table two years later.

Who to ask, and when

Ask your lawyer to specifically red-line the mechanics language, not just confirm the percentage is reasonable. Ask your investor the control questions directly, in the same conversation where you're negotiating size, since these are far easier to move before a term sheet is signed than after. Don't wait for your cap table software to surface the answer after the round closes. By then the terms are fixed, and you're just watching them play out.

Frequently asked questions

Can I ask these questions after I've already signed the term sheet?

You can ask, but you'll mostly be documenting terms rather than negotiating them. Pool mechanics are far more movable before signing than after. If you've already signed, the more useful move is understanding exactly what you agreed to so it doesn't surprise you at the next round.

Should my lawyer or my investor answer these questions?

Both, for different reasons. Your lawyer should confirm what the term sheet language actually says and red-line anything ambiguous. Your investor should tell you their intent directly, since term sheet language and a fund's actual practice don't always match, and it's worth hearing both.

Does a smaller headline percentage always mean less dilution?

No. A smaller pool with unfavorable mechanics, like automatic post-money refreshes without founder consent, can cost more over multiple rounds than a larger pool with founder-friendly terms. The percentage is a starting point, not the full picture.

What's the single most important question on this list?

Whether the pool is created pre-money or post-money. It's the one term that most directly decides who bears the cost of the pool today, and it's also the easiest one for a term sheet to leave implicit if you don't ask.

Before your next term sheet lands, print this list and check off every question next to it, not just the percentage box. The number you negotiate is only half of what you're actually agreeing to.
