Option Pool: How to Size It and Avoid the Pre-Money Trap

Option Pool: Sizing, Timing, and the Pre-Money Shuffle

The option pool is the pool of shares reserved for future employee equity grants. Every priced round negotiates its size — and where it sits in the cap table. Founders who don't understand the pre-money option pool shuffle systematically over-dilute.

The pre-money option pool shuffle

Investors typically require the option pool be created (or topped up) in the pre-money — meaning the dilution comes entirely from founders and existing shareholders, not the new investors. On a $10M pre-money round with a 15% post-money option pool, founders effectively see valuation of ~$8.5M for dilution purposes.

How to size honestly

Build a hiring plan for the next 18-24 months. For each planned hire, apply market equity ranges (VP: 0.5-1.5%, Director: 0.15-0.4%, Senior IC: 0.1-0.25%, IC: 0.05-0.15%). Sum the total. That's your honest pool need — usually 8-12% at seed, 10-15% at Series A. Investors will push higher; push back with the hiring plan.

Timing: top-up vs. new pool

Every priced round creates or tops up the pool. Founders should minimize top-ups by using the pool efficiently between rounds (don't over-grant early). Top-ups requested by new investors dilute existing shareholders — including previous investors, who often push back with founders.

Alternative structures

Post-money option pool: dilution is shared across all shareholders including new investors (rare, favorable to founders). Post-round top-up: pool sized after round based on need (favorable, requires negotiation). Split: half pre-money, half post-money (compromise; increasingly common in 2025-2026).

Frequently asked questions

How much does the pre-money option pool cost founders?

On a $10M pre-money round with a 15% pool created pre-money, founders bear ~1.5% additional dilution vs. a post-money structure. Over multiple rounds, this compounds to 5-8% total additional dilution.

What if we don't grant all the pool?

Unused pool doesn't disappear — it either dilutes into the next round's top-up (reducing top-up need) or, rarely, is retired back to founders. Efficient use benefits founders.

Should we grant options or RSUs?

Options at seed through Series C (early exercise for tax benefits). RSUs typically appear at late-stage/pre-IPO when 409A valuations make options prohibitively expensive to exercise.
