ESOP pool sizing: how big, and who really pays for the dilution?
Two questions decide what an ESOP pool really costs you: how big it is, and when it is created. Size it to your actual hiring plan, not a round number. And know that a pool created pre-money comes out of the founders' share, while a pool created post-money is shared with the new investor. That timing point, the “option pool shuffle”, can move real ownership by several percent, and it is negotiable.
The short answer
An ESOP pool is the block of equity reserved for employee options. Investors want it large enough to hire the next team; founders want it no larger than needed, because every unallocated share still dilutes them. The two decisions:
- Size: map the senior hires for the next 12 to 18 months and the equity each expects, then set the pool to that, not to a habit like “10%”.
- Timing: decide, and negotiate, whether the pool is created pre-money or post-money.
Pre-money vs post-money pool, side by side
| Dimension | Pool created pre-money | Pool created post-money |
|---|---|---|
| Who bears the dilution | Existing shareholders, mostly the founders | Shared with the incoming investor |
| Effect on valuation | Lowers the effective pre-money below the headline | Headline and effective valuation stay closer |
| Who usually prefers it | Investors | Founders |
| What to watch | A large pool quietly discounts your valuation | Investors may resist; it is a negotiation |
Rough pool sizes by stage
| Stage | Common pool range | Why |
|---|---|---|
| Pre-seed / seed | Often around 10% | Room for the first senior hires and early team |
| Series A | Frequently topped up toward 10 to 15% | Refresh for the next layer of leadership |
| Series B and beyond | Topped up to the hiring plan | Sized to specific roles, not a percentage habit |
These are indicative ranges, not a rule. The right number is whatever your named hiring plan needs. Norms shift by market and investor, so treat percentages as a starting point, not a target.
Size it to the plan, not the percentage
The cleanest way to size a pool is bottom-up: list the senior roles you will hire before the next round, attach an equity band to each, add a buffer, and total it. That number, expressed as a percentage of the fully diluted cap table, is your pool. A pool set this way is defensible in a negotiation, because it maps to real hires, rather than a round figure an investor can push around.
The shuffle, and why timing is money
When an investor asks for a pool to be created pre-money, the new option shares are carved out of the pre-money valuation, so the dilution falls on the existing shareholders, which is mostly the founders. The headline valuation looks unchanged, but your effective valuation is lower. Creating the pool post-money spreads that dilution. Neither is wrong, but the difference is real ownership, so it belongs in the term-sheet conversation, not the fine print.
ESOPs across borders
If your structure spans India and the US, the pool question gets a second layer: which entity grants the options, how they are taxed for the employee, and how a later flip treats the existing grants. An LLP cannot run a normal option pool at all, which is one more reason the vehicle you choose matters; see Pvt Ltd vs LLP vs C-corp. Design the pool with the structure in view, not after.
What we check on the cap table
- Hiring plan: the named roles and equity bands the pool is meant to cover.
- Timing: whether the pool is pre-money or post-money, and what that does to founder ownership.
- Grant entity and tax: which company grants, and how options are taxed for employees.
- Later rounds: how the pool refreshes, and how a flip carries existing grants.
Frequently asked questions
How big should an ESOP pool be?
Size the pool to your actual hiring plan for the next twelve to eighteen months, not to a round number. Early-stage pools are commonly around ten percent of the cap table, but the right figure depends on how many senior hires you need and what equity each will expect. Ranges vary widely, so map the hires first.
What is the option pool shuffle?
It is the practice of creating or topping up the ESOP pool pre-money, before an investment closes. Because the new shares come out of the pre-money valuation, existing shareholders, usually the founders, bear the dilution rather than the incoming investor. It lowers the effective pre-money valuation below the headline number.
Does the ESOP pool dilute founders or investors?
It depends on when the pool is created. A pool created pre-money dilutes the existing shareholders, which is mostly the founders. A pool created or counted post-money is shared more evenly with the new investor. This single timing point can move real ownership by several percent, so it is worth negotiating.
Should the ESOP pool be created before or after the round?
Investors usually prefer it created pre-money, so founders absorb the dilution; founders prefer it post-money, so it is shared. There is no universally correct answer, but you should know which one is on the table, size the pool to a real hiring plan, and negotiate the timing deliberately rather than accepting the default.
Can you increase the ESOP pool later?
Yes. Pools are commonly topped up at each round as the team grows, and a later increase can be negotiated like any other term. The trade-off is that every top-up dilutes the cap table again, so it is better to size each pool to a real plan than to over-provision early or scramble to refresh mid-hire.
