Option Pool

Pre-Money vs Post-Money Option Pool

A pre-money option pool is created before the investor's shares are issued, so founders absorb its dilution. A post-money pool is created after, so the investor shares the cost.

Valuation timing for option pool top-ups

Pre-money valuation is the value agreed for the company before new investment is added, and post-money valuation is pre-money plus the new money invested. Both are explained in more detail at pre-money valuation and post-money valuation. Whether the option pool top-up is counted as part of the pre-money share count or added afterward changes who pays for it, even though the headline pre-money valuation figure can look the same in both cases.

Founder ownership under different pool timings

A company agrees a 10,000,000 pre-money valuation and raises 2,500,000, giving a 12,500,000 post-money valuation and a 20% investor stake. The investor also asks for a 10% fully diluted pool. If the pool is created pre-money, its cost is added to the pre-money share count, so founders' fully diluted percentage falls further than the headline pre-money valuation implies. If the pool is created post-money, the investor's 20% and the pool's 10% both come out of the combined post-money share count, and founders retain more, a distinction that matters most when read alongside pool dilution mechanics.

Numbers are illustrative to show the mechanic. Exact percentages depend on the specific share counts and round terms negotiated.

Term sheet discussions on pool reservation timing

  • Ask explicitly whether the quoted pre-money valuation already includes the pool top-up.
  • Model both pre-money and post-money pool scenarios before agreeing to a term sheet.
  • Treat the effective pre-money valuation, after accounting for the pool, as the real number to compare across offers.
  • Remember that a higher headline valuation with a large pre-money pool can be worth less to founders than a lower valuation with a smaller pool.

Clearing up pre-money and post-money pools

Why do investors prefer pre-money pools?
It protects their ownership percentage from dilution caused by future hiring, since the pool cost falls on existing shareholders instead.
Is the option pool shuffle common in Europe?
Yes, it is standard practice in many European term sheets, though the exact pool size and timing are negotiable.
How do I compare two term sheets with different pool assumptions?
Convert both to the same basis, usually the founders' resulting fully diluted percentage, rather than comparing headline pre-money valuations directly.
