What the option pool shuffle is

The option pool shuffle happens when the company increases the option pool before the investment and counts the pool in the pre-money. Practically, this means existing shareholders fund the pool increase via dilution.

Why investors ask for it

  • They want enough equity reserved to hire after the round.
  • They want the pool increase to be reflected in the pre-money, not to dilute the new investors.

How to model it (simplified)

  • Start with current option pool % (fully diluted pre).
  • Choose a target option pool % post-money.
  • Solve for the additional pool needed, then compute the post-money split (existing vs investor vs pool).

Negotiation levers

  • Negotiate the target post-money pool size based on hiring plans.
  • Ask to split the pool increase between existing holders and new investors.
  • Use a cap table model to compare effective dilution across term sheets.

Modeling checklist

  • Include SAFE/note conversions in the pre-money fully diluted count.
  • Confirm whether the option pool is pre-money or post-money.
  • Check that all ownership percentages sum to 100% post-money.

Common mistakes

  • Using pool % defined on an inconsistent basis across versions of the cap table.
  • Forgetting other dilutive instruments (SAFEs/notes) when estimating founder dilution.
  • Chasing a headline valuation instead of negotiating the full dilution package.
