How to Negotiate Option Pool Size

Investors often request a 15-20% option pool as a standard term. But the right pool size depends on your actual hiring plan for the next 18-24 months. Here is how to push back with data:

  1. Map out every hire you plan to make before the next round
  2. Assign equity grant ranges for each role (see table below)
  3. Total the grants and add a 10-20% buffer for opportunistic hires
  4. Present this bottoms-up number instead of accepting a top-down percentage

Vesting Schedules

Standard 4-Year Vest, 1-Year Cliff

The industry standard in the US and UK. Nothing vests during the first year (the cliff). After the cliff, 25% vests immediately. The remaining 75% vests monthly or quarterly over the next 36 months. If someone leaves before the cliff, they get nothing.

Fully Diluted vs Basic Share Count

The basic share count only includes shares that have been issued. The fully diluted share count includes everything: issued shares, all outstanding options (vested and unvested), convertible notes, SAFEs, and any reserved pool shares. Investors always use the fully diluted count when calculating ownership percentages. A founder might own 60% on a basic basis but only 42% on a fully diluted basis once the option pool, convertible notes, and reserved shares are included.
