Figuring out how much equity to reserve for early employees is a high-stakes guessing game. In the early days, guessing wrong means either running out of shares for top talent or severely diluting your own stake before finding product-market fit. Here is a simple framework to lock in your numbers before you talk to investors.

A reliable option pool model helps you reserve just enough equity to hire your next milestone team without unnecessarily diluting founders.

• Benchmark: Reserve 10-15% of total shares for your pre-seed equity pool.
• Rule: Only size the pool for the exact hires you need over the next 18 to 24 months.
• Warning: Do not create a massive 20-25% pool just because investors ask for it — this dilutes you immediately.

Use this checklist of variables to build your hiring plan and option pool calculator for startups model.

1. Hiring timeline. Map exactly who you need to hire between now and your next funding round — typically a 15 to 24 month window.
2. Role categories. Group future hires by impact level, like founding engineer vs junior marketer.
3. Equity ranges. Assign an equity bracket to each role.
4. Refreshers. Buffer your estimate for refresh grants to keep high performers incentivized after their initial cliff.
5. Advisor shares. Allocate a small sliver for critical early advisors. Looking at cap table 2025 examples can help you visualize how this fits into the broader ownership structure.

Always base your pool size on hard data. You can check reputable external sources like Index Ventures' equity benchmarking data to see standard market brackets. Early engineering talent usually falls in the 0.5-1.5% range.

Sample math: If you need 3 engineers at 0.5-1.0% each, 1 head of growth at 1.0-2.0%, and 2 advisors at 0.1-0.2% each, your total required pool for this phase is roughly 2.7-5.4%. You would set up a pool closer to 10-15% to have a safe buffer for unexpected hires.
