# What Is Employee Option Pool?

> An employee option pool is shares reserved in the cap table for future equity grants to employees, advisors, and executives—typically created or expanded at funding rounds.

**Employee option pool** is the reserved portion of a startup's cap table dedicated to equity compensation for team members—not yet allocated to individuals, but authorized for future grants.

## How it works

Before a Series A, a company might have 15% of fully diluted shares in the pool. As employees join, the board grants options from the pool per the [equity incentive plan](/glossary/equity-incentive-plan). Unallocated pool remains available; allocated but unvested options count against the pool until exercised or cancelled.

Investors frequently negotiate **pool top-ups** at financing: e.g., increase pool from 10% to 15% pre-money, which dilutes existing shareholders before new money enters. Founders feel this as "option pool shuffle"—dilution for hiring budget baked into pre-money valuation.

409A valuations (U.S.) set strike prices for new grants. Refresh grants and promotions draw from remaining pool; exhausted pools require board and often investor approval to expand.

## Why it matters

- **Founders:** Right-size the pool for 18–24 months of hiring plan. Too small means mid-round renegotiation; too large dilutes you upfront.
- **Investors:** Pool is part of ownership math in term sheets. Lead investors want enough unallocated equity to attract talent post-close.
- **Employees:** Offer letters reference option count and ownership percentage—verify pool has room and understand dilution from future rounds.

## Common mistake

Assuming the pool dilutes only employees. Pool expansion dilutes **founders and common** proportionally unless deal structure says otherwise—often it is pre-money dilution hitting founders hardest.

## FAQ

### What is Employee Option Pool in simple terms?

A block of company shares set aside to hire and retain people through stock options or RSUs—usually 10–20% of fully diluted cap table at seed/Series A, varies by stage.

### Why does Employee Option Pool matter?

Pool size affects founder dilution. Investors often ask for pool expansion before their investment so their ownership is not immediately diluted by future hires.
