ESOP

Also called: Employee Stock Option Plan, Employee Stock Ownership Plan

TL;DR

Employee Stock Option Plan, the legal structure that lets a company grant options to employees at a defined strike price, governed by board approval and 409A.

An ESOP is the legal framework for issuing options to employees. The board adopts an option plan that defines pool size, eligibility, vesting defaults, and other administrative rules. Individual grants are then approved by the board within the plan's terms.

In US practice, 'ESOP' is commonly used interchangeably with 'option pool', though strictly an ESOP can also refer to a different (defined-benefit) employee ownership structure. In international SaaS contexts, the acronym usually means the option plan.

Worked example

A pre-Series-A SaaS reserves a 12% post-close ESOP. By Series B (24 months later), 7% has been granted to 28 employees, 1% has been forfeited (returned to pool), and the lead asks for a top-up to 13% at close, diluting founders by an additional 1.4 percentage points.

Common pitfalls

•Granting options without board approval under the ESOP.
•Using outdated 409A valuations to set strike prices.
•Failing to refresh the ESOP pool size before it runs out.
