Founder Equity Agreement
What is a Founder Equity Agreement in Startups?
A Founder Equity Agreement is a legal document that outlines how ownership shares are divided among the founders of a startup. It specifies each founder's percentage of equity, their rights, responsibilities, and any conditions related to their ownership stake.

Why a Founder Equity Agreement Matters
A Founder Equity Agreement sets clear expectations about who owns what in the startup. This clarity helps prevent disputes later on, especially when the company grows or seeks investment. It also defines how equity might change if a founder leaves or if new founders join.
How a Founder Equity Agreement Works
The agreement details the percentage of shares each founder receives based on their contributions, such as time, money, or intellectual property. It often includes vesting schedules, which means founders earn their shares over time to encourage long-term commitment.
Examples of Founder Equity Agreement Terms
Common terms include the initial equity split, vesting period (often four years with a one-year cliff), buyback rights if a founder leaves, and decision-making powers tied to ownership. These terms protect both the founders and the startup's future.
