Vesting (and the cliff)
Also known as: vesting cliff · vesting schedule
Vesting is the schedule on which an employee earns their granted shares — most commonly 4 years with a 1-year cliff, meaning no shares vest until 12 months in, then monthly thereafter.
How it works
Standard 4/1 vesting: 0% vests until the 1-year anniversary (the 'cliff'), then 25% vests at once and 1/48th of the grant each month for the remaining 36 months. Founders typically also vest on the same schedule — investors require this to lock founders in. Some startups offer 6-year vesting (Stripe famously does this), and acceleration provisions speed up vesting on a change of control.
