At Stripe, RSUs are subject to a 4-year vesting schedule: 25% vests in each year (6.25% every 3 months). Alternatively, Stripe also has the following 1-year vesting schedule: 100% vests at the end of each year (cliff).

An RSU refresh is available for employees after 9 months in the company. Alternatively, Stripe has now begun issuing single year vesting schedules.
