Cliff Vesting

A vesting provision where no equity vests until a minimum service period (the cliff) is completed, protecting against early departures.

FAQs

What happens if an employee is terminated just before their cliff?

If terminated before the cliff with no acceleration provisions, the employee receives zero equity — all unvested shares are forfeited. This is why cliff timing is a significant factor in termination decisions. Some companies may provide severance that includes accelerating past the cliff as part of separation agreements, but this is negotiated individually.

Does the cliff apply to performance-based vesting too?

Performance-based vesting can also include a cliff structure, where a minimum performance threshold must be achieved before any vesting occurs. For example, options may not vest until the company achieves $5M ARR, then vest monthly thereafter. The cliff concept applies to any vesting mechanism, not just time-based schedules.

Is a 1-year cliff standard across all types of companies?

In US technology startups, yes — the 1-year cliff with 4-year total vest is essentially universal. In corporate environments and larger companies, different vesting designs are common, including 3-year cliff vesting for 401k matching, immediate vesting for RSU grants, or performance-based vesting without any time cliff.

Cliff vesting is a vesting structure in which no portion of an equity grant becomes vested until the employee has completed a minimum defined period of service — the 'cliff' — after which a specified percentage vests immediately. The most common application in startup equity compensation is a 1-year cliff, after which 25% of the grant vests in a lump sum.

The cliff serves a protective function for the company: it ensures that employees who leave in the first year — whether voluntarily or through termination — receive no equity benefit, protecting existing shareholders from dilution by short-tenure employees. Without a cliff, a continuous monthly vesting schedule would grant even a 1-month employee a small equity stake.

For employees, the cliff creates a critical decision point: leaving just before the cliff forfeits significant value, while crossing the cliff triggers immediate vesting of a meaningful award. This creates strong retention pull around the 1-year mark and is intentional by design.

In 401(k) retirement plans, cliff vesting works similarly but with different timeframes. ERISA requires that employer contributions vest either on a cliff schedule (100% vesting after no more than 3 years of service) or a graded schedule (at least 20% per year from year 2 through year 6). Plans can have shorter vesting periods but not longer.

Combined vesting schedules — such as a 1-year cliff followed by monthly vesting — are the norm in startup equity, providing initial protection (the cliff) followed by smooth ongoing incentives. For executive grants, 2-year or 3-year cliffs are sometimes used to emphasize long-term retention.
