What Is Cliff?

Key definition

A cliff is the initial waiting period in a vesting schedule during which no shares or options vest, after which a significant portion vests at once if the individual is still with the company. It is most commonly used in founder and employee equity arrangements to ensure that ownership is earned over time, not granted immediately.

In startup compensation, the cliff is a structural safeguard. It prevents someone from joining briefly, receiving equity, and leaving with a permanent stake before contributing meaningful value.

Cliff meaning

The cliff’s meaning in equity arrangements centres on commitment and protection. A common cliff definition is a one-year cliff within a four-year vesting schedule, where nothing vests until the first anniversary of the start date. At that point, a defined percentage, often 25%, vests immediately.

If the individual leaves before the cliff ends, they typically receive no vested equity at all.

In practice, the cliff stands for safeguarding the company from awarding ownership to short-term contributors while rewarding those who remain and help build long-term value.

How a cliff works in a typical vesting schedule

The most common structure looks like this:

  • Total vesting period: 4 years
  • Cliff: 12 months
  • Vesting after cliff: 25% vests at the 1-year mark
  • Remaining 75%: vests monthly or quarterly over the following 3 years

Example:

An employee is granted 40,000 options under a four-year schedule with a one-year cliff.

  • Months 0–11: 0 options vested
  • Month 12: 10,000 options vest (25%)
  • Months 13–48: Remaining 30,000 vest gradually

If the employee leaves at month 10, they walk away with nothing.
If they leave at month 18, they keep only the portion that has vested.

Why do companies use a cliff

Protecting the cap table

Equity is scarce and valuable. A cliff ensures that ownership remains aligned with sustained contribution, not short-term participation.

Reducing “dead equity”

If someone departs very early without a cliff in place, they may retain equity despite minimal contribution. That can complicate future fundraising and distort incentives.

Signalling long-term commitment

Investors expect structured vesting, particularly for founders. A cliff demonstrates that equity is tied to continued involvement and performance.

Cliff is the founder of the arrangements

Cliffs are not only for employees. Founder vesting schedules often include cliffs as well, particularly in venture-backed companies.

Even if founders incorporated the company together, investors frequently require founder shares to be subject to vesting with a cliff. This reduces the risk that a departing founder retains a large ownership stake without ongoing involvement.

Cliff vs vesting: what’s the difference?

  • Vesting is the broader process of earning equity over time.
  • Cliff is the initial “all-or-nothing” period before any vesting occurs.

The cliff does not replace vesting; it delays the first vesting event to ensure meaningful commitment.

Practical considerations

When designing a cliff, founders should consider:

  • Industry norms (one year is common but not mandatory)
  • Role seniority and recruitment competitiveness
  • Interaction with good leaver/bad leaver clauses
  • Alignment with fundraising expectations

Cliffs are most effective when they are transparent, clearly documented in option plans or shareholders’ agreements, and consistently applied across the team.

Ultimately, the cliff is about fairness: it rewards sustained contribution and protects the long-term health of the company’s ownership structure.
