Cliff Vesting

A vesting structure where no equity is earned until a specific date — after which a lump sum vests at once.

Cliff vesting is a component of an equity grant where the employee receives no vested shares until they reach a defined milestone — typically 12 months of employment — after which a large block vests at once. This is the 'cliff.' After the cliff, vesting typically continues on a monthly or quarterly schedule for the remaining grant period. A standard four-year grant with a one-year cliff means 25% vests at month 12, then 1/48th of the total vests each month for the following 36 months.

The one-year cliff is the most common structure in startup equity grants. It serves as a retention mechanism: employees who leave before 12 months receive nothing. It also protects the company from issuing equity to employees who turn out to be a bad fit before the relationship has been properly evaluated. Cliffs are typically non-negotiable at most companies, but their framing — and what you negotiate around them — matters considerably.

From a negotiation standpoint, the cliff creates a specific problem when you're leaving unvested equity at a current employer. If you're six months from vesting $100,000 in equity and the new role has a 12-month cliff, you're facing an 18-month window where you hold nothing at either company. This is the right context in which to negotiate a signing bonus or accelerated vesting — not to ask the company to eliminate its cliff, but to bridge the specific economic gap the transition creates. Frame it as a real number: 'I'm leaving $95,000 in unvested equity — can we discuss how to make the transition work?'

The cliff creates a well-documented perverse incentive: employees who are mildly dissatisfied near the 12-month mark often stay through the cliff date rather than leave at the right time, then depart shortly after vesting. Companies are aware of this dynamic and many will move quickly to offer a raise or equity refresh to retain employees they want to keep after the cliff. If you're in that position and genuinely undecided, the month approaching the cliff is a legitimate time to have a career conversation with your manager — not as a threat, but as an honest check-in.

Why Companies Use Cliffs

  • Retention — employees have a strong financial incentive to stay through at least the cliff date.
  • Quality filter — it gives employers time to evaluate fit before significant equity transfers.
  • Market norm — one-year cliffs are so standard in startup equity that deviating requires explanation.
  • Simplicity — a cliff plus monthly vesting is easy to communicate and model for both parties.
  • Mutual alignment — the cliff period establishes whether both parties want to continue before a significant equity transfer occurs.

What Happens If You Leave Before the Cliff

  • Voluntary resignation before the cliff: you forfeit all unvested equity with no exceptions in most plans.
  • Involuntary termination (layoff) before the cliff: same result at most companies — all unvested equity is forfeited unless there's an acceleration provision.
  • Some companies include single-trigger or double-trigger acceleration that vests equity in a layoff — this is worth asking about before accepting an offer.
  • Negotiating a shorter cliff is possible if you're leaving unvested equity elsewhere and framing it as a bridge.
  • If your cliff date is approaching and you're laid off: ask specifically about any cliff-date acceleration in your equity plan document.

Negotiating Around the Cliff

  • Quantify what you're leaving: get the exact value of unvested equity at your current employer and use it as a specific negotiation anchor.
  • Request a signing bonus sized to bridge the cliff gap — especially if you're within 6 months of a large vest.
  • Ask about single-trigger acceleration in an acquisition — if the company is acquired before you hit the cliff, this ensures you don't lose your grant.
  • Understand your post-termination exercise window for options: some plans give only 90 days to exercise after leaving, which can force tax decisions under pressure.

Example

An engineer receives 48,000 RSUs vesting over 4 years with a 1-year cliff. At month 12, 12,000 RSUs vest (25%). After that, 1,000 RSUs vest monthly for the remaining 36 months. She's also leaving 20,000 unvested options at her previous employer worth approximately $60,000 — which she negotiates as a $60,000 signing bonus from her new employer.
