Reverse Vesting

Reverse vesting is the mechanism where founder stock already issued at company formation becomes subject to a vesting schedule. Unvested shares are subject to company repurchase at original purchase price if the founder departs early, making the structure "reverse" because shares are owned upfront but earned over time through continued service, with 4-year vesting and a 1-year cliff being standard for founder shares in venture-backed startups. It's the structure that protects co-founders and investors from a founder taking equity and leaving.

The mechanics:

Initial issuance: founder receives shares at formation (typically restricted stock, not options).

Vesting schedule applied: 4-year monthly vesting with 1-year cliff is standard.

Repurchase right: company has right (not obligation) to repurchase unvested shares at original price if founder departs.

Vested vs. unvested: vested shares are founder's permanently; unvested subject to repurchase.

83(b) election: founders typically file 83(b) within 30 days of grant to pay taxes upfront at low value.

The standard schedule:

4-year vest with 1-year cliff:

• Year 0-1: 0% vested. If founder leaves, company repurchases all shares.
• Year 1: 25% vests at cliff. After cliff, monthly vesting begins.
• Year 1-4: 1/48th of total vests monthly.
• Year 4: 100% vested.

Sometimes longer:

• 5-year vest at some companies (especially later-stage).
• 1-year cliff still standard.

Why investors require reverse vesting:

Protects against founder departure: if founder leaves at year 1, company gets back 75% of their shares for redistribution.

Aligns long-term incentives: founder rewarded for staying and building.

Equity for replacement: unvested shares become available for hiring replacement.

Investor protection: ensures founders are committed long-term.

The acceleration provisions:

Single-trigger acceleration: vesting accelerates on change of control (acquisition). Typically 25-50% acceleration.

Double-trigger acceleration: vesting accelerates on change of control AND involuntary termination within specified period (typically 12 months). More common than single-trigger.

Founder negotiation: founders often negotiate for vesting credit for time pre-incorporation, single-trigger acceleration, or longer post-departure exercise periods.

What founders should know:

File 83(b) within 30 days: pay taxes on full value at grant (typically very low) rather than as shares vest (typically much higher).

Understand acceleration terms: single-trigger vs. double-trigger; what triggers count.

Cliff is firm: leaving before 1 year means losing all shares (unless company waives).

Repurchase price: typically original purchase price (often $0.001 per share for founders).

What founders get wrong: Skipping reverse vesting at formation thinking it's only for employees, then facing investor pressure to add it later. Or missing the 83(b) deadline and paying ordinary income tax on vesting. The right discipline: reverse vesting from day one; 83(b) within 30 days; clear acceleration terms.
