Vesting Schedules: The Complete Guide for Founders and Employees

What is Vesting?

Vesting is the process by which you earn ownership of equity over time. You're granted shares or options upfront, but you don't actually OWN them until they vest. Leave before they vest, and you forfeit unvested equity.

Vesting exists to align long-term commitment with ownership. It protects companies from co-founders who leave after 3 months, employees who quit after getting their grant, and consultants who don't deliver.

Standard vesting: 4 years with a 1-year cliff. This is so common it's essentially market standard for employees and founders.

The Standard 4-Year Vest

Structure:

• Total duration: 4 years (48 months)
• Cliff: 1 year (12 months)
• Monthly vesting: After cliff, 1/48th vests monthly

Example: You get 48,000 options on January 1.

• Month 1-11: 0 vested
• Month 12: 12,000 vest (25%)
• Month 13: 13,000 total (12,000 + 1,000)
• Month 24: 24,000 total (50%)
• Month 48: All 48,000 vested

If you leave in Month 11, you get nothing. If you leave in Month 13, you keep 13,000 vested options but forfeit 35,000 unvested.

The Cliff Explained

The cliff is a minimum commitment period before ANY equity vests. It's all-or-nothing: stay until the cliff and 25% vests at once. Leave 1 day before and you get zero.

Purpose: Protects companies from short-term hires. If an employee doesn't work out in the first year, they leave with nothing. No messy cap table clutter from 100 people who each own 0.01%.

Standard cliff length: 1 year for employees and founders, 3-6 months for advisors/consultants.

Some companies eliminate the cliff for senior executives (SVP+ level) as a recruiting incentive. "No cliff, start vesting monthly from day one." This is rare but not unheard of.

Founder Vesting: The Most Important Cap Table Decision

Should founders vest? Absolutely. Always. No exceptions.

The horror story: Two co-founders start a company 50/50 with no vesting. One quits after 6 months to "pursue other opportunities." The remaining founder builds the company for 5 years. The departed founder still owns 50% despite contributing 6 months of work.

Standard founder vesting terms:

• 4-year vest (sometimes 3-year for very experienced founders)
• 1-year cliff (or no cliff if founders already worked together 12+ months)
• Credit for prior work: If you've been working on the company for 6 months, negotiate for 6-12 months of immediate vesting

Investors will require founder vesting in your first priced round. Do it yourself from day one to avoid retroactive vesting (which has tax complications).

Acceleration Clauses

Acceleration provisions cause unvested equity to vest immediately upon certain trigger events. Two types: single-trigger and double-trigger.

Single-Trigger Acceleration

All unvested equity vests upon a single event (usually acquisition). Example: You have 2 years remaining to vest. Company gets acquired. All your unvested equity vests immediately.

Investors hate single-trigger acceleration (except for founders/executives) because it creates perverse incentives. Employees with 3.5 years vested want the acquisition to happen NOW so they get the final 0.5 years accelerated. Employees with 0.5 years vested want to delay until they have more vested.

Double-Trigger Acceleration

Requires TWO events: (1) acquisition AND (2) termination without cause within 12-18 months post-acquisition. This is the market standard compromise.

Example: Company acquired. You stay on. Your role is eliminated 6 months later. Double-trigger fires: all unvested equity vests.

Why acquirers like this: They're acquiring you for your team. Double-trigger ensures employees stay through the transition instead of getting their equity and quitting immediately.

Vesting for Different Roles

Founders: 4-year vest, 0-1 year cliff, double-trigger acceleration

Executives (C-level): 4-year vest, 1-year cliff, double-trigger acceleration, sometimes signing bonus with partial immediate vesting

Employees: 4-year vest, 1-year cliff, no acceleration (or double-trigger for senior roles)

Advisors: 2-year vest, quarterly or monthly vesting, 3-6 month cliff

Board members: Often grant annual or quarterly, no traditional vesting (they vest immediately or on fixed schedule)

Refresh Grants and Retention

An employee joins, gets 40,000 options vesting over 4 years. After 2 years, they're 50% vested with 2 years remaining. To retain them, you grant a "refresh" of another 40,000 options with a new 4-year schedule.

Now they have:

• Original grant: 20,000 vested, 20,000 unvested over next 2 years
• Refresh grant: 0 vested, 40,000 unvested over next 4 years

Total: 60,000 options, 20,000 vested, 40,000 unvested, vesting schedule extends to Year 6.

This is common for high performers. It ensures they always have 2-3 years of vesting ahead, creating continuous retention incentive.

Common Vesting Mistakes

Mistake #1: No Founder Vesting

Co-founder quits early, keeps full equity. Company dies or surviving founder gets massively diluted trying to buy them out.

Mistake #2: Immediate Vesting for Advisors

You grant 0.5% to an advisor with immediate vesting. They give you 2 hours of advice and disappear. You just gave away 0.5% for nothing.

Mistake #3: Single-Trigger Acceleration for Everyone

Company gets acquired. Everyone's equity vests, everyone quits. Acquirer gets an empty shell. Deal falls apart or gets repriced.

Mistake #4: Not Tracking Vesting Start Dates

Employee joins May 1 but option grant is dated June 15 (when board approved). Vesting starts June 15, not May 1. Employee is upset—they "lose" 1.5 months of vesting.

Solution: Backdate vesting start date to hire date (legal and common) or grant immediately upon hire.

Negotiating Vesting as an Employee

What you can negotiate:

• Accelerated vesting credit: "I've been consulting for 6 months. Can I get 6 months of immediate vesting?"
• Shortened cliff: "Can we do 6 months instead of 12?" (Rare but possible for senior roles)
• Acceleration: "Can I get double-trigger acceleration?" (For C-level, usually yes. For IC, usually no.)
• Extended exercise window: "Can I get 5-year post-termination exercise instead of 90 days?"

What you cannot negotiate:

• No vesting at all (instant ownership)
• Shorter than 4-year total duration (maybe 3 years for very senior roles, but rare)
• Single-trigger acceleration (investors will block this)

Conclusion

Vesting is the mechanism that ensures equity tracks commitment. The standard 4-year vest with 1-year cliff exists for good reason: it balances risk between company and employee.

For founders: Implement vesting from day one, even if you trust your co-founders completely. For employees: Understand your vesting schedule, track your vest dates, and negotiate acceleration if you're senior enough. For everyone: Remember that unvested equity is a promise, not ownership. Plan accordingly.
