Vesting Schedules Explained: How to Protect Your Cap Table

Vesting is the mechanism that ensures equity is earned over time, not given all at once. Without vesting, a co-founder who leaves after three months keeps the same ownership as one who stays for five years. Investors will not fund a company without vesting in place. This guide explains how vesting works for both founders and employees, the different schedule types, acceleration triggers, and how to track it all on your cap table.

Why vesting exists

Vesting solves the "free rider" problem. If you give someone 25% of the company on day one with no strings attached, they can walk away immediately and keep that ownership forever. Vesting creates a time-based (or milestone-based) release schedule: equity is "earned" gradually, and unvested equity is forfeited upon departure.

This protects three groups:

• Remaining founders: if a co-founder leaves early, their unvested shares return to the company, preventing "dead equity" on the cap table.
• Investors: they want to know that the team is incentivized to stay and build value over the long term.
• Future employees: returned unvested shares can be recycled into the option pool for new hires.

The standard vesting schedule: 4 years with a 1-year cliff

Alternative vesting structures

Founder vesting: special considerations

Founder vesting is different from employee vesting in several ways:

• Reverse vesting: founders typically receive all their shares at incorporation but subject to a "reverse vesting" arrangement. If the founder leaves before fully vested, the company has the right to repurchase unvested shares at the original price (often nominal).
• Credit for time served: if co-founders have been working on the company for a year before setting up vesting, they should get credit for that time. A common approach is to start the vesting clock on the date the company was founded, not the date the vesting agreement is signed.
• Investor-imposed vesting: investors will almost always require founders to be on a vesting schedule as a condition of investment. If you set up vesting before fundraising, you have more control over the terms.
• No cliff for founders (sometimes): some founders negotiate away the cliff since they have already demonstrated commitment by founding the company. This is reasonable if the company is more than a year old.

Acceleration clauses

Acceleration allows unvested equity to vest early, usually triggered by specific events:

• Single-trigger acceleration: all (or some) unvested equity vests immediately upon a change of control (acquisition, merger). This benefits the individual but can make acquisitions more expensive and is investor-unfriendly.
• Double-trigger acceleration: unvested equity vests only if the individual is terminated (or constructively dismissed) within a defined period (usually 12 months) after a change of control. This protects both the individual and the acquirer. More common and generally preferred.
• Partial acceleration: a compromise where a portion (e.g., 50%) of unvested equity accelerates on a trigger event, with the rest continuing on the original schedule.

Tracking vesting on your cap table

For each equity holder subject to vesting, your cap table should track:

• Total grant size (shares or options)
• Vesting start date
• Cliff date
• Monthly/quarterly vesting amount
• Shares vested to date
• Shares unvested (remaining)
• Shares exercised (for options)
• Current status (active, terminated, fully vested)

How eSignHub simplifies vesting management

eSignHub's cap table automatically tracks vesting for every shareholder and option holder. Set the vesting schedule once, and the system calculates vested vs unvested equity in real time. When someone leaves, update their status and the unvested shares automatically return to the pool. No spreadsheet formulas, no manual date calculations, no errors.
