Full Definition
A vesting schedule is the timeline and conditions under which equity compensation grants become fully owned by the employee. Until equity vests, the employee holds a conditional interest—if they leave the company before vesting, unvested awards are typically forfeited. The standard vesting schedule in venture-backed startup employment is 4 years with a 1-year cliff: no equity vests during the first year of service, 25% vests at the one-year anniversary (the "cliff"), and the remaining 75% vests in equal monthly or quarterly increments over the following 3 years. This structure ensures that equity is only delivered to employees who provide a minimum of one year of service, while rewarding long-tenured employees with progressively larger ownership stakes. Vesting schedule design sends important cultural signals about the company's employee commitment philosophy. Four-year schedules with back-loaded vesting (less in early years, more in later years) create stronger retention incentives than front-loaded schedules but can feel punitive to employees who leave after 2-3 years having built significant value. Accelerated vesting provisions—allowing faster or immediate vesting under specific conditions—reflect the company's willingness to share value when employees contribute to value-creating outcomes regardless of tenure. The vesting schedule interacts importantly with the hiring market: companies offering more favorable vesting terms (shorter schedules, more acceleration provisions) have an advantage recruiting employees who are weighing competing offers. When a company recruits an employee who is leaving unvested equity at their current employer, offering additional equity to compensate for the forfeited value (a "buyout grant") is common practice—but the replacement grant typically starts its own vesting schedule from the new employment date, not the original grant date. Understanding the fully-diluted cost of vesting schedules across the entire employee population is important for cap table management and dilution modeling.
FAQs
Can vesting schedules differ by employee level or hire date?
Yes—vesting schedules can and often do differ by level, hire date, and grant purpose. Early startup employees may receive 4-year vesting; later hires after product-market fit may receive 4-year schedules with different cliff provisions. Executive hires often negotiate modified vesting terms—shorter vesting periods, enhanced acceleration, or performance-based vesting that differs from standard employee grants. However, too much variation creates perceived inequity and administrative complexity; most companies standardize on a small number of vesting schedule templates rather than fully individualized terms.
What happens to vesting when a company is acquired?
Acquisition treatment of unvested equity is defined in the merger agreement and the equity plan documents. Most acquisition agreements offer employees one of three outcomes: assumption (the acquirer assumes unvested grants, converting them to acquirer equity with the same vesting schedule), acceleration (unvested grants accelerate and become fully vested at close), or cash-out (unvested grants are paid out in cash and cancelled). Double-trigger acceleration (requiring both change of control and involuntary termination) is the most common executive provision, balancing the acquirer's interest in retaining management with management's interest in not losing equity value if they are terminated post-acquisition.
