TL;DR

Accelerated vesting is a provision in an equity or compensation plan that causes unvested shares or units to vest earlier than the scheduled timeline, triggered by a specific event such as a company acquisition, change of control, or an employee's involuntary termination. For recruitment professionals, understanding accelerated vesting matters when placing candidates in roles where equity forms a significant part of the compensation package, particularly in technology, private equity-backed companies, and pre-IPO startups.

How Accelerated Vesting Works

Standard equity grants vest on a schedule, typically four years with a one-year cliff. Under a four-year vesting schedule, an employee earns 25% of their grant after 12 months, then the remaining 75% monthly or quarterly over the following 36 months. If they leave before vesting, unvested shares are forfeited. Accelerated vesting alters this schedule in specific circumstances.

The two main types are single-trigger and double-trigger acceleration. Single-trigger acceleration vests shares immediately upon one event, most commonly a change of control (acquisition, merger, or sale of the company). If an employee holds 400 unvested shares and the company is acquired, all 400 vest on the closing date. Single-trigger is more common in executive-level grants and is often negotiated individually.

Double-trigger acceleration requires two events to occur before vesting accelerates. The first trigger is typically a change of control. The second trigger is an adverse employment action within a defined period after the change of control, usually 12 to 24 months. Common second-trigger events include involuntary termination without cause, a significant reduction in responsibilities, or a required relocation. Double-trigger is more common for standard employee equity grants because it aligns incentives: employees who perform well after an acquisition retain their unvested equity on the normal schedule.

Why It Matters for Recruitment

Candidates evaluating offers at companies with equity components need to understand what happens to their unvested equity in acquisition scenarios. A candidate accepting a role at a Series C startup with 3,000 unvested options and no accelerated vesting clause may lose significant value if the company is acquired six months into their tenure and the acquirer eliminates their position. The same candidate with double-trigger acceleration retains their full unvested equity if they are terminated after the acquisition.

When placing candidates into roles with meaningful equity compensation, recruiters who understand accelerated vesting provisions can add real value in the placement conversation. Asking the client whether the role's equity grant includes single or double-trigger acceleration is a legitimate and useful qualification question. The answer affects how a candidate should evaluate the total compensation package.

This matters most in markets where equity is a significant portion of total comp. For a software engineer receiving a $150,000 base salary plus a $200,000 equity grant over four years, the vesting schedule and any acceleration provisions affect whether the effective annual compensation is $150,000 or $200,000 in an acquisition year. That difference is not a footnote; it is a $50,000 annual swing. Recruiters who can discuss this credibly differentiate themselves from those who treat equity as a line item.

Change of control provisions also affect how urgently a candidate at a target company might consider an external move. If a candidate has 18 months of unvested equity with no acceleration clause and credible acquisition rumors are circulating, they face a real financial calculation. A recruiter who understands this context can time a conversation appropriately and frame the opportunity correctly.

In Practice

A technology-focused executive search firm was placing a VP of Engineering at a Series B SaaS company. The base salary offer was $220,000 with a 40,000 share grant at $2.50 per share, valued at $100,000 over four years on a standard vesting schedule.

During due diligence, the recruiter asked the founder about the company's acquisition strategy. The founder disclosed that two strategic buyers had expressed interest at a potential valuation of $8 to $10 per share. The recruiter reviewed the offer letter with the candidate and confirmed it included a double-trigger acceleration clause covering 100% of unvested equity.

The candidate had been weighing a competing offer with a higher base ($240,000) but no equity. With the acceleration clause, the candidate modeled two scenarios: if the company was acquired at $8 per share within two years and they were terminated, their 40,000 shares would be worth $320,000 immediately. This analysis made the equity meaningful rather than speculative, and the candidate accepted the original offer.

The recruiter's ability to frame this conversation added direct value to the placement and positioned the firm as a specialist rather than a transactional recruiter. The candidate referred two colleagues to the firm in the following year.
