Is My New Executive’s Equity Single Trigger or Double Trigger, and Why Does It Matter? 

Did I just hand my new CFO a parachute I can’t afford, or a promise that protects no one? 

I raised my round, hired the VP of Sales or CFO I needed, and the offer letter mentioned “accelerated vesting on a change of control.” It sounded like a nice perk. I signed it and moved on. 

That sentence decides who gets paid, how much, and when, if my company gets acquired. I don’t want to learn what it says during a live deal, with a buyer’s lawyer reading it back to me. 

Plain-English Breakdown 

Acceleration language controls what happens to an executive’s unvested stock (shares not fully earned yet) when the company sells. Two versions exist, and they aren’t interchangeable. 

Single Trigger: One Event, Full Payout 

Single trigger means one event, the sale itself, vests all remaining stock immediately. 

• The deal closes and equity fully vests, whether the executive stays or leaves. 

• Acquirers dislike this. It pays out key people before the buyer has any leverage to keep them. 

• Buyers often demand a price reduction to offset the cost, which comes out of my proceeds. 

Double Trigger: Two Events, Conditional Payout 

Double trigger requires two things: the change of control, and a qualifying termination (fired without cause, or resignation for “good reason”) within a set window, usually 12 months. 

• If the buyer keeps the executive on, the stock keeps vesting normally. 

• If the buyer fires them or guts their role, the remaining equity vests immediately. 

• This is what institutional buyers expect. It protects against a post-close purge, without a payday for simply staying employed. 

Why the Difference Changes My Deal, Not Just Their Payout 

In an acquisition, the buyer’s counsel reviews every executive’s equity terms. Single trigger grants get flagged, priced into the offer, or made a closing condition. A funded company preparing for a sale can’t afford this surprise in the data room. Take an executive whose single trigger grant accelerated in full the moment a deal closed. The buyer treated that windfall as a cost of the transaction and priced it directly into a lower offer for the company, so every other shareholder absorbed part of that one grant. 

Double trigger only works if “good reason” is defined: pay cut, demotion, relocation, or material change in duties. Vague language like “substantially diminished role” invites a fight over whether the trigger happened. Set a clear window, three to 12 months post-close, for the termination to count. 

Common Founder Mistakes 

• Assuming Any Acceleration Clause Is the Same. Founders see “acceleration on change of control” and assume it’s boilerplate. They never check whether it’s single or double trigger, or whether a qualifying termination is defined at all. The gap surfaces only when a buyer’s counsel starts pricing it into the deal. 

• Using Single Trigger to Sweeten the Offer. To win a competitive hire, founders sometimes offer single trigger as a differentiator. It feels generous and helps close the hire, until a buyer’s team asks why key people get paid regardless of whether they stay. What looked like a recruiting win becomes a liability at the exact moment a founder has the least leverage to fix it. 

• Leaving “Good Reason” Undefined. Founders copy a template clause without customizing “good reason.” Missing triggers turn every termination into a negotiation, not a formula. 

10-Minute Self-Check 

Before I hire or promote another executive with equity, I work through this: 

• Does the offer letter say “single trigger” or “double trigger” acceleration, in plain words? 

• If double trigger, is “good reason” defined with specific triggers, not vague language? 

• Is there a clear time window for the qualifying termination after a change of control? 

• Have I modeled what this clause costs if we get acquired next year? 

• Does every executive have consistent acceleration terms, not a patchwork of one-off deals? 

• Would a buyer’s counsel flag this clause as a closing condition? 

If I can’t answer these with confidence, my executive’s equity terms aren’t acquisition-ready yet. 

Bottom Line 

Acceleration language isn’t boilerplate. It decides who gets paid, how much, and when, on the day my company is sold. Getting it wrong costs money at the exact moment I have the least room to negotiate. That’s a decision worth getting right long before that day arrives.
