Latest / The Series A Show with Fexingo: Early-Stage Funding, Pitch Decks, and Startup Milestones / The Cliff Vesting Debate Every Founder Must Navigate
Transcript
- Lucas: You raise a Series A, you sign the deal, you celebrate — and then six months later one of your co-founders walks out the door with a quarter of the company's equity. That scenario is not hypothetical. Luna: And it happens more often than people think. I've seen it three times in my own network just in the past year. Lucas: Exactly. And the only thing standing between that outcome and a clean handoff is the vesting language in your term sheet. Specifically, how you handle the cliff. Luna: Before we get into the mechanics — if conversations like this are useful for what you're building or running, these episodes stay ad-free because of listener support. You can throw a few dollars at the tip jar at buy me a coffee dot com slash fexingo. Keeps the lights on, no pressure. Lucas: Yeah, it's a small way to keep this thing going. And now back to that cliff. So a standard four-year vesting with a one-year cliff means you get zero equity until month 12, then you get 25 percent vested — one year's worth — and the rest vests monthly. If you leave before month 12, you walk away with nothing. Luna: That's the baseline. But where it gets tricky is when the term sheet tacks on acceleration clauses. Single-trigger acceleration means if the company is acquired, all unvested equity vests immediately. Double-trigger means the equity vests only if you're acquired AND you're fired or you quit for good reason. Lucas: Right. And founders love single-trigger because it protects them in an exit. But VCs have been pushing back hard — especially in this market. Look at the public markets this week: Shopify down nearly 12 percent in five days, Palantir down over 15 percent, Coinbase down over 16 percent. That kind of volatility makes investors risk-averse, and they don't want to hand out acceleration that could dilute them in a down-round scenario. Luna: So what's the middle ground? I've seen some firms offer 'modified single-trigger' — acceleration only for a percentage of unvested shares, not all. Lucas: That's becoming common. The data from Q4 2025 shows that 68 percent of Series A term sheets now include some form of acceleration, but only 12 percent are pure single-trigger. The rest are double-trigger or modified. And the real negotiation isn't about whether acceleration exists — it's about the percentage and the triggers. Luna: Let's walk through a concrete example. Say a startup raises a $12 million Series A at a $60 million post-money. Four co-founders each have 20 percent fully diluted. Standard vesting. Then two of them leave before month 18. Lucas: If they leave at month 18, they've passed the one-year cliff. So they've vested 18 months worth — that's 37.5 percent of their 20 percent, or 7.5 percent of the company each. Combined, that's 15 percent of the cap table walking out the door. And the remaining founders and investors have to figure out how to reallocate or buy back that equity. Luna: And if those founders had single-trigger acceleration, and the company gets acquired at month 20 — they'd vest the full 20 percent each, even though they only worked 20 months. That's 40 percent of the company going to people who might not even be there post-close. Lucas: That's the nightmare scenario for VCs. And that's why they're pushing for double-trigger so hard. But there's a legitimate founder concern: if you're a key executive and the company gets acquired, the acquirer might replace you. Under double-trigger, you lose unvested equity unless you're fired. So founders argue they need single-trigger to align incentives. Luna: One solution I've seen work is 'double-trigger with a soft landing' — if the acquirer doesn't offer you a comparable role, that counts as good reason, so you still get acceleration. It's a hybrid. Lucas: That's smart. And it's becoming more standard. The key is to negotiate these terms before the term sheet, not after. If you wait until the lawyer sends the draft, you're reacting. Ideally, you have a conversation with the lead investor during the diligence phase: 'Here's our philosophy on retention. We want to make sure the team stays through an exit, but we also want to be fair to the new investors.' Luna: And that's where a good startup lawyer earns their keep. I've seen terrible cliff language that says 'acceleration upon change of control' without defining 'change of control' — does that include a reverse merger? An asset sale? Lucas: Exactly. Definitions matter. Another common pitfall is the 'double-trigger with a single event' — where the two triggers are compressed into one event, like a stock purchase agreement. That's effectively single-trigger. You need a lawyer who reads the fine print. Luna: Let's talk about the psychology. When you're raising money, everyone's optimistic. No one thinks a co-founder will leave. But the data says about 15 percent of startups experience a co-founder departure within the first two years post-Series A. Lucas: And that number goes up when the market turns. Right now, with growth stocks getting hammered — NVIDIA down 8.5 percent in five days, Microsoft down 9.5 percent — the IPO window is effectively closed for most companies. Founders are under more pressure to perform with less exit optionality. That stress can fracture founding teams. Luna: So what's your practical advice for a founder about to negotiate a Series A term sheet? Where do you start on the cliff? Lucas: First, know your baseline. Standard is four-year vesting, one-year cliff, no acceleration. Then ask yourself: is my co-founder team stable? Are we all committed for the long haul? If yes, you don't need to push hard for acceleration — accept double-trigger and move on. If there's uncertainty, negotiate a modified single-trigger that covers 50 percent of unvested shares upon acquisition, with the rest double-trigger. Luna: And if you're an early employee getting options? Same thinking applies, but the leverage is different. Employees rarely get single-trigger unless they're critical hires. Lucas: True. For employees, the cliff is usually the same, but acceleration is almost never single-trigger. The norm is double-trigger with a good-reason definition. And employees should pay attention to the 'good reason' clause — is it limited to material reduction in salary? Change in location? Title? The narrower the definition, the harder it is to trigger. Luna: I want to circle back to the data point you mentioned earlier — that only 12 percent of Series A term sheets have pure single-trigger. That's from Q4 2025. Is that trend accelerating or slowing in 2026? Lucas: If anything, it's getting tighter. With the market volatility we're seeing this June — ARK Innovation down over 8 percent in five days, growth stocks in a correction — VCs are becoming more conservative. I'd expect that 12 percent to drop below 10 percent by Q3. Founders who insist on single-trigger right now may find themselves priced out. Luna: So the cliff vesting negotiation is really a proxy for how much risk each side is willing to bear. And in a down market, the investor's risk appetite shrinks faster than the founder's. Lucas: Exactly. The best outcome is a term that keeps everyone incentivized — the founder doesn't feel trapped, the investor doesn't feel exposed. That usually means double-trigger with a well-defined good-reason clause and perhaps a partial single-trigger on a portion of shares. It's boring paperwork, but it can save you a lawsuit or a broken cap table. Luna: And if you're a founder reading this — go back to your vesting schedule right now. Do you know what happens if you leave tomorrow? Do your co-founders? If you can't answer in 30 seconds, it's worth a conversation with your lawyer. Lucas: Couldn't agree more. The cliff is not just a piece of legalese — it's the single most important retention mechanism in your company's equity structure. Get it right before the term sheet arrives.
