How much equity for employee option pool is a question worth asking before the term sheet, not after. The pool a VC carves out pre-money is where founders quietly lose the most equity, and most never notice until it's already signed.
You're three weeks into term sheet negotiations and a number just showed up on page two that wasn't there before: a 15 percent employee option pool, created before the new money comes in. Nobody explained it on the call. It just sits there, folded into the pre-money valuation, quietly doing the one thing every founder googling how much equity for employee option pool is trying to avoid: shrinking your stake without touching the headline price.
Here's the mechanic. A VC offers you an $8 million pre-money valuation on a $2 million raise. Sounds clean, $10 million post-money, they own 20 percent. But the term sheet also asks you to carve a 15 percent option pool out of that $8 million, before the round prices. That pool isn't free. It comes entirely out of your side of the cap table and the founding team's, not the investor's. Your real, effective pre-money number just dropped to something closer to $6.8 million, and the investor's 20 percent stays exactly where they wanted it. You took the entire hit for a pool of shares that hasn't even been granted to anyone yet.
Run the same round in actual share counts and it gets sharper. Say your company has 8,000,000 fully diluted shares outstanding before any of this, all held by founders and early team. Without a pool shuffle, a $2 million check on an $8 million pre-money simply adds 2,000,000 new investor shares to reach a 10,000,000 share post-money cap table, and you're still holding 80 percent. Add a 15 percent pre-money pool into that same negotiation and the total share count has to grow to roughly 12,300,000 to make the math work: the investor still takes their 20 percent, the pool takes its 15 percent, and your 8,000,000 shares, unchanged in number, now represent 65 percent instead of 80. Nobody touched your shares. Your ownership dropped 15 points anyway, because you're the only one who didn't get new shares to compensate.
Fred Wilson has been writing about this on his AVC blog for close to two decades, and he calls it exactly what it is: a way for investors to get a cheaper price without lowering the valuation they'll tell the next round about. The trick works because most founders are staring at the valuation number and the ownership percentage, and nobody is staring at where the option pool sits in the stack. It sits pre-money. That's the whole shuffle.
There's no single right number, but there is a real range, and Carta's own equity data gives you the actual market rather than a rule of thumb. At seed, pools tend to sit around 12 to 13 percent of the fully diluted cap table. By Series A, investors typically push for a refresh that brings the total pool to somewhere between 15 and 20 percent, and founder ownership after that round commonly lands in the 35 to 42 percent range once the earlier seed dilution and the new pool are both accounted for. Series B and beyond, pools usually shrink back down to 5 to 8 percent, because by then the org chart is mostly built and you're not hiring six VPs and a head of sales all at once.
Those numbers matter because they give you a benchmark to argue from. If a Series A term sheet is asking for a 20 percent pool and your actual hiring plan for the next 18 months only needs 12, you have a specific, defensible number to counter with, not a vague objection that you'd rather keep more equity.
Size the startup option pool to your hiring plan, not their template
The right way to set the number is to build it bottom up. Take your actual hiring plan for the next 12 to 18 months: the VP of Engineering, the two senior engineers, the first AE, whatever roles are actually on your roadmap. Price each one at the equity grant level your target candidates will expect, add it up, and that total is your pool. Not 15 percent because that's what the template says. Not 20 percent because the investor's lawyer always asks for 20 percent. Your number.
Do this exercise before you're in the term sheet conversation, not during it. A founder who walks in with a hiring plan and a pool size derived from it is negotiating from a spreadsheet. A founder who's never run the math is negotiating from a gut feeling, and gut feelings lose to a VC associate who does this math for a living every week.
Push the option pool shuffle to post-money, or split the difference
Y Combinator's guidance to founders is blunt about this: whenever you can, negotiate for the option pool to be created or topped up post-money, after the new investor's check is in, so the dilution gets shared across the whole new cap table instead of landing entirely on the founders. That single change, pre-money versus post-money, can be worth several percentage points of your company, and it costs the investor nothing they weren't already getting. They still end up owning the same slice of a real company. You just stop being the only one who pays for a pool that benefits everyone at the table, including them.
If a VC won't budge on pre-money entirely, there's a middle position worth trying: shrink the pool itself. A 20 percent ask built on generic assumptions can often come down to 12 or 13 percent once you show your actual hiring plan and headcount timeline. You're fighting over a number now, and numbers you can win with math.
Timing matters here too. Raise this in the first term sheet call, not after you've verbally agreed to headline terms and everyone's waiting on lawyers to paper it up. Once the valuation and the pool size have both been said out loud and nodded at, walking it back reads as reneging even when you're only correcting something that was never explained to you in the first place.
The unallocated employee equity pool percentage nobody mentions
There's a second trap hiding in the same conversation, and it's one that Carta has flagged repeatedly in its own equity reports: unallocated shares sitting in the pool between rounds get treated as belonging to nobody, but they still count against the fully diluted share count every time someone calculates ownership percentage. A pool that's sized too large and never gets granted out doesn't sit there harmlessly. It drags down everyone's stated ownership, founders included, on every cap table pull until those shares actually go to an employee or get returned to the pool. An oversized pool isn't a cushion. It's a liability sitting on your table until you either hire into it or negotiate it back down at the next round.
That's the argument for sizing an ESOP for startups tight and refreshing it at each subsequent round rather than front-loading a huge buffer at seed to avoid the conversation later. You'll have the conversation either way. The only question is whether you have it once, with real numbers, or repeatedly, as a hidden tax nobody flagged until a lawyer walked you through the fully diluted math.
None of this is complicated once you see it laid out. It's arithmetic dressed up as a valuation term, and the founders who avoid getting shuffled are the ones who show up with their own hiring plan and their own number, and simply refuse to let the term sheet's default become their default.
