Latest / The Series A Show with Fexingo: Early-Stage Funding, Pitch Decks, and Startup Milestones / The Startup Cap Table Mistake Founders Make Too Late
Transcript
- Lucas: So yesterday I was looking at a cap table from a fintech startup that raised a seed round in 2022. The three co-founders started with thirty-three percent each. By the time they hit their Series B last quarter, the lead founder was down to twelve percent. And the worst part? They did nothing wrong on paper — just standard dilution, standard option pools. Luna: Twelve percent after three rounds? That sounds brutal but honestly not that unusual. Most founders I talk to don't even model their dilution past the seed. Lucas: Exactly. And that's the mistake. They treat each round like a discrete event instead of a multi-year dilution chain. So today I want to walk through how to think about your cap table from day one — specifically, which equity decisions in the first eighteen months determine whether you keep enough control to stay motivated through a Series B or C. Luna: Alright, let's start with the founding team split. Three co-founders each taking a third — that's pretty common. What's the alternative? Lucas: The alternative is to leave room for a lead founder premium. Data from Carta's 2025 equity report shows that startups where the lead founder held at least twenty-five percent going into Series A had a significantly lower rate of founder turnover post-Series B. Not because of voting control — because the psychological ownership stays high enough to weather the slog. Luna: But isn't it hard to justify giving one founder more than others at the very beginning, before anyone's done anything? Lucas: It is, and it can cause friction. But you can structure it with vesting cliffs or performance-based acceleration. The key is to model forward: if you're all equal at the start, and you need a standard option pool of ten percent at seed, plus another ten at Series A, plus typical investor dilution — the lead founder ends up around fifteen percent after Series B. If they started at forty percent, they're closer to twenty-five. That gap is massive in terms of motivation and alignment. Luna: So the fix is to think about the Series B cap table before you issue your first share. That's uncomfortable because at pre-seed you don't even know if you'll get to seed. Lucas: Right, but you can build in flexibility. Use a vesting schedule that allows reallocation if someone underperforms. Set aside a founder option pool. I'm not saying lock in a forty percent split day one. I'm saying don't lock in a third each without asking what that means if everything goes right. Luna: What about the first three hires? That's another place founders give away equity too fast. Lucas: That's the second biggest trap. A lot of founders give their first engineer one to two percent as an incentive. But if you're pre-seed, that first engineer might not even be the key person who takes you to product-market fit. I've seen founders hand out two percent to someone who leaves after eight months. That equity doesn't come back. Luna: What's the right number then? I've heard one percent for early engineers is standard. Lucas: It depends on stage and cash. If you're paying below market, you need more equity to compensate. But the framework I like is: for the first three hires, allocate no more than three percent total, with heavy vesting — four-year standard, one-year cliff. And make sure any unvested shares from departures go back into the option pool, not to the company treasury. That way you don't get dilution without the benefit. Luna: And advisors? That's another landmine. I've seen a founder give ten percent to a 'strategic advisor' who ended up being useless. Lucas: Ten percent is insane. Standard advisor grants are zero point two five to zero point five percent, with one-year vesting and no cliff. Anything above one percent should require board approval and a specific milestone. The cap table is like a budget — every percentage point has a future cost. Giving away two percent to an advisor might cost you two million dollars at exit. Luna: Let's talk about the option pool itself. How do you size it so it doesn't nuke the founders? Lucas: The standard practice is to create the option pool before the priced round, so the dilution hits only the common shareholders — the founders and employees. VCs want it that way because it means they don't get diluted. But founders can negotiate to have the pool created after the round, so the dilution is shared. It's a small thing that can save founders five to ten percent dilution at Series A. Luna: I remember reading a Y Combinator post that said most startups create a ten percent pool at seed. That's reasonable? Lucas: For seed, ten percent is standard. But you have to model how many hires that covers. If you're planning to hire ten people before Series A, ten percent might be tight. Better to create a slightly larger pool upfront than to expand it later and take another dilution hit. And always use a rolling pool — meaning unissued options stay in the pool instead of expiring. Luna: One thing that's come up a lot in 2026 is the use of rolling valuations. We've covered that before. But does that affect how you think about the cap table? Lucas: It does, because rolling valuations mean the price per share changes over the fundraising process. If you're doing a rolling close, you might have multiple investors at different prices. That can create complexity in the cap table with different series and conversion rights. Founders need to track this carefully or they end up with a cap table that's impossible to read, which scares off later investors. Luna: So keep it clean. Don't do a rolling close with five different prices if you can avoid it. Lucas: Exactly. Or if you do, use a simple SAFE that converts at a discount to the next round. That keeps the cap table clean until the priced round. Luna: Alright, I think we've covered the biggest mistakes. Let's tie it together: what's the one thing a founder should do today to protect their cap table? Lucas: Model your dilution through Series B. It's a thirty-minute exercise in a spreadsheet. Put in your current ownership, your option pool, your expected round sizes, and typical investor ownership targets. See where you end up. If you're below fifteen percent as a founder after Series B, rethink your equity allocation now. Luna: Good advice. And if you want to run that model, there are free templates from Carta and Pulley. Lucas: And if today was actually useful to you, the way these stay ad-free is listener support. You can find us at buy me a coffee dot com slash fexingo. It's a small way to keep these conversations going without sponsors. Luna: Yeah, it really helps. We put a lot of work into making these practical, and knowing it's useful to you makes it worth it. Lucas: Alright, let's wrap with one more specific example. I saw a startup this week that had a catastrophic cap table problem — they had issued warrants to an early vendor that gave them conversion rights at a massive discount. That blew up their Series A negotiation because the investors saw that and demanded a lower valuation to compensate. Luna: Warrants to a vendor? That's unusual. But it shows how anything with a conversion feature can poison a round. Lucas: Right. So the rule is: avoid complexity. Use standard instruments — common stock, standard option pools, simple SAFEs. Anything exotic should be scrutinized by a lawyer who specializes in startup equity, not your cousin who does real estate. Luna: Good note. Thanks Lucas. That's it for episode 50 of The Series A Show.
