The board seat you gave away too cheap
The Series A lead asked for two seats and an observer. The founder agreed because the round was finally closing. The cost showed up at Series C.
3 seats before, 6 after. That was the board math the founder signed at 11pm on the Thursday his Series A closed, after nine months in a market that had spent the year trying to kill his company. The lead investor had asked for two seats plus an observer right. His counsel called it standard. Exhausted, he deferred, signed, and slept for fourteen hours. He didn't think about the composition again for six months.
By Series C the board had nine seats, six of them investors. The strategic decisions he'd assumed he controlled were, in practice, controlled by an investor majority. When an acquisition offer arrived two years later, the board rejected it over his vote. He'd learned, expensively, that the structure agreed to in one term-sheet meeting was the structure he now lived inside.
Board composition is the most consistently under-negotiated term in venture financing. Founders treat it as procedural because it doesn't touch round mechanics. Investors treat it as foundational because it shapes every decision the company makes afterward. The two sides negotiate different things across the same table, and the founder concedes because he doesn't yet know what he's conceding.
Each investor seat is harder to remove than to grant. Removing a director needs a resignation or a vote, and votes against directors require the kind of conflict that breaks the working relationship the company runs on. Granting the seat takes five minutes. Removing it takes years and trust. That asymmetry is enormous, and founders underweight it every time.
The healthy early-stage board is small and balanced. Five seats. Two founders, one lead investor, two independent directors chosen jointly. The independents are the leverage: obligated to neither side, bringing outside judgment, able to break ties where founder and investor interests split. Most early boards carry zero or one independent, because the slots get eaten by additional investors during the raise. If you took an investor for the brand name, that seat costs the same governance as any other.
The cost of a bad board never shows on a P&L. It shows in the decisions that get vetoed silently. The founder learns which proposals will die at the board and stops bringing them. The board becomes a filter that passes only investor-preferred strategy. The ideas he believed in but couldn't get support for quietly vanish from the deck, the same way a buried metric vanishes from a board update. He ends up running a company he didn't intend to run.
The negotiation that prevents this happens at the term sheet. Instruct the lawyer to fight for board composition with the same intensity as price. Hold out for the smallest board with the most independents. The investor will push back, and the push-back is information. An investor unwilling to accept a balanced board is telling you the governance posture he'll bring for the next five years.
The seat you give away cheap in May is the company you run differently three Novembers later. Negotiate the board before you negotiate yourself.
