Lead investor

The lead investor is the firm that writes the largest check in a round, negotiates the term sheet, and usually takes a board seat — the social proof that anchors the rest of the round.

How it works

Most early-stage rounds need a credible lead before other investors will commit. The lead typically writes 30–60% of the round and signs the first term sheet. Founders should spend most of their fundraising energy securing a lead — once a lead is committed, filling out the rest of the round is much easier. Leads almost always join the board.
