Founders sign clauses they have never seen before, and only feel them years later at the exit.

A liquidation preference, a broad-based anti-dilution clause, a participating preferred, each one looks harmless on paper and changes your payout completely when the exit lands. TermLab teaches you what each clause means, rates it for founder-friendliness, and simulates the actual pound-for-pound outcome so you know what you are agreeing to before you sign.

How it works

From a wall of legalese to a negotiation checklist in four steps.

1

Orient: the shape of a term sheet

Start with a one-page overview of what a term sheet is, what it is not, and which sections actually matter. TermLab puts the document in context before you look at a single clause.

Learn 13 clauses, each rated green, amber, or red

Each clause gets a plain-English explanation, a real example from an actual term sheet, and a green, amber, or red rating for how founder-friendly it typically is. No legalese.
