Terms that decide your outcome

Anti-dilution

Protection that adjusts an investor's effective share price if the company later raises at a lower valuation.

Why it matters

It shifts the pain of a down round onto founders and employees. The formula matters enormously, and the difference between the two common versions is severe.

A worked example

Broad-based weighted average adjusts the price partially, in proportion to the size of the new round. A full ratchet reprices all earlier shares to the new lower price, regardless of how small the new round is.

What is typical

Broad-based weighted average is standard and generally acceptable. A full ratchet is aggressive and should be resisted.

Related terms
