How to raise at Series B

Build the financial model in their format

Series B funds want a financial model that maps to their underwriting framework — magic number, payback period, gross margin path, NRR. Default to the format they request in diligence.

Anchor on a single bet

Series B is when 'we do everything' kills the round. Pick the bet, build the next 18 months around it, name it explicitly.
