Fundraising
Bridge Round
Quick definition
A small interim financing (often a SAFE or note extension) raised to extend runway between two priced rounds.
Bridge rounds typically happen when a startup needs more runway than its last priced round provided but isn't ready (or able) to raise the next priced round. Usually done as SAFEs or convertible notes from existing investors. Bridge-to-Series-A is the most common variant. A 'bridge to nowhere' is a bridge that doesn't lead to a clean next round — usually a bad sign.
