Bridge Round

Also called Bridge Financing, Bridge Loan, and Seed Extension

A smaller raise between two main rounds, meant to extend runway until a larger round or a milestone. Often done on a SAFE or note from existing investors.

Why it matters

A bridge can be a lifeline to reach the metrics a bigger round needs, or a warning sign that the last round did not go far enough. Investors read which one it is closely.

For example

Six months short of the metrics a Series A needs, a startup raises a 5 crore bridge on a SAFE from its existing seed investors to reach them.

It shows you the exact founder behavior that reads as opportunity versus desperation. Open saastr.com →
