Bridge Round

Definition

A bridge round is a smaller funding round raised between major priced rounds to extend a company's runway. It is typically structured as a convertible note or SAFE, provides 6-12 months of additional runway, and is often raised from existing investors when the company needs more time to hit milestones for its next major raise.

Overview

A bridge round fills the gap when a startup needs additional capital before it is ready for its next priced round. These rounds are typically $250K to $2M in size and structured as convertible notes or SAFEs with a discount (usually 15–25 %) to the next round's price. The goal is to provide enough runway to hit the milestones that will make the next major fundraise possible at favorable terms.

Common reasons for bridge rounds include: the company is close to key metrics but not quite there (e.g., needing 3 more months to hit $100K MRR for a Series A), market conditions have temporarily worsened making a full round difficult, or the company is pursuing a strategic pivot that needs funding before it can show traction. Existing investors are the most common participants because they already have context and a vested interest in the company's success.

Bridge rounds carry risks for both founders and investors. For founders, bridge capital often comes with higher dilution than a priced round would have, especially if milestones are not met and the next round happens at a lower valuation. For investors, bridge rounds in struggling companies can become "bridges to nowhere." The best practice is to only raise a bridge with a clear, time-bound plan for what milestones the capital will achieve and a realistic path to the next raise.

Example

A startup has $200K in the bank and 2 months of runway but needs 8 more months to reach $1M ARR for a Series A. It raises a $750K bridge via SAFE notes from existing investors at a 20 % discount to the next round, extending runway to 10 months.
