Bridge Round
Quick Definition
A smaller fundraise between major rounds, typically using convertible notes or SAFEs, designed to extend runway until the next priced round.
What Is Bridge Round?
A bridge round is a stop-gap fundraise that "bridges" the gap between two major funding rounds. When a startup needs more cash to reach the milestones necessary for a strong Series A (or B, or C) but isn't ready to raise a full priced round, it raises a bridge — typically $200K to $2M, often from existing investors, using SAFEs or convertible notes.
Bridge rounds happen for various reasons. Maybe you're six months away from hitting the ARR target that would command a strong Series A valuation, but you'll run out of money in three months. Or you had conversations with Series A investors who said, "Come back when you have X." A bridge gives you the runway to get there. Sometimes bridges happen because a planned round fell through or took longer than expected.
The terms of a bridge round depend heavily on context. If existing investors are confident in the company, they might bridge on friendly terms (SAFEs at the previous round's cap). If the company is struggling, bridge terms can be punitive — high valuation caps, warrants, or conversion discounts that reflect the increased risk. Some investors specialize in bridge rounds, and their terms reflect the leverage they have over a cash-strapped company. The ideal bridge is small, fast, and gets you to a position of strength for the next full round.
Why It Matters for Startups
Bridge rounds can be lifelines or warning signs, depending on context. A quick bridge from enthusiastic existing investors is a positive signal — they believe in the company enough to put more money in. A desperate bridge after failing to close a priced round can signal deeper problems. As a founder, understanding bridge dynamics helps you plan your cash management: always start thinking about your next raise when you have 6+ months of runway, not when you're about to run out. Running a bridge from desperation weakens your negotiating position significantly.
Example
Your startup has $300K left in the bank (3 months of runway) and you need to hit $1M ARR to raise a strong Series A — but you're currently at $600K ARR. Your seed investors agree to bridge $500K via SAFEs at the same $8M post-money cap as the seed round. That buys you 5 more months. You hit $1M ARR in month 4, start your Series A process, and close a $6M round at a $25M valuation three months later. The bridge SAFEs convert at the $8M cap, rewarding those investors for the extra risk.
Key Takeaways
- ✅ Bridge rounds provide short-term capital between major funding rounds
- ✅ They're typically structured as SAFEs or convertible notes for speed
- ✅ A bridge from existing investors is usually a positive signal; a desperate bridge is a red flag
- ✅ Plan your runway so bridges are strategic choices, not emergency measures
