Bridge rounds were supposed to be rare exceptions. Now they’re standard practice, with 42% of seed companies raising extensions. Each round adds 8-12% dilution, destroys cap table cleanliness, and signals weakness to Series A investors. What founders believe extends runway actually accelerates the path to acqui-hire or shutdown.
10 KEY TAKEAWAYS: THE BRIDGE ROUND EPIDEMIC
42% raise multiple seed rounds: Nearly half of seed-stage companies now execute seed extensions, pre-seed, seed, seed-plus, seed-2 structures before attempting Series A.
Each extension adds 8-12% dilution: Bridge rounds consume 15-25% total founder equity before Series A, leaving insufficient ownership to maintain motivation through exit.
Bridge rounds signal distress, not strength: Series A investors interpret multiple seed rounds as inability to hit milestones, not capital efficiency or strategic patience.
The orphaned company phenomenon: Companies achieving $500K to 1M ARR exist in purgatory, too successful to die but not exciting enough for institutional Series A.
Valuation stagnation becomes inevitable: Bridge rounds at flat or down valuations destroy the step-up narrative essential for attracting growth-stage capital.
Cap table complexity explodes: Multiple seed rounds create 15-25 investors on the cap table before Series A, creating governance nightmares and signaling problems.
Founder salary compression extends: Each bridge round resets the clock on below-market compensation, burning personal savings and opportunity cost for years longer.
The correlation paradox intensifies: Companies that execute perfectly on bridged timelines find goalposts moved again, as investors discount even strong metrics.
Acqui-hire becomes the likely exit: Big Tech targets companies at 18-30 months post-seed when teams are strong but momentum stalled, delivering 3x instead of 20x returns.
Alternative structures become essential: The multi-round seed trap proves traditional equity dilution can’t accommodate the extended timelines modern ventures require.

The Bridge Round Epidemic: When Extensions Become Quicksand
In venture capital’s golden age (2015-2020), bridge rounds were exceptional events signaling either unexpected opportunity or concerning distress. Approximately 15-20% of seed-stage companies raised extensions, and those that did faced significant stigma in subsequent fundraising conversations.
That world no longer exists.
Current data shows 42% of seed-stage companies now raise at least one extension round (seed-plus, seed-2, or similar structure) before attempting Series A. In certain sectors like B2B SaaS and deep tech, the percentage exceeds 55%. What was once the exception became the majority pattern.
This shift represents more than changing terminology. It reflects a fundamental breakdown in the seed-to-Series-A financing model that creates cascading problems for founders, investors, and the broader ecosystem.
The Anatomy of a Multi-Round Seed Journey
Let’s trace the typical path of a company caught in the multi-round seed trap, using realistic numbers based on current market data:
Month 0-6: Initial Seed Round (The Optimistic Beginning)
Company: B2B SaaS startup with strong founding team from tier-one tech companies Round: $3M seed at $12M post-money valuation Investors: Lead investor commits $2M, syndicate fills remaining $1M across 5 angels Metrics at raise: $50K ARR, strong product-market fit signals Founder equity remaining: 75% (25% dilution including option pool) Plan: Reach $2M ARR in 18 months, raise $8M Series A at $25M post
Everything feels achievable. The team executes well. Product development stays on track. Early customers validate the vision.
Month 6-18: The Grind (Slower Than Expected)
Actual progress:
Month 6: $200K ARR (vs. $300K planned)
Month 12: $600K ARR (vs. $1M planned)
Month 18: $1.1M ARR (vs. $2M planned)
The company grew 22x in 18 months, a genuinely strong performance. But they’re 45% below plan. Customer acquisition cost ran higher than modeled. Sales cycles stretched longer than enterprise software veterans predicted. Technical debt accumulated faster than anticipated.
