Summary

U.S. seed investment is increasingly concentrating in the San Francisco Bay Area, which captured 45% of U.S. seed funding in 2025, a significant increase from 33% in 2024 and 28% in 2023. This concentration is driven by heavy investment in AI startups. New York maintained its share at approximately 17%, while Greater Los Angeles and Greater Boston each accounted for about 5%. Startups outside these top four metro areas received only 28% of U.S. seed funding in 2025, the lowest share on record. Despite this capital concentration, two-thirds of U.S. seed-stage startups in 2025 were based outside the Bay Area, indicating continued geographical dispersion of startup formation. The Bay Area also accounted for roughly one-third of all U.S. seed rounds in 2025, up 5 percentage points from the prior year, though its median seed round sizes were lower than other major hubs.

Key takeaway

For investors evaluating U.S. seed-stage opportunities, recognize that while the Bay Area dominates in total capital and deal volume, especially for AI, two-thirds of funded startups are still outside this region. Diversify your geographic scouting beyond the top four hubs to capture the long tail of innovation, but be aware that median deal sizes in the Bay Area may be smaller than other major hubs despite its overall funding dominance.

Key insights

U.S. seed funding is centralizing in the Bay Area, particularly for AI, despite broad startup distribution.

Principles

• Capital concentration does not equal startup formation concentration.
• Outlier large rounds skew overall funding distribution.

In practice

• Analyze seed funding without $10M+ rounds for a clearer market view.
