U.S. seed investment is surging, but with more money going into fewer deals, it’s not altogether surprising that the funding uptick isn’t lifting all startup hubs equally.
Key facts
- New York retained its typical share at around 17%, while Greater Los Angeles and Greater Boston each accounted for about 5% of total funding
- On a dollar basis, the Bay Area captured 45% of U.S. seed funding in 2025, up sharply from 33% in 2024 and 28% in 2023, Crunchbase data shows
- Meanwhile, Greater Los Angeles and Greater Boston have each seen modest declines, falling to about 5% and 4% of seed deal share, respectively
- The Bay Area alone accounted for roughly one-third of all U.S. seed rounds in 2025, up 5 percentage points from the prior year, per Crunchbase data
Summary
In 2025, the Bay Area expanded its dominance of U.S. seed funding, capturing a growing share of both deals and dollars, even as most startups remained geographically dispersed, an analysis of Crunchbase data shows. The result is a more bifurcated landscape: a handful of major hubs, led by San Francisco and New York, pulling in a larger share of capital, while the rest of the country saw its slice shrink. The Greater Los Angeles area and the Greater Boston area are the next-largest hubs for seed investment after the Bay Area and New York, but their share of funding at this stage, as measured by dollars, has dipped 1 or 2 percentage points each since 2024. The Bay Area and New York remain the two central hubs for U.S. startup activity.
