Seed funding boom concentrating capital in San Francisco Bay Area

Seed-stage venture funding in the U.S. is experiencing a concentration wave, with increasingly larger portions of capital flowing to startups based in the San Francisco Bay Area. Data from Crunchbase shows Bay Area founders are capturing outsized share of seed rounds as tier-1 VCs tighten sourcing to familiar ecosystems and co-investment networks.

For founders outside SFO, this signals rising difficulty in accessing early-stage capital despite AI's geographic distribution potential. CTOs evaluating vendor strategy should note that innovation bottlenecks may favor entrenched Bay Area players—a long-term competitive advantage for established infrastructure vendors headquartered there.
