Make a table of the top 12 US startup hubs with their strengths and weaknesses.

ChatGPT

Below is a practical 2026-oriented ranking of 12 major U.S. startup hubs. There isn't one definitive ranking, so I've weighted venture-capital access, founder/talent density, research institutions, startup activity, exits, and sector depth. Current ecosystem data strongly supports the Bay Area as a category of its own: Carta puts it alone in Tier 1 for early-stage capital, while New York, Boston, and Los Angeles form Tier 2.

Perplexity

The “best” U.S. startup hub depends heavily on your company’s sector, capital needs, and hiring model—not simply on a citywide rank. The table below selects 12 ecosystems with durable startup density, access to specialized talent and capital, and distinctive industry advantages; it is not a cost-of-doing-business ranking. The Bay Area and New York remain the broadest capital-and-customer markets, while places such as Boston, San Diego, and Research Triangle are especially compelling for science-based companies.
