B2B startups in Southern California
Business software and services sold to other companies. The largest single category of startup across Southern California, spanning sales tools, vertical operating systems, and everything in between.
It's the largest category here by far, and one of the most varied — the best-funded names span Shield AI's defense-focused autonomy software in San Diego, Metropolis Technologies' AI-powered parking infrastructure in Santa Monica, and Impulse Space's in-space transportation services in El Segundo. What ties them together isn't a shared product category, just a shared buyer: another business, not a consumer.
