Orange County venture capital & startups
Orange County defense (Anduril / Costa Mesa), medtech, and OC enterprise — not Los Angeles County.
Orange County’s venture gravity is dual-use defense hardware and software (Anduril’s Costa Mesa HQ), plus medtech and OC enterprise/consumer — a SoCal cluster that scouts often mis-bucket as “LA.” As of July 2026 we curate Anduril into this hub (HQ commonly cited as Costa Mesa, CA; JSON lacks hq). No OC-HQ fund profiles in our directory. Founders get an HQ-honest map and a national defense/deep-tech shortlist from real /fund/ pages.
Aliases: orange county, irvine, newport beach, costa mesa, anaheim, huntington beach. Exclude LA County claims (El Segundo, Hawthorne, Santa Monica, City of Los Angeles). Anduril is curated as Costa Mesa / OC — not LA.
