Real Estate & Construction startups in Southern California

Property technology, construction tech, and real estate services.

Strata Millenia, Maui Business Park, and Astera are the best-funded proptech and construction-tech companies here so far, spread across San Diego, Newport Beach, and Long Beach. It's a smaller category than B2B or industrials, but one tied directly to Southern California's ongoing housing and infrastructure needs.
