Hi ✌️ I’m Alvaro, the maker of SoCal Foundry. Southern California has an incredible hard tech ecosystem. I built SoCal Foundry to make it easier to see who’s building here and where they’re located. It brings aerospace, defense, energy, robotics, and advanced manufacturing companies together in an interactive map and searchable directory. You can explore by sector, find companies nearby, and submit missing companies or corrections. I’d love your feedback: what would make this more useful for you and which companies should we add next? 🎉
