Each year, we chart the fifty hardtech companies defining San Diego's technology frontier — the builders working on hard problems in aerospace, defense, autonomy, maritime, and advanced manufacturing. The ecosystem's annual report.
San Diego has quietly become one of the most important hardtech ecosystems in the country — aerospace, defense, autonomy, maritime, biotech, and advanced manufacturing, concentrated in a way few cities can match.
The San Diego Hardtech 50 is our annual attempt to chart it: fifty companies, surveyed and published each year, that represent the frontier of what's being built here. It's not a ranking of who raised the most. It's a map of who's doing the hard, real work — the companies the rest of the ecosystem should know.
It's curated by Rising Tide Partners, published on Substack, and celebrated live with the community.
The full San Diego Hardtech 50 — all fifty companies, with the context on each — lives on the Rising Tide Partners Substack.
