Angel Investors in Houston (2026)

404 investors · 404 individual angels · 55% with verified email · 0 claimed profiles

Houston has 404 investors in the Robynhood database, and the number that sets it apart is cleantech and climate at 49 — proportionally one of the highest in the database, and the direct result of an energy industry moving capital into the transition.

Energy money changing direction

49 cleantech investors in a city of 404 is a higher proportion than San Francisco, Boston or New York. These are largely people with oil and gas backgrounds who understand large-scale energy infrastructure and are now funding its replacement.

That expertise is specific and valuable. A climate hardware company will find investors here who can assess an engineering claim, evaluate a plant, and open doors to industrial customers — which very few software-focused climate investors can do.

Healthtech at 71 leads on raw count, supported by the Texas Medical Center, the largest medical complex in the world.

Reach

223 of 404 have a verified email — 55%.

Houston is overlooked by climate founders who default to the Bay Area. That is a mistake if your product touches physical infrastructure.
