Top Climate Startups in 2026

Climate tech, energy, agriculture, and sustainability startups

Last updated

2026-07-17

The Climate category collects 172 tech startups indexed on techstartupslist.com. Climate tech, energy, agriculture, and sustainability startups. Notable companies in this space include 1849 bio, Abatable, Advano, Aerones, and AirMyne — each profile links to the company's own site, lists open roles when their careers page is scrapable, and surfaces team size, founding year, and category tags. Common themes across these Climate startups: Climate, Energy, ClimateTech, Agriculture, Hard Tech. Filtering by any of these tags in the directory narrows the list further. Geographically, the Climate index leans toward San Francisco, Los Angeles and London, with the rest spread across remote-first teams and other hubs. Many of these companies came in through the Y Combinator scrape (batches F25, S14, S15, S16); 1 is currently flagged as trending based on recent momentum signals; and the index refreshes daily so this page stays current as funding rounds close, jobs open, and new entrants ship. For a broader view, see the full directory or jump to Climate jobs to apply directly — every outbound link goes to the company's own site, not a paywalled middleman.
