117 tech startups tagged "Climate" are currently indexed on techstartupslist.com. This page lists every active match, with logos, taglines, and direct links to each company's site — no paywalled middleman. Notable "Climate" startups in the index include Oklo, 1849 bio, Abatable, Advano, and Aerones. Each profile surfaces team size, founding year, category, and any open roles their careers page is publicly scrapable for. These companies concentrate in Climate, Industrials, and Consumer — the categories where this tag shows up most often in our scrape. Geographically, "Climate" lean toward San Francisco, New York City, and Los Angeles, with the rest spread across remote-first teams and other hubs. Y Combinator batches represented here: W22, S21, W21, and S22, among others. 3% of these companies are hiring right now (4 of 117) — a live signal from the jobs we scrape, not a static directory claim; 1 is currently flagged as trending on hiring momentum; the listing refreshes whenever the scrape runs so tag membership stays current as companies re-tag and new ones appear.
