The Y Combinator S24 batch (Summer 2024) brought 247 tech startups into our index. This page lists every S24 company we currently track, with logos, taglines, and links straight to their own sites — no paywalled middleman. Notable S24 companies include Simple AI, &AI, 1849 bio, Abel Police, and ACX. Each profile surfaces team size, founding year, location, and open roles when their careers page is publicly scrapable. The S24 cohort skews toward AI / ML, Dev Tools, and Healthcare — common patterns we see in this batch. Recurring tags across these companies: AI, Artificial Intelligence, B2B, SaaS, Developer Tools. The directory's filter UI accepts any of them as a query. Geographically, the S24 batch we have leans toward San Francisco, New York City, and London, with the rest spread across remote-first teams and other hubs. 1 of these is currently flagged as trending based on momentum signals; and the listing refreshes whenever the scrape runs, so changes propagate without a manual edit.
