The Y Combinator W24 batch (Winter 2024) brought 230 tech startups into our index. This page lists every W24 company we currently track, with logos, taglines, and links straight to their own sites — no paywalled middleman. Notable W24 companies include Circleback, Legora, 14.ai, Adapted, and Aether. Each profile surfaces team size, founding year, location, and open roles when their careers page is publicly scrapable. The W24 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 W24 batch we have leans toward San Francisco, New York, and New York City, with the rest spread across remote-first teams and other hubs. 2 of these are currently flagged as trending based on momentum signals; and the listing refreshes whenever the scrape runs, so changes propagate without a manual edit.
