The Y Combinator W26 batch (Winter 2026) brought 200 tech startups into our index. This page lists every W26 company we currently track, with logos, taglines, and links straight to their own sites — no paywalled middleman. Notable W26 companies include 10x Science, 21st, Aemon, Agentic Fabriq, and Alt-X. Each profile surfaces team size, founding year, location, and open roles when their careers page is publicly scrapable. The W26 cohort skews toward Dev Tools, AI / ML, and Infrastructure — common patterns we see in this batch. Recurring tags across these companies: Artificial Intelligence, AI, B2B, Infrastructure, Enterprise Software. The directory's filter UI accepts any of them as a query. Geographically, the W26 batch we have leans toward San Francisco, Unspecified, and New York City, with the rest spread across remote-first teams and other hubs. and the listing refreshes whenever the scrape runs, so changes propagate without a manual edit.
