The Y Combinator W19 batch (Winter 2019) brought 155 tech startups into our index. This page lists every W19 company we currently track, with logos, taglines, and links straight to their own sites — no paywalled middleman. Notable W19 companies include Linear, Alpaca, Ashby, 1910, and Accept.inc (formerly BoardRE). Each profile surfaces team size, founding year, location, and open roles when their careers page is publicly scrapable. The W19 cohort skews toward Dev Tools, Consumer, and Fintech — common patterns we see in this batch. Recurring tags across these companies: SaaS, B2B, Fintech, Developer Tools, Artificial Intelligence. The directory's filter UI accepts any of them as a query. Geographically, the W19 batch we have leans toward San Francisco, Boston, 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.
