The Y Combinator W09 batch (Winter 2009) brought 7 tech startups into our index. This page lists every W09 company we currently track, with logos, taglines, and links straight to their own sites — no paywalled middleman. Notable W09 companies include Airbnb, Cloudkick, Divvyshot, Echodio, and Heyzap. Each profile surfaces team size, founding year, location, and open roles when their careers page is publicly scrapable. The W09 cohort skews toward Consumer, Infrastructure, and Productivity — common patterns we see in this batch. Recurring tags across these companies: Marketplace, Travel, Music, Advertising, Email. The directory's filter UI accepts any of them as a query. Geographically, the W09 batch we have leans toward San Francisco, CA, and Atlanta, 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.
