About YC W23
The Y Combinator W23 batch (Winter 2023) brought 241 tech startups into our index. This page lists every W23 company we currently track, with logos, taglines, and links straight to their own sites — no paywalled middleman. Notable W23 companies include Resend, Avoca, Finni Health, Nango, and Vitalize. Each profile surfaces team size, founding year, location, and open roles when their careers page is publicly scrapable. The W23 cohort skews toward AI / ML, Dev Tools, and Fintech — common patterns we see in this batch. Recurring tags across these companies: B2B, SaaS, AI, Artificial Intelligence, Generative AI. The directory's filter UI accepts any of them as a query. Geographically, the W23 batch we have leans toward San Francisco, New York City, and Remote, with the rest spread across remote-first teams and other hubs. 4 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.
