About YC W18
The Y Combinator W18 batch (Winter 2018) brought 110 tech startups into our index. This page lists every W18 company we currently track, with logos, taglines, and links straight to their own sites — no paywalled middleman. Notable W18 companies include Replit, Simetrik, Vanta, Veriff, and Acely. Each profile surfaces team size, founding year, location, and open roles when their careers page is publicly scrapable. The W18 cohort skews toward Healthcare, Consumer, and Dev Tools — common patterns we see in this batch. Recurring tags across these companies: SaaS, Fintech, B2B, Artificial Intelligence, Consumer. The directory's filter UI accepts any of them as a query. Geographically, the W18 batch we have leans toward San Francisco, New York City, and Toronto, 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.
