The Y Combinator S20 batch (Summer 2020) brought 165 tech startups into our index. This page lists every S20 company we currently track, with logos, taglines, and links straight to their own sites — no paywalled middleman. Notable S20 companies include Supabase, Photoroom, Taktile, adyn, and Afriex. Each profile surfaces team size, founding year, location, and open roles when their careers page is publicly scrapable. The S20 cohort skews toward Healthcare, AI / ML, and Dev Tools — common patterns we see in this batch. Recurring tags across these companies: SaaS, B2B, Fintech, Developer Tools, AI. The directory's filter UI accepts any of them as a query. Geographically, the S20 batch we have leans toward San Francisco, New York, and London, with the rest spread across remote-first teams and other hubs. 3 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.
