The Y Combinator S20 batch (Summer 2020) brought 165 tech startups into our index.

Notable S20 companies include Supabase, Photoroom, adyn, Afriex, and Akiflow. Each profile surfaces team size, founding year, location, and open roles when their careers page is publicly scrapable. The S20 cohort skews toward Healthcare, Dev Tools, and AI / ML — common patterns we see in this batch. Recurring tags across these companies: SaaS, B2B, Fintech, AI, Developer Tools. The directory's filter UI accepts any of them as a query. Geographically, the S20 batch we have leans toward San Francisco, New York City, and London, 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.
