About YC S10
The Y Combinator S10 batch (Summer 2010) brought 24 tech startups into our index. This page lists every S10 company we currently track, with logos, taglines, and links straight to their own sites — no paywalled middleman. Notable S10 companies include Docker, PagerDuty, 1000Memories, AdGrok, and AeroFS. Each profile surfaces team size, founding year, location, and open roles when their careers page is publicly scrapable. The S10 cohort skews toward Consumer, Marketing, and Productivity — common patterns we see in this batch. Recurring tags across these companies: Analytics, DevOps, Community, Marketplace, Productivity. The directory's filter UI accepts any of them as a query. Geographically, the S10 batch we have leans toward San Francisco, Mountain View, and Palo Alto, 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.
