Notable W25 companies include AfterQuery, 10x, a0.dev, A1Zap by A1Base, and Adam. Each profile surfaces team size, founding year, location, and open roles when their careers page is publicly scrapable. The W25 cohort skews toward AI / ML, Dev Tools, and Fintech — common patterns we see in this batch. Recurring tags across these companies: Artificial Intelligence, AI, B2B, SaaS, Generative AI. The directory's filter UI accepts any of them as a query. Geographically, the W25 batch we have leans toward San Francisco, New York City, and London, with the rest spread across remote-first teams and other hubs. 1 of these is currently flagged as trending based on momentum signals; and the listing refreshes whenever the scrape runs, so changes propagate without a manual edit.
