Browserbase announced a US$40 million Series B led by Notable Capital with CRV and Kleiner Perkins, and launched Director to generate Stagehand automations on Browserbase infrastructure, PR Newswire reported on 17 June 2025.
Browser infrastructure for AI agents is raising growth rounds as models need reliable headless sessions at scale. Buyers still need session isolation, geography options and cost controls on high-volume crawls.
Browserbase sells browser infrastructure plus Stagehand and Director. The release cited more than 50 million sessions in 2025 and named customers including Perplexity, Vercel and Customer.io.
Platform teams should insist on reproducible session and latency tests — before treating any Series B launch as a completed agent-browsing strategy.
