Browserbase powers web browsing capabilities for AI agents and applications. We manage headless browser infrastructure for automations that interact with websites, fill out forms, and replicate user actions.
We raised a $40M Series B last year and are continuing to grow, fast. Backed by Kleiner Perkins, CRV, and Notable Capital, our fast-moving team is building on our CEO's founding vision to power the world's best AI tools and help everyone automate the web.
