Browserbase's position is the infrastructure layer underneath other people's agents, providing the headless browser sessions that let an AI agent click, scroll, and fill in real websites at scale, and it has recently extended from raw session infrastructure into a managed agents product built on top of that layer. That positioning matches how it comes up in GTM conversation. It appears as a fixture in practitioner rundowns of the modern automation stack, named alongside the scraping, enrichment, and outbound tools agents get chained together with, and its standing has climbed fast enough to read as one of the default answers to how an agent gets a browser.

Business Profile
Browserbase was founded in January 2024 by solo founder Paul Klein IV, who had previously built Stream Club, a browser livestreaming startup. The company raised $67.5 million across a 2024 seed round, a $21 million Series A, and a $40 million Series B in June 2025 led by Notable Capital, alongside existing backers CRV and Kleiner Perkins, at a $300 million valuation. With 73 employees and $4.4 million in reported 2025 ARR, its customer base spans AI labs like Microsoft and DeepMind and applied GTM and dev-tool teams at Ramp, Amplitude, and Clay, evidence of a company selling infrastructure to both frontier labs and operators building on top of it.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Browserbase's shipped surfaces include a public API and SDK for spinning up browser sessions, plus an MCP server that lets any MCP-compatible agent call a browser directly. That base has extended into a managed Agents product, a single API call that runs a browser agent without separate infrastructure, and into integrations like file handling with Box, letting an agent retrieve, save, and read documents mid-session.
