Magnus Müller is an entrepreneur and software engineer known as the co-founder and CEO of Browser Use, an open-source framework that enables artificial intelligence agents to control web browsers. The company participated in the Y Combinator Winter 2025 batch and is based in San Francisco.[1]
Career
Müller co-founded Browser Use alongside Gregor Zunic.[2] The company develops an open-source library that allows AI agents to interact with websites by transforming web pages into structured data that language models can interpret and act upon. The project gained rapid traction in the developer community, accumulating approximately 50,000 stars on GitHub within three months of its release.[1]
Browser Use offers both an open-source framework and a commercial cloud API. The company describes its product as providing "agents at scale" with "undetectable browsers," positioning it as an API for automating interactions with any website.[3] The platform has been adopted by teams at a range of technology and enterprise companies, including Airbnb, Amazon, Anthropic, Apple, Google, Meta, Microsoft, OpenAI, Stripe, and others, according to the company's website.[3]
In March 2025, Browser Use raised $17 million in a funding round led by Felicis Ventures, with participation from investors including Y Combinator co-founder Paul Graham. The round attracted attention in part because Browser Use's open-source framework was used by Manus, a prominent AI agent platform.[4][5]
As of early 2026, Müller was reported to be 24 years old and to maintain an intensive work schedule of seven days per week, a practice noted in broader coverage of demanding work cultures at AI startups.[6]
