E192: Creating Browser Use, Navigating Hyper Growth & Building in the Competitive Browser Automation Space

Author: Robby (MTF); Tim (Essence VC) February 18, 2026 Duration: 41:13

In our latest Open Source Startup Podcast episode, co-hosts Robby and Tim talk with Magnus Müller, the Co-Founder & CEO of Browser Use - the platform that makes web agents come to life. Their open source, browser-use, has almost 80K stars on GitHub and is widely adopted.

This episode dives into the unexpected rise of an open-source browser automation project that took off during Y Combinator - while many similar projects before and after it never gained traction. The founder reflects on why: delivering a “magical moment” fast. Early demos showing AI controlling a browser, inspired by trends like OpenAI’s Operator, and immediately clicked with people. What began as a developer-only Python library evolved into a hosted product as non-technical users - from sales teams to startups - wanted access.

Along the way, the team leaned into controversial but compelling use cases, like AI applying for jobs on your behalf, which sparked conversation and accelerated growth. The core challenge they focused on solving was reliability: unlike deterministic automation scripts, AI agents can behave unpredictably, making trust and repeatability central problems to overcome.

The long-term vision goes beyond UI automation toward agents that can skip the browser entirely and interact directly with website servers through structured actions. But the conversation isn’t just about infrastructure. The founder admits that early growth came mostly from building and talking to users, while recent months have been dedicated to storytelling and marketing rather than coding. A personal through-line emerges as well: learning to replace defensiveness with curiosity - questioning assumptions, staying open to feedback, and continuously refining both the technology and the narrative around it.


Building a company around open source software is a unique and often misunderstood path, full of specific challenges and rare opportunities. The Open Source Startup Podcast digs into that journey directly with the people who have navigated it, moving beyond theory to the practical realities shared in conversation. Hosts Robby and Tim bring their distinct perspectives from MTF and Essence VC to these discussions, creating a space where founders speak candidly. You’ll hear from the architects behind names like HashiCorp, MongoDB, and Vercel, as well as leaders from Chronosphere, DBT, and mobile.dev, as they unpack their experiences. This podcast focuses on the pivotal decisions around community building, monetization strategies, and maintaining project ethos under the pressures of scaling a business. Each episode serves as a detailed case study, revealing how these companies turned publicly available code into sustainable, impactful enterprises. The dialogue naturally explores the tensions between open collaboration and commercial needs, offering a real-world blueprint that is both instructive and nuanced. For anyone curious about the intersection of community-driven development and venture-scale growth, this series provides an essential and unfiltered resource.
