Open Source Startup Podcast

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.

In our latest Open Source Startup Podcast episode, co-hosts Robby and Tim talk with Catherine Jue, Co-Founder and CEO of browser infrastructure company Kernel. Their open source images acts as a browsers-as-a-service for automations and web agents.
In this episode, we break down what Kernel is building today and why browser infrastructure has quietly become one of the most important layers for AI agents. We talk about Kernel’s focus on fast, low-latency cloud browsers, why performance matters more than people expect, and how developers can connect agents via APIs or MCP servers without spinning up heavy infrastructure themselves.
We also explore the real-world use cases driving adoption - from a new wave of RPA for industries without APIs, to real-time web analysis, sales intelligence, and voice agents that need to respond instantly. Finally, we dig into Kernel’s open-source, developer-first DNA, the technical bets behind its control plane and unikernel-based browsers, and why the team believes agentic workflows are still early, but inevitable.

In our latest episode, co-hosts Robby and Tim talk with Robert Brennan, Co-Founder & CEO of OpenHands - the open platform for cloud coding agents. Their open source project, also called OpenHands, has 67K starts on GitHub and provides a software agent SDK, CLI, and local GUI. They also have OpenHands cloud - their paid, hosted version of the OpenHands GUI.
This episode traces the rise of OpenDevin - now OpenHands - as an open-source alternative to closed AI coding agents like Devin. Open to anyone from day one, it attracted highly technical developers, academics, and eventually large enterprises that valued flexibility, privacy, and lack of model lock-in.
Launched amid the 2024 surge of excitement around autonomous coding agents, OpenHands quickly built a massive community and differentiated itself by rejecting the idea of replacing engineers, instead focusing on empowering them through transparent, human-in-the-loop tooling.
The discussion also covers the fragmented AI dev-tool landscape and why open source may define future standards. While many tools compete in the individual “inner loop” of coding, OpenHands emphasizes the collaborative “outer loop,” safety, and running agents at scale. Its organic growth, community-driven roadmap, and focus on real developer pain points highlight a future where AI accelerates software creation without removing human accountability.

In our latest episode, co-hosts Robby and Tim talk with Julien Mangeard, Co-Founder of open source backup platform Plakar. Plakar's open source, also called plakar, has 1.5K stars on GitHub and provides a backup solution powered by open source, immutable data store Kloset.
The podcast discusses why data backup remains a critical but unsolved problem, especially as the number of data sources has exploded across SaaS applications, cloud databases, and on-prem systems. For CISOs and CTOs, this complexity makes it increasingly difficult to ensure everything is done “the right way.” The core argument is that the only truly safe approach is maintaining an independent, secure copy of your data - without vendor lock-in and with guaranteed long-term access, sometimes for decades. End-to-end encryption, immutable storage, and compatibility with different storage backends are emphasized as essential foundations rather than optional features.
The conversation contrasts hype-driven cloud-only backup companies like Eon with Plakar’s back-to-basics approach: an open source, resilience-focused system designed to handle large and diverse datasets securely. Built around an immutable storage engine (Kloset), Plakar aims to let individuals or small teams manage their own backups while also supporting collaboration at scale. The founder’s motivation is rooted in personal experience- having previously lost critical data as a CTO - which reinforced the need for security, openness, and community involvement to continuously add and validate new data sources in a rapidly evolving data landscape.

In our latest episode, co-hosts Robby and Tim talk with Zarko Milosevic (CTO) & Arianne Flemming (COO) of Informal Systems. They've built a protocol design & cross-chain infrastructure platform to foster trust in software and money.
This episode explores how open source infrastructure and security drive company-building in high-stakes financial software. Using Malachite - a consensus engine built for a customer and later acquired by Circle - as an example, the conversation highlights how verifiability and reliability are core to the team’s approach.
Informal operates in a unique way. They have core products and ones that are spun out. Projects emerge organically from real user needs and are either kept in the core or spun out as independent companies, often as open source software with services. With a worker-owned structure and roots in crypto, the organization focuses on building trustworthy financial and software infrastructure while staying flexible through spin-outs and acquisitions.
