About this episode
Lukas Biewald shares his journey from being a fired CEO to building Weights & Biases, discussing lessons learned and insights on AI and entrepreneurship.
Lukas Biewald has been shaping the future of AI for nearly two decades. In this episode of The Eric Ries Show, we explore how his early passion for the board game Go, his hard-won lessons as a founder, and his focus on alignment and culture helped him build Weights & Biases into a trusted toolmaker in machine learning. In our conversation, we discuss: • Lessons Lukas drew from Go about pattern recognition, persistence, and the power of computation • The hard-won lessons Lukas took from CrowdFlower about timing, focus, and staying in the wrong role too long • How Lukas created his own unpaid internship at OpenAI to sharpen and expand his technical skills • The pain point that inspired Lukas and his cofounders to build Weights & Biases • Practical ways Lukas kept his board aligned • Why caring deeply about your product and users beats clever hacks and pitch decks every time • How W&B’s ‘Year in Review’ showed that delight can be a moat in enterprise software • Why the CoreWeave deal feels fundamentally different for Lukas than the sale of CrowdFlower • And much more! — Where to find Lukas Biewald: • LinkedIn: https://www.linkedin.com/in/lbiewald/ • X: https://x.com/l2k…
