Jason Warner is a former GitHub CTO and Heroku Head of Engineering who now works as a Managing Director at Redpoint, where he evaluates startups' engineering organizations like an insider by assessing code quality, on-call practices, and how engineering teams actually operate day-to-day. He runs a distinctive founder-education content series where he shares tactical advice to technical founders every Tuesday, and later founded Poolside AI, giving him an unusual combination of large-scale engineering leadership, venture investing, and hands-on AI tooling company building experience.

• Commitment to engineering AGI through reinforcement learning. Views RL as the primary vector for scaling intelligence and emphasizes a factory-like approach to large-scale experimentation, believing that all development eventually collapses into the model itself.
• Strict definition of open source AI. Argues that simply releasing downloadable weights does not constitute open source, comparing them to pre-compiled files from the 90s, and insists that the dataset and architecture are the actual source code that matters.
• Macro focus on the three pillars defining the next decade. Identifies energy generation, chip manufacturing for training, and the AI networks themselves as the only three factors that will define the future of digital technology.
• Interest in modernizing legacy infrastructure. Highlights the value of using AI to migrate critical, older codebases—specifically mentioning Ada—into modern languages like Rust to secure and update foundational systems.
• Skepticism regarding innovation at large technology firms. Suggests that once companies reach a certain scale, they lose the ability to build interesting products internally and effectively function as private equity holding companies that must acquire startups to compete.
• Affinity for deep tech culture and sci-fi concepts. Shows a playful side relevant to building rapport, such as discussing simulation theory with his children and referencing frustration with clunky enterprise software login screens during hypothetical space travel scenarios.
