Eiso Kant Kept Asking What Code Could Teach a Machine
Before coding agents became a crowded field, Eiso Kant was already building AI for code. His path through three startups led to Poolside - and to a partnership that began with an acquisition offer he declined.

Jason Warner is the co-founder and CEO of Poolside, a San Francisco-based frontier AI lab building proprietary foundation models for software development with $626M raised and a $3B+ valuation. Before Poolside, he was CTO of GitHub - where he launched Actions, Packages, Codespaces, and incubated what became GitHub Copilot - and then a Managing Director at Redpoint Ventures. A self-described 'average developer but excellent architect,' Warner is betting that reinforcement learning from code execution will make software the first domain where AI surpasses human-level intelligence.
