Dianne Penn is Head of Product for Anthropic’s AI Research and Labs teams. She joined in 2023 as Anthropic’s first technical product manager, when the entire product team was five engineers, and has since helped ship every model from Claude 2 through Fable, and helped incubate Claude Code, MCP, Skills, computer use, tool use, and reasoning. Before Anthropic, she helped build Alexa’s AI at Amazon and, before that, traded high-yield bonds at JP Morgan Chase.
In our in-depth conversation, we discuss:
1. What Anthropic’s early days were like
2. The inflection points that turned Anthropic from an underdog into the fastest-growing company in history
3. How exactly Claude got so good at coding
4. The eval-driven development loop her team is pioneering
5. How to find joy in AI when everything is moving this fast
6. Why Claude’s willingness to push back is key to its success
7. Where human judgment remains irreplaceable
