Episode notes
Power of Agentic AI Workflows
- Agentic AI workflows improve results by iteratively planning and revising outputs.
- Linear prompt-response models perform worse without the ability to research and revise.
Focus on Concrete Product Ideas
- Pursue concrete product ideas to give engineers clear directions and speed up development.
- Avoid vague ideas like 'optimize healthcare assets' which lead to slow, unfocused builds.
Leverage AI for Faster Prototyping
- Use AI coding assistance to rapidly iterate and build prototypes ten times faster.
- Write quick, insecure prototypes initially and improve security before shipping.
