How agents improve: prompts and knowledge bases

Listen now: Spotify, Apple and YouTube

In the first-ever live recording of Supra Insider, Marc and Ben sat down with Jacob Bank, founder of Relay.app, to unpack one of the most urgent questions facing product leaders today: How do AI agents actually change the way we work? Instead of abstract predictions, Jacob shares the very real workflows, failures, and breakthroughs behind running a 10-person company that delegates work to more than 300 AI agents.

Across the conversation, the three dig into what PMs must learn next: writing job descriptions for agents, architecting responsibilities, managing automated execution, and understanding how agents influence velocity, product quality, and cross-functional collaboration. Jacob also discusses why PMs are lagging behind engineering and ops in adopting agentic workflows, and what will happen to teams who don’t catch up.

If you’re a PM, founder, or operator trying to understand how AI is reshaping product development, or you’ve struggled to translate “agent hype” into concrete, repeatable workflows, this episode gives you a realistic, practitioner-level framework for building with agents today, and preparing for what’s coming next.
