Prototypes as Design Critiques and Review Rituals

Listen now: Spotify, Apple and YouTube

What does “AI-native” actually look like inside a company — not in theory, but in practice?In this episode of Supra Insider, Marc and Ben sit down with James Dillard, former YouTube and Stripe PM, who recently spent three months embedded at Roo Code, an AI-native startup building coding agents that can write and review production code.

James shares what it was like to join a 10-person team where everyone contributes to the codebase — from designers to community managers — and where the product process has been reimagined from the ground up.He walks through how discovery, design, and iteration actually work in an environment where code is the default language of collaboration — and what that means for the future of product management, engineering, and org design.

Whether you’re a product leader trying to make your org more AI-native, a founder exploring new operating models, or just curious about what “AI-native” means beyond the buzzwords — this episode offers a rare inside look at how the next generation of teams are really working.
