AI's Practical Impact on Building Processes

What does it take to build products that feel thoughtful, emotionally resonant, and unmistakably high-quality, especially inside a company that ships fast and experiments constantly?

In this episode of Supra Insider, Marc and Ben sit down with Nickey Skarstad, Director of Product at Duolingo, to unpack how one of the world’s most beloved consumer apps maintains its bar for craft, clarity, and delight while operating at massive scale. Nickey shares how Duolingo operationalizes quality across teams, how they dogfood relentlessly, and why “unreasonable hospitality” applies just as much to software as it does to service.

She also shares the internal rituals Duolingo uses - like their “hot trash” Friday forum for sharing early experiments, and how these lightweight mechanisms help PMs, designers, and engineers learn from each other. Nickey walks through Duolingo’s product review process, how senior leaders give feedback, and how the company ensures teams move quickly without shipping work that falls below their quality standards.

Whether you’re a PM trying to strengthen your intuition, a design-driven leader aiming for higher quality bars, or a product builder exploring how AI should (and shouldn’t) fit into your workflow, this episode is full of concrete lessons you can use immediately.
