AI isn't just changing the tools designers use. It's changing the way they think, prototype, and build.
In this episode of Design Review, YC Head of Design Eve Bouffard joins General Partner Aaron Epstein to share the AI-first workflow she uses to design products, websites, and events.
Using projects like Paxel, SOTA Zine, and YC Startup School as examples, she explains how coding agents are transforming everything from rapid prototyping and branding to design systems, and why the biggest bottleneck is no longer software. It's imagination.

One of the biggest mistakes founders make is relying on aggregate user metrics instead of understanding how any individuals use their product. In this episode of Startup School, YC General Partner David Lieb walks through one of his favorite tools for better understanding your users, the dot plot. It’s a simple two-dimensional grid that maps individual user activity over time and it can help separate signal from the noise in the early days of a startup. He’ll cover why it gives founders a better sense of product health compared to aggregate metrics, what patterns to look for and real-world examples of how dot plots helped teams at Google Photos and PayPal.

Eddie Kim is the co-founder and Head of Technology at Gusto (W12), a payroll and HR platform serving over 500,000 small businesses in the U.S. that recently crossed $1 billion in annual revenue — with one in five new businesses started today becoming Gusto customers.
Recently, Eddie built Gusto Cofounder, a new AI product that automates recurring business processes end-to-end, all triggered through SMS or Slack without the business owner ever logging in. In this episode of Founder Firesides, Eddie sat down with YC Managing Partner Harj Taggar to explain how he built the first working prototype which was then turned into a shippable product by a team of five people in ten weeks.
