Episode No Figma. No Jira. No docs. How Gusto built a new product line with Claude Code | Eddie Kim (CTO)

0:00 51:51

Eddie Kim is the co-founder and CTO of the payroll and HR platform Gusto, which just crossed $1 billion in revenue and serves more than 500,000 small businesses. Recently he did something most CTOs don’t: he went back to writing code. With three other engineers and one designer, Eddie built Gusto Cofounder, a net-new AI product, from zero code to a tier-one launch in 10 weeks. He walks through how that team actually worked, why they threw out nearly every process, and how anyone can copy the approach.

What you’ll learn:

• The trash-can method: how to write, review, and delete a full PR as a product decision instead of a planning doc • The two-tool agent stack behind Gusto Cofounder • The exact “perma-Zoom” setup that replaced standups, retros, and Slack threads for 10 weeks • How a designer with no engineering background hit the 94th percentile for shipping code • The eval-first workflow Eddie uses to fix real customer bugs with Claude Code • How a non-technical leader can prototype an idea to win buy-in, then carry it all the way to production-quality code
