The Velocity Lab

Dave and Dan tell the App Vitals origin story: the 37signals build-for-yourself philosophy, how a side project became Shipwright (their open-source Devin alternative), and why test readiness is the on-ramp to autonomous coding.

Show Notes

Episode Summary

Dave and Dan tell the origin story of App Vitals — from LiveKit AI-voice tutorials to an AI-transformation consultancy to shipping their own open-source autonomous coding agent. They unpack the 37signals philosophy that shapes how they build, how a mobile-dev side project quietly became Shipwright, and why test readiness is the real on-ramp to autonomous programming.

Key Topics

  • The 37signals model — build products for yourselves first, let consulting pay the bills
  • How Shipwright started as a Claude Code plugin and grew into a managed autonomous coding agent
  • Shipwright vs. Devin — open source, runs in your own infrastructure, fully customizable vs. a closed SaaS black box
  • Coding asynchronously in Slack: planning and reviewing while the agent handles execution, PRs, review, and deploy
  • The ski-trip story — building and deploying a website by voice from a chairlift, no laptop
  • Test readiness as Phase Zero: fixing flaky, slow, low-coverage tests before you can trust an agent to ship

Notable Quotes

  • "There's no reason to be in a terminal. There's no reason to write code anymore."
  • "While I was skiing, it built a different version of solitaire and deployed it to Vercel — and I never saw my laptop the whole day."
  • "We ship hundreds of PRs a week for us and our clients with no human interaction."
