This is where we live

We live on 30 acres of forest near the Selkirk Mountains in WA state. Minutes away from the Kalispel Tribe of Indians and only one hour away from the Canadian border.

This is where we live.

Current projects

Open source repos
  • We maintain two popular repos: saas and builderbook.
  • Our repos have >1000 unique visitors per week. Over 100 people sign up on our SaaS Boilerplate demo every week.
  • Our SaaS Boilerplate is the most popular open source React/Next.js/Node.js boilerplate. And it's written with productive TypeScript on both front-end and back-end.
  • We also open-sourced our internal team communication tool, Async, which separates urgent vs. non-urgent conversations.

Software books
  • We wrote and self-published two books at
  • Over three years, we've sold 1000+ copies with less than 3% refund rate.
  • We make twice-a-year upgrades to our books and public repos.

Custom development
  • We've built over a dozen SaaS web applications in the last 10 years for our clients and for ourselves. Each application had multi-server infrastructure supported by lambda functions and numerous third-party APIs.
  • Most of the above SaaS products are built by us from scratch.
  • If you are an individual, startup, or small business in need of a technical team, you will value our expertise.
