Custom builds

Have a process that eats hours every week? We design and build web, mobile and AI-powered software for businesses, including integrations with the systems you already run.

The studio comes from an operations background, so we start from how the work actually gets done and build the smallest tool that fixes it.

How we work

  • One job per toolEach tool does one thing well, with no accounts, sign-ups or clutter.
  • Sources shownNumbers come from primary sources such as the CDC, the NIH and government emission data, and we link them.
  • Quiet by designFast static pages that work without a login and stay out of the way.
