Third Stone Software

We build the software that moves your business forward.

Third Stone Software is a software development and contracting studio. From a napkin sketch to a production system serving real users, we design, build, ship, and support custom applications — web platforms, mobile apps, cloud back ends, and AI-powered features that would have been impossible a year ago.

We're small, senior, and hands-on. That means you work directly with the people writing your code — no layers, no hand-offs, no surprises. Whether you need a product built end to end or an experienced team to augment your own, we plug in fast and deliver.

And we practice what we pitch: our own products — from kindjams, a live-music streaming platform, to nDurance, an AI endurance coach — run on the same modern stack we bring to every client.

What we do:

  • Custom web application development
  • Mobile app development
  • Cloud architecture & deployment on AWS
  • AI & LLM integration
  • API design & systems integration
  • Contract development & team augmentation
  • Technical consulting & architecture reviews
  • Ongoing maintenance, hosting & support
