A studio for software that has to hold weight.
Stonearc is a senior, Fort Worth · Dallas, Texas-based studio. We design and build the load-bearing software, CRM, and AI that growing companies actually run on.

I’ve seen what slow software failure costs. So I build against it.
Most business software doesn’t fail in a crash. It fails slowly — a spreadsheet that quietly became load-bearing, an integration nobody documented, an AI experiment that turned into tech debt. It’s fine until the day it isn’t.
Stonearc exists to build the other kind: systems engineered like an arch, where every piece is designed to carry the next, and the keystone locks it together. Senior people, fixed scope, built to still be worth running long after launch.
An arch holds because every stone is engineered to carry the next.
Roman arches still stand after two thousand years because the load is designed, not hoped for. We build software the same way — foundations first, a keystone that locks the system together, and structure that carries real business weight without cracking.
Foundations
We map how your business actually runs before writing a line of code. The base is right, or nothing on top of it is.
The keystone
Every system has one component everything else leans on. We engineer that piece first, and lock the rest to it.
Load-bearing
Built by senior engineers to be maintained, extended, and trusted in five years — not rewritten next quarter.
Senior hands only
The people who scope your work build it. No junior bait-and-switch, no offshore handoff.
Fixed scope, real numbers
You know the price and the plan before we start. No open-ended meters running in the background.
Maintainable by design
We optimize for the version of your software that has to keep running in five years — not the demo.
Production over pilots
Especially with AI: we ship things that survive contact with real data, or we tell you not to build them.
