Polymath Industrial is a Montana-based engineering shop building hardware, firmware, and software for the people who run the world's machines.
Most industrial problems don't fit cleanly inside one trade. Polymath spans embedded firmware, full-stack software, electronics, machining, welding, and CAD — so we can take a problem from blank page to deployed system without handing it off five times.
We take on contract engineering work for industrial customers who need more than a consultant and less than a 50-person firm. We do best when the problem is concrete, the goal is operational, and the customer wants the result deployed — not a slide deck.
Polymath runs lean by working with local contractors when the project warrants it. We're building a roster of people we can call — welders, machinists, programmers, electronics techs, CAD designers — who do good work and live close enough to show up.
Alongside contract work, Polymath develops in-house industrial products.
An industrial door safety interlock system for bifold and hydraulic doors. ESP32-based, tilt-monitored, with a multi-tenant SaaS portal for operators and installers.
crashaxis.com →Polymath Industrial LLC was founded on the idea that the boundaries between trades — programming, electronics, machining, welding — are an organizational accident, not a feature of the work itself. The problems that show up in real industry don't respect those lines, and the customers paying to solve them shouldn't have to either.
Polymath is based in Superior, Montana, in the Bitterroot range of Mineral County. The shop sits at 30 Mullan Road. Customers and contributors are within an hour of Missoula and a day's drive of most of the Northwest.
The company is led by David Grillot, a full-stack engineer with two decades of work across embedded systems, industrial software, and manufacturing operations.
