Precision Magnetics, Within Reach

Democratizing the Quantum Sensing Frontier

High-precision magnetic sensing used to require massive, cost-prohibitive systems. Praxion changes that. We develop room-temperature NV-diamond sensors that deliver picotesla-class accuracy on a single chip. Low-power, affordable, and US-manufactured, Praxion makes quantum-grade navigation and diagnostics accessible for mass-market drones, autonomous vehicles, and industrial platforms

High-precision magnetic navigation already works, it's how platforms hold their position when GPS is jammed or gone (GPS‑denied navigation). But it lives at the top of the market: big, power-hungry, expensive systems bolted into vehicles that cost orders of magnitude more than the sensor. Everything below that tier has been locked out, not by physics, but by size, power, and price.

The Problem

Praxion builds magnetometry around nitrogen-vacancy centers in diamond, a room-temperature quantum sensor that resists drift and, unlike the alternatives, shrinks to chip scale at chip-level power.

Praxion's sensor pairs best-in-class NV diamond, patent-protected and available exclusively to Praxion, with photonics integration built for a real foundry process and the manufacturing operations to test and build it at scale. Proven material, integrated photonics, and a US fab trusted across defense and telecom.

A Different Foundation

NV-diamond sensing is past the physics. What's left is engineering. Diamond fabrication, photonics, and edge compute have matured in parallel, and demand for GPS-denied navigation and photonic integrated circuit (PIC) instrumentation has never been higher. The window to build the company that productizes it is open now.
