Philadelphia, PA — Maritime Defense Hackathon March 2026

Hessian Industries

GPS does not work underwater, so every UUV, seabed platform, and sensor has to build navigation and C2 from first principles… often a six-figure transponder, or an INS that runs more than a hundred thousand dollars and drifts within an hour. When nav is priced like that, the math does not close for attritability. It's strangling the maritime ecosystem.

Hessian is the shared layer meant to make the math close: a deployable acoustic mesh of seabed nodes that can deliver sub-meter PNT, coordinate missions, all at a sub four-digit client cost.

This concept won us the US Maritime Hackathon, received a letter of intent to buy our IP, and was submitted as an application for a government contract.

Skills

Acoustic PNT, mesh networking, hydrophones, undersea C2, software-defined decoders, triangulation, rapid prototyping, marine hardware, machining, defence technology, on-prem software, acoustic engineering… and a bit of sneaking into places to test the tech.
