Company · About

Proof, not paperwork.

Demia builds the infrastructure that signs, governs, and verifies operational data at the source. We start with the commodity markets the global economy is built on: agriculture, energy, and critical minerals. From there we extend to the defense, industrial, and environmental supply chains that depend on them, where a claim is only as good as the evidence behind it.

We started from a simple observation: most compliance and audit failures aren't fraud, they're gaps: a handoff that wasn't logged, a record reconstructed after the fact instead of captured at the moment it happened. Demia closes that gap at the point of capture, so the record is trustworthy before anyone has to argue about it.

Leadership

The team running the company.

A U.S. Army combat veteran and DoD digital forensics and cybersecurity operations planner, with a background spanning NSA, USCYBERCOM, and DC3 forensics work. Led mobility and automotive data-verification programs at an early distributed-ledger technology foundation before founding Demia to bring that same rigor to compliance-critical data. Ten years into building this technology, it is now commercially mature enough to run at enterprise scale.

Track record

Building this for a decade. Ready to scale now.

Demia's team has spent the better part of ten years building and hardening the verification technology behind the Fabric, across mobility, automotive, defense, and environmental-data programs, long before Demia existed as a company. That history is why the platform arrives commercially mature: production hardened cryptographic verification, not a research prototype still finding its first customer.

10 years

building and hardening distributed verification technology across mobility, defense, and environmental-data programs.

6 patents

filed on the core verification and data-fabric technology now running in Demia's platform.

10,000+ datapoints/sec

verified in real time by the Fabric, from edge hardware that runs on as little as 15 to 65 watts.

DDIL-capable

operates disconnected, denied, intermittent, or limited environments, onsite and self-hostable, with no required external data egress.

Jaguar Land Rover

Historical work from the founding team's prior roles: EV battery material traceability across a multi-tier automotive supply chain. Case study available on request.

EU Horizon programs

Led work under CityxChange and DIG_IT, contributing to EBSI, GAIA-X, and Catena-X data-trust standards.

Chile, 2018 to 2022

Digital MRV pilots recognized by the World Bank and UNEP.

Commercially mature

A platform ready for enterprise deployment now, not a pilot still proving the concept.
