Company overview

Software-defined battlefield power that senses, prioritizes and routes power across mission-critical systems.

Amphora 24 (5 kWh, Pelican-case portable) and Amphora 400 (315 kWh) silent variable power for distributed operations, electronic warfare, and autonomous systems at the tactical edge.

Evidence boundary

Original analysis and independent corroboration remain under development. Commercial scale and durable technical advantage remain under review.

What makes it defensible

Silicon-carbide power electronics and high-voltage lithium packs sourced from EV/eVTOL supply chains, ruggedized for field use — the power layer every soldier-carried system plugs into.

Position in the stack: Bottleneck owner of battlefield power distribution: sits between raw energy inputs (generators, vehicles, solar) and every tactical load — EW, autonomous systems, comms. Hard to copy because it needs mil-spec ruggedization plus Army/DIU qualification (fielded with the 101st Airborne), not merely cell supply.

Who buys it

Named customers: U.S. Army units, Defense Innovation Unit (DIU)
