Mission
Our mission

The world needs more compute — and it needs it cleaner, faster, and closer to people. We build it beneath the sea.

Why subsea

The ocean is the better place for compute.

Near-limitless cooling, direct access to subsea power and fiber, and proximity to the coastal regions where most of the world lives. The sea solves the problems land can't.

The units

Engineered to run for decades.

Modular, standardized, and built from durable, responsibly sourced materials. Deployed in 12 weeks, designed for 25+ years, and cooled for free by the sea — running at a PUE of 1.01.

Deployed & proven

From engineering conviction to reality.

Our units integrate with existing subsea infrastructure and co-locate with offshore renewables — deployed across the USA, Asia, and Norway, and tested with real clients.

The team

A deep-technology company.

We're engineers first. Using a first-principles approach, we're modernizing the subsea economy — in partnership with clients, installers, and the offshore industry.
