# Panthalassa

> Panthalassa is a Portland, Oregon public-benefit corporation building autonomous, mass-produced floating nodes that harvest wave energy in the open ocean and use it on the spot to run AI compute, beaming inference results back to land by satellite. Founded in 2016, the company raised a $140M Series B in May 2026 led by Peter Thiel to finish its pilot manufacturing facility and deploy its Ocean-3 node series.

- **Founded:** 2016
- **Headquarters:** Portland, Oregon, United States
- **Founders:** Garth Sheldon-Coulson (Co-Founder & CEO), Brian Moffat (Co-Founder)
- **Team size:** 75 employees
- **Products:** Ocean nodes, Ocean-3 series, At-sea AI compute
- **Notable:** Raised $140M Series B led by Peter Thiel in May 2026, Deployed Ocean-1 prototype (2021) and Ocean-2 pilot (2024) in the Pacific, Built at-sea computing infrastructure over nearly a decade of R&D

## Products & services

- **Ocean nodes** — Autonomous, floating energy systems mass-produced from plate steel in coastal factories. They generate clean electricity around the clock from wave motion in energy-dense ocean regions.
- **Ocean-3 series** — Pilot node series planned for deployment in the northern Pacific in 2026 to demonstrate AI inference at sea and refine manufacturing ahead of commercial deployments in 2027.
- **At-sea AI compute** — Rather than transmitting energy back to land, nodes run AI inference chips onboard - cooled naturally by the ocean - and send inference tokens to land via low-Earth-orbit satellite.

## Achievements

- Raised $140M Series B led by Peter Thiel in May 2026
- Deployed Ocean-1 prototype (2021) and Ocean-2 pilot (2024) in the Pacific
- Built at-sea computing infrastructure over nearly a decade of R&D
- Assembled a team from SpaceX, NASA, Apple, Boeing and Tesla
- Building a pilot manufacturing facility near Portland, Oregon

## Latest updates

- **2026-05** — Closed $140M Series B led by Peter Thiel to finish pilot manufacturing facility and accelerate Ocean-3 node deployment.
- **2026** — Planning Ocean-3 pilot node deployment in the northern Pacific to demonstrate AI inference at sea.
- **2024** — Deployed Ocean-2 pilot in the Pacific; prototype spotted as an 'unidentified floating object' during testing in Puget Sound.
