Panthalassa secured $140 million in Series B financing led by Peter Thiel to fund ocean‑powered AI computing infrastructure.
New investors include John Doerr, Marc Benioff’s TIME Ventures, Max Levchin’s SciFi Ventures, Hanwha Group and others.
Funding will complete a pilot manufacturing plant near Portland and accelerate deployment of Ocean‑3 floating AI nodes in 2026.
Ocean‑3 nodes generate wave power, run AI chips onboard and transmit inference results via satellite, avoiding land‑based data centers.
