Ulysses
Ulysses is a San Francisco ocean-robotics company building low-cost, modular autonomous underwater vehicles that replace multimillion-dollar ships and human divers. Founded in 2023, it started by using robots to replant declining seagrass meadows 100x faster than volunteer divers, then extended the same modular platform to offshore wind surveys, subsea infrastructure inspection, and maritime security. Its flagship Mako AUV dives 5,000 feet for up to 72 hours and starts at roughly $50,000 - about 50x cheaper than legacy systems - and the company raised a $38M Series A led by Andreessen Horowitz in April 2026.
Ocean Aero Inc
Ocean Aero builds the Triton, the world's only autonomous vehicle that both sails on the surface and dives beneath it, powered entirely by sun and wind. Founded by U.S. Navy veterans in 2012 and now headquartered in Gulfport, Mississippi, the company makes long-endurance, crewless ocean robots used by the U.S. Navy and allied partners for surveillance, mine countermeasures, and ocean research, as well as by energy and science customers for seabed mapping and environmental monitoring.
