Ulysses Ecosystem Engineering builds autonomous underwater vehicles, robotics and AI systems for ocean work, operating publicly as Ulysses / The Ocean Company. Its first vehicle, Mako, is a modular AUV rated to 5,000 ft with 72 hours of endurance and a 200 lb payload, paired with Kraken, an autonomous launch, recovery and recharge system that lets missions run fully remotely. The company began with seagrass restoration — using robotic drills to map seafloor and plant seeds at roughly a tenth of manual cost — with partners including The Nature Conservancy, the University of Western Australia, the Great Barrier Reef Foundation and the Florida Department of Environmental Protection. It raised a $2M pre-seed led by Lowercarbon Capital in 2024 and a $38M Series A led by Andreessen Horowitz in April 2026 to scale production for offshore energy and defense customers.
