Ulysses Ecosystem Engineering makes "cheap and cheerful" autonomous underwater vehicles that operate across both surface and subsea domains. Founded in 2023, the company is transforming ocean ecosystem restoration with fully autonomous, low-cost maritime robots.

The company's first focus is seagrass restoration—a vital habitat for biodiversity, fisheries, and coastal resilience—and a powerful carbon sink capturing 35 times more carbon than rainforests. Their robots speed up restoration by 100x compared to manual planting by volunteers and at a fraction of the cost of other robots, reducing restoration costs by 10x while making projects 100 times larger and faster.

Ulysses raised $2M led by Lowercarbon Capital.
