French wave energy startup Seaturns has completed a new fundraising round through the Keenest platform, securing investment from over 1,500 individual backers along with renewed support from existing shareholders, including Team For The Planet and Sébastien Duez. The round also marks the entry of Deputy CEO Lawrence Sigaud into the company’s capital.
“We warmly thank the 1,543 investors who have placed their trust in us. This support is crucial for deploying our full-scale demonstrator and accelerating our industrial development,” said Vincent Tournerie, founder and president of Seaturns.
The company’s patented technology is designed to generate clean and decentralized electricity from ocean waves, with a focus on resilient design, low-cost manufacturing, and simplified deployment. Following the successful testing of a ¼-scale prototype at Ifremer in Brest over 18 months, Seaturns is now preparing to install its full-scale demonstrator at the Sem-Rev offshore test site in summer 2025.
“I invested in Seaturns because we are developing a high-potential emerging technology for Europe’s energy mix,” said Deputy CEO Lawrence Sigaud. “We are providing a concrete solution to decarbonization challenges and actively preparing for industrial scale-up.”
Proceeds from the fundraising will go toward finalizing R&D efforts, launching industrial production, and expanding international commercialization. Since its founding in 2015, the Bordeaux-based company has received support from public institutions including Bpifrance, Horizon Europe, the French government, Nouvelle-Aquitaine Region, and Ifremer.
