Amphitrite is our startup of the day, winner of the ranking We Innovate 500 2025, classified in 127th position.
Amphitrite develops an artificial intelligence technology that merges satellite data to produce high -resolution ocean forecasts, with immediate applications in optimizing maritime transport and the fight against plastic pollution.
Founded at the end of 2021 by Alexandre Stegner,, BRIAC seen him And Evangelos Moschosthree researchers from the CNRS and the Polytechnic School, Amphitrite was born from the observation that oceanographic data exist, but are little exploited by industrial actors for lack of reliable tools to interpret them.
The heart of their technology is based on models ofIA specialized in the forecast of surface currentsbuilt from heterogeneous satellite data (surface temperature, chlorophyll, altimetry, swot data). Their module Hires-Currents provides high resolution forecasts (3.6 km, every hour) up to ten days in advance. These data allowOptimizing sea routes in real timetaking into account the veins of currents to reduce fuel consumption, improve punctuality and lower CO₂ emissions.
The use cases are concrete. In the Mediterranean, a simple trajectory adjustment allowed a Ro-Ro ship to gain an hour of navigation and reduce its fuel consumption by 4 %. On the Northern Atlantic, a trigger avoided an area of counter-counders, saving more than 3,600 euros in fuel and reducing its co₂ emissions from 16 to 19 tonnes in a single journey.
Beyond navigation, Amphitrite also develops solutions for Detect floating plastics accumulation areasfacilitating their recovery. The company thus puts its skills in AI and oceanography at the service of logistics performance and the preservation of ecosystems.
Protected by a CNRS patent, Amphitrite collaborates with industrial and public partners such as CLS,, The CNES,, Ocean Data Lab Or Louis Dreyfus Armateur. It was incubated within the X-UP and X-Tech programs of the Polytechnic School. Amphitrite raised 1.2 million euros in 2024.
