Swedish AI company Cetasol has raised €2.3 million ($2.68 million) in seed funding to accelerate the rollout of its bunker fuel optimisation platform.

The round was co-led by BackingMinds and Shift4Good, with continued backing from existing investor Sarsia, Cetasol said in a statement on its website on Wednesday.

The firm’s flagship solution, iHelm, leverages real-time and historical vessel data to deliver AI-driven decision support, enabling operators to cut bunker consumption by 10-25%.

It combines vessel operating data with AI modelling to create a digital twin of the ship.

The system then recommends the most efficient power, speed and routing settings, helping crews reduce bunker consumption and costs, while also supporting predictive maintenance.
