  • Aptimiz

    Participated · Equity · Jul 2026

    Aptimiz develops a data-collection tool for agricultural operations that aims to optimize the working time of farm operators. The company is based in Angers and has positioned itself as a specialist in improving farm labor efficiency. Following a prior capital increase in 2023 that included Demeter and Asterion, Aptimiz raised €1.4M in the most recent round to support international expansion. Investors in the new round include Demeter (Vitirev Innovation), Asterion, Kinvest, Marco&Co and the réseau sarthois. The company intends to deploy the funds primarily to internationalize its product and scale its commercial presence abroad.

  • Companion.energy

    Participated · Seed · Jun 2026

    Companion.energy operates a platform that unifies energy contracts, live operational data, and distributed assets to continuously forecast demand, track market exposure, and automatically execute energy decisions. The company positions its software as a system of execution rather than a monitoring dashboard, directing assets to times of lower prices or profitable grid sales. Founded in 2022, the 19-person startup reports more than €1M in annual recurring revenue after tenfold growth since May 2024 and serves major customers including TotalEnergies, KPN, the Port of Antwerp–Bruges, Interparking, and Proximus Group. It now manages over 2 TWh of annual energy use and supports more than 200 MW of distributed solar, wind, batteries, and EV charging assets. Companion.energy plans to use its recent funding to enhance multi-asset, multi-market optimisation and to expand into Germany and Spain.

  • NELSON

    Led · Seed · May 2026

    Founded in 2022, Nelson provides a modular software stack for fleet electrification including electrification planning, charging infrastructure management, total cost of ownership calculation and charge piloting. The platform ingests trajectories, fuel and charging sessions to build simulations and digital twins that compare electrification trajectories and infrastructure policies. Nelson reports commercial traction with around fifty clients and says it pilots roughly 50,000 vehicles across thermal and electric fleets, and that its revenue tripled in 2025 (no absolute figures disclosed). The team is compact (reported between 11 and 50 employees) and was co-founded by Alfred Richard (CEO), Inès Multrier and Octave Locqueville (co-CTOs) and Julien Bou Abboud (COO). The company targets scaling commercially in France and Europe and aims to manage 100,000 electrified vehicles by 2030. Nelson emphasizes a vendor-neutral position: it does not sell vehicles or chargers but offers decision orchestration between manufacturers, lessors and charging providers.

  • Bubble Robotics

    Led · Seed · Apr 2026

    Founded in 2025 by former robotics engineers from NASA and ETH Zürich, Bubble Robotics is developing a fleet of resident autonomous robotic systems designed to operate continuously at sea for extended periods without human intervention. The company applies advances in robotics, edge AI, and satellite connectivity to enable persistent inspection, environmental monitoring, and maritime security. It plans to commercialize through a robotics-as-a-service model, allowing operators to reduce upfront capital expenditure and the high daily costs associated with vessel-based missions. Bubble Robotics argues its approach can dramatically lower inspection costs by removing dependence on vessels and crews, which the company says account for roughly 80–90% of offshore inspection costs. The startup draws inspiration from satellite constellations and aims to build a distributed network of autonomous systems to deliver high-frequency underwater data for more efficient ocean management. Financially, the company has just completed a $5M pre-seed round to fund technology development and initial deployments.

  • Spark Cleantech

    Participated · Series A · Dec 2025

    Founded in 2022 out of CentraleSupélec laboratories, Spark Cleantech is a Paris-based deep-tech company aiming to slash emissions from energy-intensive sectors such as glassmaking, metallurgy, polymers and batteries. Its core product is a plug-in module that sits between an industrial site’s existing gas network and high-temperature burners, using proprietary pulsed plasmolysis to strip carbon from the fuel stream before combustion. The process yields two saleable, fully decarbonised outputs—hydrogen for heat and a solid carbon nanomaterial—while cutting CO₂ emissions by as much as 85 percent and multiplying the economic value of the input gas four-fold. The pulsed plasmolysis technology, initially invented at Stanford University and refined at CentraleSupélec, is now being piloted with major industrial customers across Europe. With fresh capital, the company plans to complete and operate its first full-scale production module, qualify its inaugural commercial carbon grades, and hire roughly 20 employees in commercial, engineering and R&D roles. Spark Cleantech positions itself as both an emissions-reduction solution provider and a supplier of high-value carbon additives for polymer and battery markets.
