Ghent, Belgium, 8 June 2026 - Companion.energy, the softwareplatform helping large industrial and commercial enterprises manage energy inreal time, today announced the close of a €7.8 million seed round led byRealyze Ventures (Germany) and Pi Labs (United Kingdom), with participationfrom Asterion Ventures (France) and existing investors.

Over the last year, the company grew its customer base and revenuetenfold, surpassing €1 million in annual recurring revenue. The company nowserves more than 30 enterprise customers across Belgium, the Netherlands andSwitzerland, including TotalEnergies, KPN, Port of Antwerp-Bruges, Interparkingand Proximus Group. Among its customers are manufacturers, logistics operators,telecom operators, EV charging operators, energy companies and other largeenergy consumers.

The company manages more than 2 TWh of annual energy consumption andproduction across customer portfolios, representing approximately €500 millionin annual energy spend and energy revenues. Its platform already supports morethan 200 MW of distributed energy assets across solar PV, wind, batteries,e-boilers and EV charging infrastructure.

Through the platform, clients benefit from autonomous decision making onmaximising energy assets in real time, reducing energy costs by 10–30%.

Thomas Vyncke, co-founder, Companion.energy, said: “European energy marketsare undergoing a structural shift. As penetration of renewables increases andindustrial demand becomes more electrified, electricity markets are becomingsignificantly more volatile and operationally complex. Energy prices that oncemoved seasonally now fluctuate in real time. At the same time, enterprises aredeploying growing fleets of batteries, solar installations, EV charginginfrastructure and electrified industrial systems. Most companies still managethis environment through fragmented tooling, spreadsheets and staticprocurement processes but they need a system that runs and optimises energyoperations continuously.”

Jonas Verstraeten, co-founder, Companion.energy, said: “We started Companionbecause we believed the energy transition would force every large industrialenterprise to manage energy actively, and that they would not be able to dothat with spreadsheets and quarterly check-ins. The work of the next decade is togive those teams software that can keep up. This round lets us bring thatsoftware to many more enterprises, and help them turn their energy from acompetitiveness risk into a competitive advantage.” says.

Companion.energy connects energy contracts, operational systems anddistributed assets into a single optimisation platform that continuouslyforecasts demand, models market exposure and automates energy decisions in realtime. The platform helps enterprises optimise procurement decisions, steerassets dynamically and improve the economics of electrification at scale

The new funding will support two priorities: deepening the platform’smulti-asset, multi-market optimisation capabilities, and expanding commerciallyacross Europe, starting with Germany and Spain.

Marnix Roes, Investment Manager at Realyze Ventures, said: “We were deeply impressedby the robustness of Companion.energy’s software and its ability to managehighly complex enterprise energy environments across multiple sites and markets.Germany alone represents a massive opportunity as industrial and commercialenterprises increasingly look for ways to optimise flexibility, electrificationand energy exposure operationally rather than manually.”

Dhruv Gupta, Principal at Pi Labs, said: “Enterprise energy management ismoving from static procurement and reporting toward 24x7 real-time optimisation.Large enterprises spending tens of millions annually on energy still relyheavily on spreadsheets, dashboards and manual workflows. Companion has built adeeply technical AI platform that fundamentally changes software from arecommendation engine to a system of execution. This is what makes thiscategory so important.”
