Companion.energy closes a €7.8M seed round to scale its real-time energy optimisation platform for large industrial and commercial enterprises
Companion.energy has closed a €7.8M seed round led by Realyze Ventures and Pi Labs to scale its real-time energy optimisation platform for large industrial and commercial enterprises.
Founded in 2022, the company grew its customer base and revenue tenfold in the past year, surpassing €1M in annual recurring revenue, with clients including TotalEnergies, KPN, and the Port of Antwerp-Bruges.
The round brings total funding to around €10M and funds expansion into Germany and Spain.
A 19-person Belgian startup now manages over 2 TWh of annual energy use, worth around €500M in combined energy spending and revenue, for clients including TotalEnergies, KPN, the Port of Antwerp-Bruges, Interparking, and Proximus Group. That scale, for a company less than three years old, is the reason investors are paying attention.
Companion.energy, founded in 2022 by Thomas Vyncke and Jonas Verstraeten, has closed a €7.8M seed round led by Realyze Ventures and Pi Labs, with participation from Asterion Ventures and existing investors.
“Energy prices that once moved seasonally now fluctuate in real time. Enterprises are deploying growing fleets of batteries, solar installations, EV charging infrastructure and electrified industrial systems. Most companies still manage this environment through fragmented tooling, spreadsheets and static procurement processes — but they need a system that runs and optimises energy operations continuously,” Vyncke says.
Moving from dashboards to real decision-making
Companion.energy brings together energy contracts, live operational data, and distributed assets into one optimisation platform. It constantly forecasts demand, tracks market exposure, and automatically executes energy decisions, directing assets to times when electricity is cheapest or when selling back to the grid is most profitable.
The platform competes in a market that includes established players such as Siemens’ energy management software and Schneider Electric’s EcoStruxure, as well as newer entrants like encentive, which raised €6.3M in September 2025 to cut industrial energy costs with AI.
Where incumbents tend to offer monitoring dashboards and periodic reporting, Companion positions itself as a system of execution.
“Companion has built a deeply technical AI platform that fundamentally changes software from a recommendation engine to a system of execution,” says Dhruv Gupta, principal at Pi Labs.
The company says it now manages over 2 TWh of annual energy use for its customers, amounting to around €500M in combined energy spending and revenue. It also supports more than 200 MW of distributed assets across solar, wind, batteries, and EV charging infrastructure.
Between May 2024 and the close of this round, Companion.energy grew its customer base and revenue tenfold, reaching more than €1M in annual recurring revenue. That growth rate is striking, though the starting point was small.
Why Germany is next
The new funding will support two priorities: improving the platform’s ability to optimise across multiple assets and markets simultaneously, and expanding into Germany and Spain.
“Germany alone represents a massive opportunity as industrial and commercial enterprises increasingly look for ways to optimise flexibility, electrification and energy exposure operationally rather than manually,” says Marnix Roes, investment manager at Realyze Ventures.
This round brings Companion.energy’s total disclosed funding to around €10M, including the €2.1M raised in May 2024. The company currently employs 19 people.
As industrial energy costs become a boardroom issue across Europe and as volatility driven by the renewables transition shows no sign of easing, the real question is whether real-time automation can become standard infrastructure for large enterprises, or whether the complexity of integrating dozens of assets and markets proves too great for any single platform to crack.
