Spanish start-up Linkener has raised €7.5m to build AI models into its energy management platform and to buy smaller rivals in a fragmented Spanish market.
Linkener, a Spanish firm that helps businesses track and cut their energy use, has raised €7.5m to grow its energy management platform. Klima Energy Transition Fund led the round, which the firm announced on 19 October. Klima is the energy transition fund of the investment bank Alantra.
GoHub Ventures, which first backed Linkener in 2019, is staying on as a shareholder seven years after that first cheque. The firm hasn’t named any other investors or disclosed a valuation.
What the money is for
Linkener plans to spend the money on two things. First, it will build out its energy management platform, including its own AI models. Second, it wants to grow by buying firms, products and skills that fit with its own, as well as by winning new clients. It hasn’t said how much of the €7.5m will go to each.
“This funding round will allow us to accelerate the transformation of a highly fragmented sector,” said José Ignacio Ruiz, chief executive of Linkener. His backers see the same gap in the market.
Iñigo Echaniz, a partner at Klima, called energy management for businesses and organisations “a highly fragmented market”. So Linkener’s plan is to pull that market together, using the new money to buy smaller providers.
Meters, bills and contracts
The firm sells an energy management system, which it calls SIGE. It relies on Linkener’s own remote meters to log how much power a site uses and when.
The software then uses that data to digitise and check energy bills. It also reviews supply contracts and sends alerts and tips when it spots a chance to save. In short, the platform pairs physical meters with advice that a finance or facilities team can act on.
Next, Linkener plans to use AI to automate bill processing. It also wants its software to flag odd spikes in use and find savings, without a person checking every account. “We want businesses to have reliable data and technology to understand how much they spend on energy,” Ruiz said.
Customers and scale
Linkener says it has more than 2,000 customers and runs 10,000 energy supply points. Together, those sites use 1.7 TWh of energy a year, according to the firm. It compares that with the yearly use of a city of about 400,000 people. It has also fitted more than 400 solar and battery systems across Spain.
The firm reports these figures itself, and no one has audited them. Likewise, its claim that tracking and control can save around 20 per cent of energy use in the services sector is its own estimate.
Víctor Vercher, a partner at GoHub Ventures, praised the team’s technical approach. He said “we believe they truly lead the sector in their approach to AI and technology”.
A consolidation play in business energy
The buying plan is the most distinctive part of the raise. Linkener wants to roll up smaller rivals and move their clients onto one energy management platform. Its own meters and billing software would sit at the centre of that.
Klima has backed energy software firms before Linkener. For instance, the fund led a Series C round in Dutch forecasting firm Dexter Energy in July 2025. Its parent has also grown its energy transition investments this year.
Meanwhile, other European energy software start-ups have raised money of late. Tibo Energy closed a €6m seed round in June 2025, while Capalo AI raised an €11m Series A in February 2026.
Linkener’s round is smaller than some of those, but it comes with a clear brief. The money pays for new AI tools and for deals to buy rivals. The firm’s first acquisitions will show how fast it can turn that plan into scale.
