Spanish energy technology startup Linkener has raised €7.5 million in a round led by Klima, the energy transition fund of investment bank Alantra. Existing investor GoHub Ventures remains a shareholder. The company will spend the money on product development, proprietary AI models, and acquisitions.
It is the second AI-led energy software company Klima has backed. The fund also led Dexter Energy‘s €23 million Series C in July 2025. Dexter serves renewable asset owners and traders. Linkener sits at the other end of the chain, selling to businesses that buy and use energy.
From energy monitoring to actionable savings
Linkener’s Intelligent Energy Management System (SIGE) combines its own remote metering hardware, data analytics, and AI. Customers use it to track consumption, validate energy bills, analyse electricity contracts, and flag anomalies that point to savings.
According to the company, it serves more than 2,000 customers and manages 10,000 energy supply points. It says those points account for 1.7 TWh of annual consumption, which it compares to a city of roughly 400,000 people.
Linkener is part software house, part installer, and the investment case rests on the software side growing faster. The new AI models are meant to automate invoice processing, validate consumption data, spot irregularities, and generate recommendations from millions of daily data points.
“This funding round will allow us to accelerate the transformation of a highly fragmented sector, where energy management remains rooted in practices from 40 years ago. We want businesses to have reliable data and technology to understand how much they spend on energy, anticipate their costs and make better decisions,” said José Ignacio Ruiz, CEO of Linkener.
Klima backs consolidation in a fragmented market
Acquisitions are a stated part of the plan. Linkener intends to buy companies that add complementary products, technologies, and services, then fold them into one platform.
“Energy management for businesses and organisations remains a highly fragmented market with enormous potential for digitisation. Linkener combines proprietary technology, independent energy data and direct relationships with thousands of customers, creating a distinctive foundation on which to add further capabilities and solutions. Our investment aims to support the team in this next stage of growth, both organically and through acquisitions, with the goal of building a leading technology platform for energy management,” stated Iñigo Echaniz, partner at Klima.
GoHub Ventures first invested in 2019 and is staying in. “This funding round opens a new chapter that puts us at the heart of the sector, exceptionally well positioned to scale and consolidate the market. We are very excited to continue our support because we believe they truly lead the sector in their approach to AI and technology,” added Víctor Vercher, Partner at GoHub Ventures.
Competition and market outlook
European energy software has drawn steady funding. Dutch startup Tibo Energy raised €6 million in seed funding in June 2025 for AI-driven energy management at industrial sites. Finnish company Capalo AI raised €11 million in Series A funding in February 2026 to optimise battery storage and renewable assets. Nomos raised $20 million from Index Ventures to tackle European energy costs.
Most of these companies target different parts of the value chain than Linkener, but they share the same thesis: software can turn messy energy data into cheaper decisions.
Proof is the harder part. The International Energy Agency reports that energy service company projects delivered average savings of around 25% in 2024, with established markets such as Europe reporting 20%–30%. That is an industry benchmark, not a Linkener result, and the company’s own savings figures have not been independently audited.
An acquisition-led plan raises the stakes. Linkener will need to integrate new businesses, keep its data clean across them, and show customers measurable returns. The €7.5 million gives it room to start, and the first deal will show how it intends to use it.
