Linkener lands €7.5M from Alantra’s Klima to roll up Spain’s fragmented business energy software market

Spanish energy software startup Linkener has raised €7.5 million in a round led by Alantra’s Klima fund. Existing investor GoHub Ventures stayed in. The plan is not subtle: spend on product development, build proprietary AI models, and buy complementary companies.

That makes Linkener the second AI-led energy software company Klima has backed. The fund also led Dexter Energy’s €23 million Series C in July 2025, though Dexter serves a different part of the market. Linkener is aimed at businesses that buy and use energy, not the asset owners and traders further up the chain.

Its core product, the Intelligent Energy Management System, or SIGE, mixes remote metering hardware, data analytics and AI. Customers use it to track consumption, check energy bills, analyse electricity contracts and flag anomalies that may point to savings. Linkener says it serves more than 2,000 customers and manages 10,000 energy supply points, which it says represent 1.7 TWh of annual consumption. Those figures are self-reported and unaudited.

The software pitch is straightforward: automate the fiddly parts. The new models are meant to process invoices, validate consumption data, spot irregularities and turn millions of daily data points into recommendations. José Ignacio Ruiz, Linkener’s CEO, says the funding should help the company modernise a sector he described as still rooted in practices from 40 years ago.

Klima is buying into a roll-up story as much as a product story. It wants Linkener to acquire companies with complementary products, technologies and services, then fold them into one platform. Klima partner Iñigo Echaniz says the market is still highly fragmented and has room for digitisation, while GoHub’s Víctor Vercher says the company is well placed to scale and consolidate the sector.

The market is crowded with software-first energy companies chasing the same broad idea: messy energy data can be turned into cheaper decisions. But the useful bit will be whether Linkener can prove that promise with numbers customers trust, not just numbers the company publishes itself.
