Solfy, Spain’s first digital marketplace for energy solutions, has successfully closed its third funding round, raising €4 million in a mix of debt and equity. This milestone follows its previous raises of €415,000 in 2022 and €1 million in 2023, providing the company with a reinforced financial structure to consolidate its leadership in the clean energy sector.
The round was backed by two prominent investors in the Spanish market: Bonsai Partners, one of the country’s most relevant early-stage venture capital funds with a successful track record in companies such as Idealista, InfoJobs, Glovo, Wallapop, and Exoticca; and Ona Capital, the family office of the Benito and Bonpreu families, with a strong track record in long-term strategic investments.
This capital injection will allow Solfy to accelerate its expansion plan and continue scaling its fully digital end-to-end model, which provides households, residential communities, and businesses across Spain with access to self-consumption energy solutions.
At the same time, Solfy has strengthened its local presence and operational capabilities with two key moves in 2025: the acquisition of Ecolium, an installation company based in L’Escala (Girona) with more than 800 clients, and the incorporation of DC Solutions, a firm specialized in engineering, execution, and maintenance of photovoltaic projects in southwestern Spain. These integrations add local reach, technical expertise, and proximity, reinforcing the company’s strategic positioning.
“With this funding round and our recent acquisitions, Solfy is consolidating its role as a key player in Spain’s energy transition,” said Sergi Sans, CEO of Solfy. “Our goal is to lead the shift towards a decentralized, accessible, and user-centric energy model, and now we have the resources to do so at a larger scale.”
Founded in 2022, Solfy closed 2024 with more than €7 million in revenue, over 1,000 installations completed, and a partner network spanning all Spanish provinces. With the integration of Ecolium and DC Solutions, the company expects to exceed €15 million in revenue in 2025, further consolidating its national market leadership.
The new funding will also support the continued development of Solfy’s energy management mobile app, which will provide users with real-time consumption monitoring, subsidy management, and energy savings optimization. This project has received support from CDTI due to its innovative nature and impact on the sector.
Solfy has positioned its platform as a benchmark in the energy sector thanks to its 100% digital, end-to-end model, covering everything from initial consulting and financing to installation, public grant management, and after-sales maintenance.
Its catalog includes solar panels, aerothermal systems (introduced in 2024), batteries, and EV chargers, offering turnkey solutions tailored to households, communities, and businesses.
In addition, Solfy is advancing towards becoming a full-fledged energy manager: the company will help customers select the operator and electricity tariff that best suits their needs, particularly after installing equipment that transforms their consumption and energy generation patterns.
Solfy is a technology company specialized in renewable energy and energy efficiency solutions. Founded in 2022 in Barcelona, its mission is to democratize access to clean energy through technology, transparency, and an integrated service model.
