ALVA Energie secures €5.2 million in successful first round of financing to scale up decentralized energy concepts

Start-up for tenant electricity founded in 2024 continues to grow dynamically


  • Renowned investors from the energy, real estate, banking, and venture capital sectors
  • Additional capital flows into vertically integrated business model with holistic energy solutions: planning, implementation, and operation of solar projects

Berlin / Schönefeld, 16.07.2025 – The Berlin-based energy start-up ALVA Energie has successfully completed a scheduled financing round of around 5.2 million euros. Investors include Württembergische Energie GmbH, Brandenburg Kapital GmbH, a subsidiary of the Investment Bank of the State of Brandenburg (ILB), and the European Social Innovation and Impact Fund (ESIIF). In addition, several well-known business angels from the better ventures network with proven expertise in the energy and real estate sectors also participated.

ALVA offers residential and commercial property owners and tenants decentralized energy solutions with a focus on tenant electricity from a single source, from design and installation to ongoing operation. The additional capital will be invested specifically in scaling the vertically integrated 360° business model. To date, 50 projects have already been successfully implemented. The goal is to double this number of projects by the end of the year, thereby saving nearly 6,000 tons of CO2 emissions.

Cecil von Croy, co-founder and CEO of ALVA Energie, comments: "Since our founding around 18 months ago, we have successfully grown from a standing start to a profitable business with revenues in the millions, thereby demonstrating on our own that there is enormous potential in holistic, decentralized energy solutions. This has now put us in a position to work with exactly the right partners for the upcoming scaling of our business model, partners who, thanks to their many years of specialized experience, will deliver the greatest added value beyond their capital. This applies in particular to the three main pillars of our business model—energy, real estate, and financing."

Binh Vu, Investment Manager at Brandenburg Kapital: "Decentralized solar energy is an important lever for the energy transition in Germany. We see great potential in the tenant electricity segment in particular for supplying cities and ultimately individual tenants with energy in a cost-effective and sustainable manner. The ALVA team has quickly established a solid foundation for implementing scalable solutions for the real estate industry. We are impressed by the team's technical expertise and implementation skills. We look forward to supporting this growth and contributing to the decentralized energy future in Germany."

Tina Dreimann, co-founder and managing director of better ventures: "The energy transition will be decided in the existing building stock. ALVA shows how it is possible to provide millions of tenants with access to affordable, green electricity—with a clearly scalable model and impressive implementation power. These are exactly the kind of founding teams we need to bring impact and economic success together. That's why we're proud to accompany ALVA on its journey."
