Private investors also joined in, including Dr. Christian Schmalenbach (Hystake), Jan Rabe and Max Both (Rabot Energy), Marko Vogt (Solarblick), Olaf Schlüter (Cresco Projektentwicklung), and Tobias Mehrer (Ranger Marketing).

Cecil von Croy, Co-founder and CEO of ALVA Energie said: “Since our foundation around 18 months ago, we have already successfully and profitably grown to be a multi-million euro revenue company, thereby demonstrating what enormous potential holistic and decentralised energy solutions hold.

“This has now put us in a position to work more closely with precisely those investors, who – thanks to their many years of unique industry experience – offer us valuable insights on top of their additional funding to continuously scale our business model in the future. This particularly applies to the three main pillars of our business model: energy, real estate and financing.”

Founded in 2024, ALVA Energie is transforming the landlord-to-tenant electricity space. Started by Cecil von Croy, Alexis Cramm, Marc Schuhbauer, Franziskus Cramm and Marian Hallal, ALVA aims to cut CO2 emissions and promote sustainable energy access.

ALVA delivers decentralized solar power solutions for residential and commercial buildings, managing everything from planning to installation and operation. They've completed 50+ projects so far and aim to double that number by year-end, potentially saving 6,000 tons of CO₂.

Their 360° business model supports clients across Germany with flexible options like roof leases, system leases, or operator models.

Binh Vu, Investment Manager at Brandenburg Kapital added: “Decentralised solar energy is a consequential vector for the energy transition in Germany. We see great potential for landlord-to-tenant-electricity to supply cities and ultimately also tenants with sustainable and cost-effective energy. The team at ALVA have quickly established an extensive foundation for implementing scalable solutions for the real estate industry.

“We are impressed by both the technical expertise as well as the team’s swift and professional implementation of sustainable energy solutions. We look forward to supporting the respective growth of this company and this sector, thereby making a contribution to the future of sustainable decentralized energy in Germany.”

ALVA partners with private property owners, real estate companies, and investment funds. Through its KARLSSONN brand, the company also supplies residential tenants with clean, locally produced green electricity.

Tina Dreimann, Co-founder and Managing Director of better ventures: “The energy transition will be decided in existing buildings. ALVA demonstrates how it is possible to make affordable, green electricity attainable for millions of tenants across Germany – with a highly scalable business model and impressive implementation. These are exactly the kind of entrepreneurial teams we need to make a marked impact and facilitate economic success. That’s why we are proud to support ALVA on its journey.“
