German energy startup ALVA Energie has successfully concluded its first funding round of over €5 million to scale decentralised energy solutions and its vertically integrated 360° business model.
Investors include Triodos Bank, Württembergische Energie GmbH, Brandenburg Kapital GmbH, a subsidiary of Investitionsbank des Landes Brandenburg (ILB), better ventures, and the European Social Innovation and Impact Fund (ESIIF). Other private equity investors include Dr Christian Schmalenbach (Managing Partner of Hystake), Jan Rabe and Max Both (Founders of Rabot Energy), Marko Vogt (Founder of Solarblick), Olaf Schlüter (Managing Partner of Cresco Projektentwicklung) and Tobias Mehrer (Managing Director of 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 (ALVA) innovates in the field of landlord-to-tenant-electricity
The company’s main goal is to attain global sustainability goals, make significant reductions in C02 emissions, and ultimately counteract climate change, by making sustainable and holistic energy solutions and landlord-to-tenant-electricity
ALVA provides decentralised energy solutions to residential and commercial property owners as well as tenants. They focus on in-house landlord-to-tenant electricity and cover planning, installation and operations.
To date, over 50 such projects have already been successfully completed by ALVA. The goal is to double the number of projects by the end of the year, reportedly saving almost 6,000 tons of CO2 emissions.
ALVA’s business model pursues a vertically integrated 360° concept, supporting owners and tenants of residential and commercial properties throughout Germany – from planning, financing and installation all the way to reliable management during the ongoing operation of solar power projects.
The company offers customers the choice of flexible roof leases, system leases or certain supply chain 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
“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 works together with private owners, larger real estate companies and investment funds. Under the KARLSSONN brand, the company also provides residential tenants with green electricity produced directly on site.
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.“
