German SMEs are finding relief from soaring energy costs thanks to a recent approach from Einklang, a Cologne-based energy solutions provider. The company recently secured €2.2 million in funding to scale its battery-optimized electricity tariff, a system designed to slash power bills for mid-sized businesses by as much as 40%. This comes at a critical time, as European companies grapple with energy price volatility and the transition to renewable sources.
The funding round was led by Vireo Ventures, with participation from SI Ventures, Saxovent, Angel Invest, Heimatboost, and DnA Ventures. Einklang’s model focuses on integrating battery storage with smart software to optimize when companies store, apply, or trade electricity, ultimately reducing expenses and improving energy autonomy. The company was founded in 2025 by alumni from Voltfang and Impuls Energy, bringing significant experience in the energy sector to bear on this challenge.
“We’re solving a central problem of the energy transition,” explains Lucas Jonas, co-founder and CEO of Einklang. “While energy-intensive industries are granted relief through tailored regulations, mid-size companies continue to face high electricity prices. The issue isn’t renewable energy itself, but rather price volatility, high grid charges, consumption peaks, and a lack of flexibility. Our solution tackles exactly these problems.” The company’s approach is particularly relevant as renewable energy sources – solar and wind – develop into increasingly dominant in Europe, often imported from China, creating a need for better grid management and storage solutions.
Addressing a Gap in the Market
Einklang’s focus on SMEs is strategic. While larger industrial consumers often benefit from specific energy relief programs, smaller and medium-sized businesses are frequently left to navigate volatile markets on their own. The company provides a fully integrated solution, including intelligent control systems, battery storage, and flexible tariffs, without requiring upfront investment or ongoing operational effort from its clients. According to Einklang, businesses using the system can potentially lower electricity costs by up to 50%, achieve up to 50% energy autonomy, and cover up to 100% of their power needs with renewable energy.
The core of Einklang’s offering lies in coordinating electricity procurement, storage, and consumption. By automatically sourcing power when it’s inexpensive and renewable, the system helps reduce price volatility, lower grid fees, and improve planning certainty for businesses. The solution is already deployed at manufacturing and industrial sites, with new locations typically transitioning to the battery-optimized tariffs within three months.
A Broader Trend in Energy Tech Investment
Einklang’s funding is part of a larger surge in investment within Europe’s energy flexibility market. Across 2025 and 2026, several other companies focused on battery storage, AI-driven optimization, and decentralized energy systems have attracted significant funding. France-based enshift secured €18.5 million to scale integrated energy-transition solutions, while Barcelona-based WtEnergy raised €10 million for its industrial waste-to-energy projects.
The Netherlands is also seeing substantial activity in this space, with Utrecht-based iwell attracting €27 million for smart battery storage and Amsterdam-based Dexter Energy securing €23 million for AI-driven forecasting. Even in the UK, Bristol-based Anaphite received €1.6 million to develop advanced battery technology. Collectively, these rounds represent approximately €83 million in disclosed funding.
Vireo Ventures Sees Long-Term Potential
Vireo Ventures’ decision to lead Einklang’s funding round reflects a belief in the company’s vision and the strength of its team. “The decisive factor for our investment was the exceptionally strong team at Einklang, with its practical experience from previous ventures and industry expertise,” said Felix Krause, Partner at Vireo Ventures. “Einklang has a clear vision of becoming a decentralised full-service provider for flexible energy systems in the mid-sized business sector. The current regulatory framework creates significant potential for integrated solutions combining battery storage, PV, dynamic tariffs, and intelligent control.”
This investment signals a growing recognition of the need for flexible energy systems to support the transition to renewable energy sources and manage grid stability. Einklang plans to use the funding to further develop its technology platform and forge strategic partnerships to establish these systems as the new standard for German SMEs.
Looking ahead, Einklang will focus on expanding its customer base and refining its technology. The company’s success will likely depend on its ability to navigate evolving energy regulations and maintain its competitive edge in a rapidly growing market. The broader trend suggests continued innovation and investment in energy flexibility solutions across Europe.
