SMEs cut electricity costs by 30–40% with Einklang as it raises €2.2 million to scale its battery-optimised tariff

The Cologne-based company Einklang, specialised in integrated energy solutions for Germany’s mid-sized businesses, has secured €2.2 million to scale its battery-optimised electricity tariff solution for SMEs – reportedly reducing electricity costs by 30 to 40%.

The funding round was led by Vireo Ventures. Other investors include SI Ventures, Saxovent, Angel Invest, Heimatboost, and DnA Ventures.

“We’re solving a central problem of the energy transition,” says 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.”

In addition to Einklang’s €2.2 million round, several comparable energy and battery-focused funding deals were reported by EU-Startups across 2025 and 2026.

France-based enshift secured €18.5 million to scale integrated energy-transition solutions for real estate and infrastructure assets. In Spain, Barcelona-based WtEnergy raised €10 million to expand its industrial waste-to-energy and biomass gasification projects across Europe.

The Netherlands has seen a good amount of activity in this space. Utrecht-based iwell attracted €27 million to deploy its smart battery storage and energy management systems for commercial and industrial users Amsterdam-based companies Dexter Energy raised €23 million to scale AI-driven forecasting and optimisation software for renewables and battery trading, and Chapter raised €3 million to build an AI-powered operating system for sustainable energy installers and manufacturers.

In the UK, Bristol-based Anaphite secured €1.6 million to develop dry-coating technology for lithium iron phosphate batteries.

Collectively, these rounds represent approximately €83 million in disclosed funding, illustrating continued capital deployment into European energy infrastructure, battery systems, and optimisation software.

Within this broader context, Einklang’s €2.2 million raise represents an early-stage but targeted play in the commercial and industrial energy segment, specifically addressing German SMEs. While larger rounds such as iwell’s and enshift’s reflect scaling ambitions in storage and integrated transition models, Einklang focuses on coordinating procurement, storage, and consumption through battery-optimised tariffs.

The concentration of funding in battery storage, AI-driven optimisation, and decentralised energy systems suggests sustained investor interest in flexibility solutions that reduce peak loads and price volatility.

“Only when consumption, storage, and procurement are intelligently coordinated can electricity become both affordable and predictable,” adds Lucas. “Our goal is to ensure that companies automatically use power when the sun shines or the wind blows – smartly and without any operational complexity.”

Founded in 2025, Einklang is an Energy-as-a-Service provider serving Germany’s SMEs. The founders bring years of experience from building and scaling companies such as Voltfang (Aachen) and Impuls Energy (Cologne).  

The company supplies commercial and industrial customers with fully integrated electricity solutions combining intelligent control systems, battery storage, and flexible tariffs – with no need for customer investment or operational effort.

Depending on their baseline, companies can allegedly lower their electricity costs by up to 50%, achieve up to 50% energy autonomy, and cover up to 100% of their power needs with renewable energy. Einklang positions itself as a long-term energy partner, supporting a cost-effective and future-ready energy transition for mid-sized businesses.

By integrating electricity procurement, storage, and consumption, Einklang enables companies to automatically source power when it’s inexpensive and renewable. This helps to reduce price volatility and peak loads, lower grid fees, and improve planning certainty.

The solution is already in use at manufacturing and industrial customer sites. New sites can generally be transitioned to battery-optimised tariffs within three months.

“The decisive factor for our investment was the exceptionally strong team at Einklang, with its practical experience from previous ventures and industry expertise. 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,” says Felix Krause, Partner at Vireo Ventures.

With this funding round, Einklang is sending a strong signal for a sustainable energy transition in the industrial Mittelstand. The company will now focus on further developing its technology platform and building strategic partnerships to establish flexible energy systems as the new standard for mid-sized businesses.
