Munich, 20 November 2025 — Delta Charge, a Swedish-German company that is pioneering charging and battery storage solutions for electric trucks, has raised $4.3m equity in an oversubscribed funding round led by Vireo Ventures and Rethink Ventures. The round includes executives from Audi and Allianz, German family offices and founders of Munich’s climate tech ecosystem. The funds will accelerate the growth of Delta Charge’s pan-European network of truck-charging depots and battery-enabled industrial hubs.

Founded in 2024 in Munich, Delta Charge combines battery energy storage systems (BESS) and charging hardware, energy management, and fixed-price charging services to enable European logistics and industry to unlock the economic advantages of large-scale energy operations. Backed by Delta Capacity, one of Scandinavia’s leading battery storage developers and investors, Delta Charge aims to deploy more than €300 million in infrastructure and deliver 1.8 TWh annually of clean energy by 2030.

“This financing marks a defining moment for Delta Charge as we scale our platform and continue to execute our vision,” said Filip Hes, CEO of Delta Charge. “We are seizing a once-in-a-decade opportunity to serve historic load growth and shape a new infrastructure asset class at the heart of Europe’s energy transition. With Rethink’s ambition to redefine transportation and Vireo’s strong commitment to European electrification, as well as Delta Capacity’s experience executing large scale battery projects, we are uniquely positioned to accelerate deployment across our pipeline.”

The announcement comes at a time when heavy-duty electrification is driving unprecedented load growth that could soon rival or even exceed the electricity consumption of Europe’s data centers. As transport could account for almost 50% of the continent’s CO2 emissions by 2030, logistics and freight operations present one of the largest untapped opportunities to substantially cut emissions while reducing per-kilometre costs.

“Operating electric truck fleets at the lowest possible total cost of ownership will rely on smart depot charging solutions that combine battery storage, charging infrastructure, and seamless software integration,” added Jens Philipp Klein, General Partner at Rethink Ventures. “The team at Delta Charge brings deep expertise across energy infrastructure execution, advanced battery software, and a track record of raising hundreds of millions towards rapidly scaling and executing infrastructure pipelines.”

With grid capacity tightening and permitting slowing, depot-based charging and battery storage are projected to attract more than €7 billion in investment by 2030. Positioned at the intersection of logistics and energy flexibility, Delta Charge aims to anchor the infrastructure powering Europe’s zero-carbon freight future.

Pionix raises over €8 million to scale EV charging enterprise products on the open-source EVerest stack, hosted by Linux Foundation Energy (LF Energy), which allows the industry to build on a shared software foundation.

The open-source approach accelerates innovation while dramatically improving reliability, interoperability and long-term maintainability across the global EV charging ecosystem, which currently sees failed charging session rates of up to 25%.

The EVerest stack is considered a highly impactful open-source initiative within the cleantech space, with an estimated ecosystem value of more than $500 million.

Karlsruhe, GERMANY – 18 November 2025
The German e-mobility tech startup, Pionix, has raised over €8 million to scale its open-source-powered products for the global e-mobility industry. Built on the EVerest stack, Pionix offers a suite of engineering and enterprise services to unify EV charging technology under a common framework. The late seed round was led by Ascend Capital Partners, with participation from Start-up BW Seed Fonds, managed by MBG Baden-Württemberg, Pale blue dot, Vireo Ventures, Axeleo Ventures and further investors.

Despite rapid development across e-mobility in recent years, EV charging remains fragmented. The industry’s growing ecosystem of hardware and software companies operates proprietary, closed software systems that often fail to communicate seamlessly with one another. Failures in interoperability and communication have led to reliability issues, inefficient maintenance of infrastructure and charging session error rates of up to 25%.

Founded in 2021, Pionix’s products offer a shared software foundation for all EV charging technologies, ensuring reliability, interoperability and future-readiness of global infrastructure. In response to the industry’s challenges, Pionix initiated and contributed significantly to EVerest, an open-source software platform. EVerest serves as a common foundation for charger manufacturers, charging operators, automakers and fleets to build on, eliminating compatibility issues and enabling faster innovation across the EV charging ecosystem.

Today, EVerest has grown into one of the most impactful open-source initiatives in cleantech and with support from 600 contributors from more than 70 organizations and powers hundreds of thousands of chargers globally.

The open-source software, donated by Pionix in 2021 to Linux Foundation Energy (LF Energy), has an estimated ecosystem value of more than $500 million – already almost half of the estimated ecosystem value of the Linux kernel, which is considered the world’s most renowned open-source project at roughly $1.2 billion.

Reshape Energy GmbH, a Munich-based building energy services business, has successfully raised €5 million in expansion capital. The funding was provided by the founding team, industry insiders, PostScriptum Ventures and Vireo Ventures, a European early-stage venture capital fund focused on electrification and digitalization. This funding round will enable Reshape Energy to complete additional acquisitions across the building energy services value chain in Germany, enhance its technology platform capabilities to drive operational efficiency and maintain high quality standards, and scale its commercial offering to capture market demand.
Reshape Energy is addressing a multi-billion-euro opportunity fueled by rising energy costs and increasing regulatory pressure on property owners across Europe. Targeting owners of property portfolios, the company simplifies the transformation of building energy performance with an all-in-one solution. By integrating assessment, planning, financing, implementation, and ongoing management and optimization, its platform enables property owners and their tenants to reduce costs, enhance property values, and achieve sustainability targets. The founding team, consisting of Alan Clifford, Andrew Goodwin, Andrew Mack, Gerard Reid, Benjamin Stanzl and Markus Wiendieck, brings extensive experience in the energy sector, having previously launched and scaled successful ventures such as the Germany business of Octopus Energy – now the UK’s largest energy retailer – and Verivox, one of Germany’s largest energy price comparison platforms. “Today’s building energy services market is fragmented and inefficient. Property owners are forced to deal with a patchwork of providers, manual processes, and limited access to financing – making energy optimization complex and costly. Our strategy is centered on acquiring and integrating businesses across the building energy services value chain to offer a one-stop-shop solution to our customers,” said Andrew Mack, CEO of Reshape Energy. “By equipping these businesses with state of the art digitalization tools, streamlined processes, access to capital, and strategic direction, we are creating a new category of energy services company that can deliver unparalleled value to property owners.” Buildings consume 35% of Germany’s energy and generate 30-40% of its CO₂ emissions, making them the EU’s largest energy consumer. Ineffi ciencies caused by outdated systems and rising energy prices are becoming an increasing challenge for German and European companies and property owners. Reshape Energy is initially focused on the German market, where it completed
the acquisitions of an energy consulting business and a commercial solar planning, installation and maintenance company. The company plans to expand its footprint across Europe in the coming years. “Reshape Energy has adopted an innovative approach to providing building energy services, and we are excited to support the company’s continued growth,” said Mischa Wetzel, Partner at Vireo Ventures. “Their deep industry expertise and commitment to sustainability align perfectly with our investment strategy. We look forward to seeing the company achieve its ambitious goals and make a significant contribution to the energy transition.”

Handwerker aus der Region, konservativer Auftritt: Wie drei Ex-Enpal-Mitarbeiter mit einem Energie-Start-up Eigenheimbesitzer bei der Modernisierung helfen wollen.

Ein Land, in dem jedes Einfamilienhaus nachhaltig modernisiert ist, ohne Stress für die Eigentümer: Mit dieser Vision gehen die drei Gründer Sebastian Schmidt, Niclas Kern und Adam Khenissi an den Start. Ihr Start-up „Deutsche Sanierungsberatung“, gegründet im vergangenen Jahr, soll Eigenheimbesitzern helfen, ihre Immobilie zu sanieren, von der Dämmung bis zum Solardach. „Wir sind dein zentraler Partner, wenn es darum geht, Strom- und Wärmekosten im Eigenheim zu senken“, sagt CEO Schmidt.

Für diese Mission hat das junge Unternehmen jetzt eine Finanzierung erhalten: 3,6 Millionen Euro haben die Gründer aus Berlin eingesammelt. Die führenden Investoren sind der Berliner Energietechnologie-Investor Vireo Ventures und, ebenfalls aus Berlin, IBB Ventures, bekannt etwa für Investments in den Heizungsbauer Thermondo und die Sprachlernplattform Babbel. Die Finanzierung soll dem Start-up helfen, seine digitale Planungstechnik auszubauen und schnell zu wachsen.

Das Geschäft haben die Gründer beim Energie-Einhorn Enpal kennengelernt. Bei dem Berliner Dienstleister, der mit dem Bau von Solaranlagen auf Hausdächern groß geworden ist, haben Schmidt, Kern und Khenissi die Sparte „Dragon“ aufgebaut.

Mit der möchte sich Enpal das Geschäft mit der Installation von Wärmepumpen erschließen.

Mit seinem eigenen Start-up macht das Trio nun seinem Ex-Arbeitgeber Konkurrenz. Doch während Enpal selbst als Installateur etwa von Solaranlagen auftritt, soll das Start-up eher die Rolle eines Energieberaters übernehmen. „Wir sehen uns als neutralen Partner von Hausbesitzern, die sie gezielt darüber aufklärt, welche Sanierungsmaßnahmen am besten geeignet sind“, sagt Mitgründer Kern.

„Deutsche Sanierungsberatung“: Schon der eher konservative Name des Start-ups soll Vertrauen schaffen – schließlich geht es bei Haussanierungen um größere Investitionen. Wer sich an das Start-up wendet, erhält erst einmal Besuch von einem Architekten oder Bauingenieur, der das Gebäude genau unter die Lupe nimmt.

Welche Sanierung rechnet sich?
Ist die Hauselektrik überhaupt geeignet, um eine Solaranlage zu installieren, oder müssen teuer neue Kabel verlegt werden? Sind die Sparren im Dach stark genug für eine neue Dämmung oder müssen sie ausgetauscht werden? Passt die Form der Dachziegel, um Solarmodule zu installieren?

Die Informationen fließen in der Zentrale des Start-ups in ein digitales Ebenbild des Hauses. Dort berechnen die Experten dann, welche Sanierung sich rechnet – von der Dämmung über den Fenstertausch bis zur wieder stark gefragten Wärmepumpe und Solaranlage. „Wir können unseren Kunden dann passgenaue Angebote von lokalen Handwerksbetrieben unterbreiten“, sagt Gründer Schmidt.

Der digitale Service soll Eigenheimbesitzern schnell ein Sanierungskonzept bieten und Handwerkern den Planungsaufwand sparen. Die Bauarbeiten sollen dann aber weiterhin lokale Handwerker übernehmen – die räumliche Nähe erlaube eine viel persönlichere Dienstleistung, sind die Gründer überzeugt. Künftig wollen die Gründer auch digitale Vernetzung etwa von Solaranlagen und E-Autos sowie smarte Stromtarife bei ihren Kunden vermarkten.

Rund 50 Mitarbeiter hat die „Deutsche Sanierungsberatung“ inzwischen. Nach der erfolgreichen Finanzierungsrunde wollen die Berliner Gründer dieses Jahr deutlich wachsen. Im vergangenen Jahr machte das Start-up knapp zwei Millionen Euro Umsatz. Unter anderem 42watt aus München und Enter aus Berlin positionieren sich mit einem ähnlichen Konzept am Markt. Der aber sei groß genug, sagt Gründer Schmidt. Bisher verursacht der Gebäudebereich 30 Prozent der CO2-Emissionen in Deutschland. Damit die auf Null sinken, müssen noch viele Milliarden Euro investiert werden.

The €2 million equity investment into the company is led by Climentum Capital with participation from Vireo Ventures and others.

Scale Energy is quickly becoming the market leader in industrial battery storage development and has secured a battery project CapEx committment for 100 MW from an energy focused infrastructure investor.

Berlin, Germany: 20 February 2025 – Scale Energy, Germany’s leading developer of industrial battery storage systems, has successfully closed an oversubscribed Seed funding round.

The equity funding is led by Climentum Capital, a European early-stage climate tech investor, with participation from Vireo Ventures as well as existing shareholders Antler and P3A. The funding will further enable Scale Energy to increase its operational footprint across Germany and accelerate the deployment of industrial battery projects.

A number of high-profile angel investors with deep industry expertise also joined the financing round, including Dr. Christine Prauschke, former Chief Digital Officer at Enpal and CEO at leadity, Henning Gebhardt, former Global Head of Equities at DWS, and Thomas Rüschen, former Deutsche Bank senior executive. Further industrial expertise comes from Frankfurt based family office SKR Capital.

Battery projects will be financed through a CapEx facility provided by a DACH based energy-focused infrastructure investor with a commitment for 100 MW.

Scale Energy is building Europe’s largest decentralized network of energy storage. Instead of building expensive greenfield storage infrastructure, Scale Energy uses existing, often underutilized grid connections to store energy in batteries and balance the power grid. Additionally, by using the storage to shift electricity consumption from high- to low-price time windows and reduce their grid fees via peak shaving, industrials enhance their energy security, lower CO₂ emissions, and meet their sustainability targets.

At a time when Europe is facing the twin challenges of rising energy costs and transitioning to renewable energy, this solution has never been more important. Energy prices in Europe are now between two to three times higher than in the US. Frontier Economics estimates that battery storage could save €12bn in electricity trading costs by 2050, while Scale Energy predicts that its solution could save German industry more than €9bn per year.

Scale Energy has already developed a project pipeline of more than half a gigawatt at more than 100 industrial sites, mainly in Germany and Austria. Existing customers of Scale Energy include paper producers, automotive suppliers and aluminum manufacturers. Any organization that has access to a grid connection of more than 1,000 Kilowatts can benefit from Scale Energy’s services.

The three founders Christoph Koessler, Nikolas Fendel and Elias Aruna combine expertise in energy operations, infrastructure financing, and engineering. Elias Aruna, CEO, comments: “At Scale Energy, our mission is to support industrials in redefining their energy use. We deliver solutions that reduce energy costs, stabilize the grid, and drive decarbonization.”

Dörte Hirschberg, General Partner at Climentum Capital, adds: “Scale Energy is not only unlocking an immense problem in the energy transition, but the team is also solving financial scaling challenges. Few companies manage early on to bundle venture and infrastructure CapEx financing into a convincing structure that enables attractive offerings for industrial customers.”
