Volteras, the leading data streaming platform for businesses in energy and mobility, today announced the close of its £8m oversubscribed Series A funding round. This milestone was led by Union Square Ventures, known for early investments in companies like Twitter, with participation from fleet card providers Wex and Edenred, alongside existing investors Exor Ventures and Long Journey Ventures. Wex and Edenred, which together service 24 million vehicles, see Volteras as a critical enabler in their transition to electric vehicles (EVs).
Volteras has taken a transparent, partnership-based approach to data integration, securing official connections with over 30 OEMs, including Ford, Mercedes-Benz and Volkswagen Group AG. These authorised integrations allow vehicle data to be streamed securely and in real time, with intervals as frequent as every five seconds and 99.9% uptime. Through these connections, energy and mobility businesses can access multi-brand vehicle data to enable fleet optimisation, preventive maintenance and smarter energy management.
The startup is redefining how data flows between EVs, chargers and home batteries. Its API connects millions of compatible devices, enabling energy companies, insurance providers, virtual power plants, fleet managers and charging networks to access vital data within days - something that might otherwise take years to establish independently. This foundation supports innovations such as EV marketplaces offering data-driven vehicle health certificates, or energy suppliers remotely controlling home energy devices to reduce strain on the grid and lower consumer prices.
Hitachi ZeroCarbon is using Volteras’ platform to launch a new charging management service that connects fleets without requiring hardware installation. This is one example of how businesses are outsourcing high-quality vehicle data acquisition to focus on innovation and customer insight.
Volteras ultimately aims to build the world’s largest energy data platform, integrating vehicles, chargers and energy devices into a single system. For consumers, this means services like usage-based insurance, smart charging that responds to grid pricing, battery health reporting and insights into the carbon footprint and renewable content of energy used at home or in vehicles. For businesses, real-time data enables fleet optimisation, predictive maintenance and more accurate balancing of grid demand.
Security is at the core of the Volteras platform. OEM-authorised data flows through encrypted channels, preventing the vulnerabilities associated with third-party or unofficial integrations. Volteras does not access personally identifiable information - only vehicle data with the owner’s consent - ensuring privacy and enterprise-grade cybersecurity. With this funding, Volteras plans to expand partnerships with automakers and energy device manufacturers globally, grow its team and support new partners like Octopus Electric Vehicles and Hitachi ZeroCarbon in launching new services.
