About Openvolt

Openvolt, founded in 2023, aimed to revolutionize energy data by developing an API framework across Europe. Before ceasing operations in April 2025, the company focused on facilitating access to smart meter data, eliminating regulatory, financial, and technical barriers for energy innovators. This ambition aligned with the global push towards achieving Net Zero goals by optimizing energy resource utilization.

Based in the United Kingdom, Openvolt was a promising player in the API and Energy industries. Attracting substantial interest from investors, the company secured a €1.50M Pre Seed Round investment on 21 September 2023, led by Cavalry Ventures and Übermorgen Ventures. Despite its promising trajectory and support, the early termination of Openvolt's operations highlights the challenges and volatility within the energy tech sector.
