What Fractal Energy does

Fractal Energy is a French DeepTech startup founded in 2021 and headquartered in Tours, France, operating as FRACTAL ENERGY SAS with share capital of €19,999. The company specializes in smart Battery Energy Storage Systems (BESS) integrated with an AI-powered Energy Organizer platform (Flexbox Series) that performs real-time optimization of energy consumption, production, and grid flexibility. Its hardware portfolio comprises the FlexHome LV single-phase series (5.1kWh to 19.8kWh, priced €4,615 to €7,600) and the FlexHome HV three-phase series (7.6kWh to 19kWh, priced €5,699 to €8,375), all-inclusive of VAT, delivery, installation, support, warranty, and grid services. The Energy Organizer delivers Demand Load Management, subscribed power reduction, grid connection optimization, and flexibility aggregation that pools distributed assets into price-maker communities participating in explicit and implicit flexibility markets.

Fractal Energy operates a dual go-to-market model. On the residential side, customers purchase FlexHome systems directly through the company's e-commerce website with Mollie payment integration and bundled installation, with active shipping in France, Belgium, and the Netherlands. On the commercial side, the company provides advisory-led, end-to-end engagement to Charging Point Operators (CPOs), fleet managers, and renewable energy producers, with the Energy Organizer performing 24/7 optimization and routing flexibility into energy markets. Recurring managed-service revenue is generated through ongoing monitoring and optimization, alongside grid services revenue from flexibility market participation.

The company has assembled a broad multi-country regulatory certification stack including VDE-AR-E 2510-50, IEC/EN 62109-1&-2, IEC62619, CEI 0-21 (Italy), VDE-AR-N 4105 (Germany), G98/G99/G100 (UK), and EN 50549-1, alongside compliance with EU Battery Regulation 2023/1542. Key disclosed partners include Bpifrance and Vertigo (financing), Stedin (Dutch DSO pilot for grid congestion), NFIA (Netherlands market entry), Telecom ParisTech (research), STATION F (startup ecosystem), and Centre Val de Loire and Dockwize. The company has raised approximately $2.1M in disclosed funding as of September 2023, has 1-10 employees, and is led by President Fabien Berger. No revenue is publicly disclosed.
