What Sphere Energy does

Sphere Energy is a European AI company, founded in 2017 and headquartered in Paris (Sphere Energy SAS) with primary operations in Germany (Munich, Augsburg, Grossaitingen) and Switzerland (Zurich). The company develops the APEX AI Operating System, a physics-informed foundation AI platform that combines LLMs, time series foundation models, Physics-Informed Neural Networks (PINN), document retrieval, and collaboration tools to accelerate physical product development across the V-Model — from requirements engineering and generative CAD through simulation, testing, validation, and certification. The platform is anchored on proprietary physics-informed AI models (including the Triple-Check Framework for AI-powered certification) and a proprietary data flywheel generated by 1,500+ in-house battery test channels producing approximately 2TB of testing data weekly.

The company's commercial portfolio spans four integrated layers: (1) APEX AI OS and the HALO battery analytics platform sold as subscription software, (2) proprietary testing equipment including the ASC solid-state and pouch cell test cells (ASC-T+, ASC-X, ASC-AD, ASC-AD+, ASC-G, ASC-P, ASC-P+) and the Flowing Liquid Test Cell (FLC) family sold as hardware, (3) battery cell testing services delivered through ISO 9001 and TISAX certified lab operations, and (4) professional services for data management and AI consulting. Customer segments include automotive OEMs and suppliers, aerospace and defense, grid storage and energy, industrial manufacturing and power tools (e.g., Festool), consumer electronics (e.g., Dyson), battery materials (e.g., Umicore), and academic institutions (e.g., ETH Zurich, Fraunhofer Institute, NUS).

The business model combines enterprise field sales (quote-based for hardware and large software deployments), product-led growth (Batty self-serve trial, HALO no-code platform), and channel partnerships (DEKRA as strategic shareholder for certification authority, STACKIT for sovereign European cloud). DEKRA, Europe's largest independent technical service organization, is a strategic shareholder, and the leadership team includes co-founders Dr. Lukas Lutz (CEO), Luca Scherrer, and Daniel Alves Della Corte, with former Accenture DACH CEO Frank Riemensperger as Advisory Board Chairman. The company reports claims of compressing development timelines by up to 50%, reducing physical tests by 30%, cutting certification lead times by 40%, and reducing RFQ processing time by 70%.
