Why us?

About Us

About Us

Circunomics GmbH, based in Mainz, Germany was founded in 2019. Circunomics is leading the industry by offering a comprehensive battery lifecycle management solution. Co-Founders, Felix Wagner and Jan Born, are dedicated to establishing a true circular battery economy, which in turn, maximizes each stage of battery life. Along with their team, they seek to inspire the movement of batteries from the automotive industry, to the energy sector, and finally on to recyclers who close the loop by recovering any remaining raw materials.

Circunomics has developed an AI-powered, B2B marketplace where cells, modules, and packs can be sold and purchased. Through the Circunomics Analytics product, sellers and buyers alike can obtain a detailed view of their assets. From current SoH to 2nd-life simulation, this product allows for a simpler and more profitable lifecycle management. Circunomics knows that lifecycle planning is complex, and the Battery Matchmakers are on a mission to help ease this process for their customers.

The company has been supported thus far by seed investors and business angels. Startup builder Next Mobility Labs, recycler TES, Orlen VC, and Dr. Peter Mertens (former Chief Technology Officer of Audi) are some of the key players. The Series A funding round was completed in December of 2024 with the addition of investors, Schaeffler and GET Fund.

Official expansion into the US Market transpired in January of 2025 with the hiring of Adam Willmouth who will serve as the company's US Managing Director. Circunomics looks forward to further collaboration with current US clients and to further growth within this key global market.
