Circunomics, GmbH was founded in 2019 and is in Mainz, Germany. The company 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 to maximize each stage of battery life. Along with their team, they seek to inspire the movement of batteries from 1st-life within the automotive industry to 2nd-life within the energy sector, and finally, through working with recyclers to close the loop by recovering any remaining raw materials.

Circunomics has developed an AI-powered, B2B marketplace where cells, modules, and packs can be traded. Through the Circunomics Analytics product, sellers and buyers can obtain a detailed view of their assets. From current SH 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 is set for completion in Q3/Q4 of 2024.
Though many customers already exist in the US market, Circunomics will officially expand its operations into the US by the end of 2024.

US-based company Frost & Sullivan awarded Circunomics the 2023 Market Leadership Award. This award identified Circunomics as the Best in Class within the European Circular Marketplace for the Battery Trade Industry.
