Rolf Schulte, Head of Venture & Growth Capital at M.M.Warburg & CO, says: "Supporting this project is exciting and very special for us because it contributes to preparing Germany as automotive hub for the future. The involvement of the German federal government represents a major cornerstone. At the same time, the partnership with CUSTOMCELLS® is an excellent example of our business approach: as a long-term partner and integral entrepreneurial bank, we support founders and growth companies in all facets and development phases, as is the case of CUSTOMCELLS®. Particularly in view of the complexity of the transaction with its many players, interests, and overlapping process steps, we can make excellent use of our range of services and flexibility as a bank."

"We founded CUSTOMCELLS® with the aim of developing customer-specific battery cells for the most demanding applications, and this is exactly what we can now realize together with Porsche," emphasizes Torge Thönnessen, CEO of CUSTOMCELLS®.

Further Financing Round Planned
In addition to advising and structuring the overall transaction, including the various sub-aspects, M.M.Warburg & CO also provided debt financing.
