“We operate in a market characterized by high dynamics and increasing complexity. For us, this means not only achieving growth, but translating it into a resilient structure that will endure over the long term. It is precisely at this intersection of strategy, organization, and finance that we are strengthening our leadership team with Thomas Funke. Strong financial management is critical to the sustainable development of our company – he will play a central role in this regard. At the same time, we would like to thank Christoph Steffens (DTCP), who, in his role as CFO and member of the management board, has provided invaluable support during a key phase and has been instrumental in advancing the development of our finance function.”

“The digital infrastructure market is experiencing dynamic growth and is placing increasing demands on capital allocation and speed of execution. The key is to prioritize growth consistently and manage it in a targeted manner. maincubes has a strong foundation for this and benefits from its close collaboration with its investor partner DTCP. I look forward to further developing the existing structures and aligning them to reliably support the company’s next phase of growth.”
