Cellbox Solutions GmbH, a Germany-based warm-chain logistics technology company, has completed the first closing of its Series A financing round, raising approximately EUR 3.5 million. The round is led by the digital business angel network Companisto, together with existing investors including NRW.BANK. This Series A round remains open for additional tranches until May 2026. The new capital will be used to expand international production and sales activities and to unlock further application areas, particularly in cell and gene therapy and in vitro fertilisation (IVF).

Cellbox develops portable CO₂ incubators (Cellbox™) for the safe transport of living cell samples. Its patented warm-chain technology enables continuously controlled shipment conditions for up to 48 hours, preserving cell viability and functionality during transport. The systems are certified and compliant with IATA regulations for air transport, and more than 300 devices are already in use worldwide by leading customers in the pharmaceutical and biotechnology industries, applied research institutions, and universities.

A key part of this growth phase is the appointment of Dr. Bernd Muehlenweg as Chief Business Officer (CBO) and Chief Financial Officer (CFO). He joins Cellbox full-time with more than 20 years of international experience in the life sciences industry. Most recently, he served as Senior Vice President and Global Head of Business Development, Cell Therapy at Evotec, where he led international commercial and strategic partnership activities in the advanced therapy space.

Dr. Muehlenweg commented: “Cellbox™ is setting a new benchmark in the transportation of living cells. By enabling safe, controlled, and reproducible transport under physiological conditions, we address a critical bottleneck in the life sciences industry. The investment round marks an important milestone in expanding our international footprint and establishing Cellbox™ as a global infrastructure standard for living cell shipment and warm-chain logistics. Our patented platform and strong regulatory positioning provide an excellent foundation for global scale-up across multiple life sciences applications, including the rapidly growing field of cell and gene therapies. I look forward to further strengthening our commercial operations, expanding our service portfolio, and building the organizational structures required to support the next phase of international growth.”

Dr. Robin Ghosh, Investment Manager at Companisto, said: “Cellbox™ addresses a structural gap in the life sciences value chain: the reliable transport of living cells at physiological conditions. As advanced therapies scale globally, logistics becomes a critical success factor. We view Cellbox™ not as an incremental product innovation, but as a scalable platform with the potential to redefine how sensitive biological materials are transported across research and clinical environments.” Companisto will actively support Cellbox in its next growth phase, contributing capital and targeted strategic expertise for international scaling as a fully digitalised business angel network.

Prof. Dr. Kathrin Adlkofer, Founder and CEO of Cellbox, stated: “Our vision is to redefine how living cells are transported globally. With the continued support of our investors and the strengthening of our leadership team with a highly experienced executive, we are building the foundation for long-term international growth and expanding the reach of warm-chain logistics across clinical and research applications. We are convinced that reliable live-cell transport will become an essential component of the global life sciences value chain.” In the long term, Cellbox aims to establish warm-chain logistics as the preferred global approach for transporting living cells, cell therapies, and sensitive biological materials, supporting greater reliability and reproducibility across the life sciences sector.

Founded in 2017, Cellbox Solutions provides warm-chain logistics solutions for sensitive biological materials and therapeutics that cannot be frozen and require controlled physiological conditions. Its portable CO₂ incubator platform creates a regulated environment for transporting living cells, organoids, tissues, and other advanced biological materials, with individually adjustable temperature and CO₂ levels to ensure reproducible incubation conditions throughout shipment. Cellbox systems are deployed globally and support research, clinical, and advanced therapy applications. Companisto, the lead investor, is a digital business angel network that enables private and institutional investors to participate in venture capital investments in innovative growth companies and supports them with capital, expertise, and an investor community.
