Press release: Berlin-based deep tech company secures double-digit million sum for breakthrough in blood glucose measurement
BERLIN, 16th OF SEPTEMBER 2025
The investment climate in Germany remains tense: many start-ups are struggling to raise capital in the face of cautious investors, and financing rounds are less frequent and smaller than in the boom years. Projects in the medtech sector with a deep tech approach are feeling the pressure particularly keenly, with complex regulations and rising costs slowing down development. This makes the success of Berlin-based start-up DiaMonTech all the more remarkable: the company secured a total of €12 million in a financing round. As a deep tech pioneer, DiaMonTech is working on a globally unique infrared technology that measures blood sugar levels painlessly and accurately through the skin – without any finger pricks or test strips. The company recently completed a clinical study with the Institute for Diabetes Technology. For the first time, it was able to demonstrate accuracy comparable to the results of early minimally invasive devices.
High number of patents underscores the innovative power of the technology
“We have filed over 100 patents for our technology, of which more than 40 have already been granted in key markets – this demonstrates the uniqueness and potential of our approach,” says Thorsten Lubinski, CEO and co-founder of DiaMonTech. The CEO comments on the financing in this context: “The fact that we were able to raise tens of millions together with Samsung Next and other strong partners also underscores the enormous relevance of our technology – not only for the healthcare sector, but also for the entire wearables industry.”
Demand even before market entry – international expansion planned
Demand already exists even before the technology is on the market, as the CEO explains: “We already have signed letters of intent from distributors who want to pre-order 100,000 devices.” A business angel financing round of €8 million via the Companisto network was oversubscribed within a very short time – so quickly that the round had to be closed early. A total of around €35 million has been invested in the start-up to date. The award-winning scientific expertise is already proving its worth. The company has already received several prestigious awards, including the “Health-i Award” from Handelsblatt and Techniker Krankenkasse, as well as the “Deep Tech Award” from the Berlin Senate. The fresh capital will be used to accelerate the next development steps for the portable “D-Pocket” – the handy blood glucose meter – to advance clinical trials and to prepare for international expansion. In an environment where many start-ups are struggling for financing, this round sends a strong signal: it proves that investors are willing to back genuine innovations in the medtech sector even in a challenging market – and could mark a turning point in diabetes care.
