We Are On A Mission

Aquarray is a privately held German biotech company developing a proprietary technology platform, the Droplet Microarray (DMA), which enables highly miniaturized assays, screenings and analyzes.

Founded as a spin-off from the Karlsruhe Institute of Technology, Aquarray's technology is based on a unique surface structure that enables a dense grid of nano-volume reaction vessels.

Together, we aim to take miniaturization to a new level and provide a solution that enables the development of novel, more effective workflows and screenings in areas where the availability of reagents, materials or cells is limited, paving the way for new applications.


Aquarray is a spin-off from the Karlsruhe Institute of Technology (KIT), Germany, founded in early 2018 by Konstantin Demir, Gunter Festel, Michael Grunze, Pavel Levkin, Anna Popova, Jörg Vienken and Simon Widmaier.

The core technology was developed by Pavel Levkin in his role as Professor at KIT together with Anna Popova as senior scientist and Konstantin Demir as engineer in his working group. Gunter Festel as founding angel and serial entrepreneur and Simon Widmaier as CEO joined the team. Michael Grunze, Professor for Applied Physical Chemistry at Heidelberg University, and Jörg Vienken, R&D Director in the Biosciences Department of Fresenius Medical Care, formed the advisory board.

Important milestones were the EXIST Forschungstransfer grant and the SME Instruments grant by the European Commission which enabled Aquarray to further develop the technology. Wolfgang Sipos, former head of purchasing at Roche Diagnostics in Mannheim, as new CEO led Aquarray through this period of technological development.

In late 2022 he handed over the CEO position to Tim Friedrichson, a former Max-Planck scientist and Management team member at Jado. To speed up the commercialization process, Harry Böltz, co-founder and former CEO of Dispendix, which was successfully sold to Cellink, joined Aquarray in early 2023 as head of sales.



Dr. Tim Friedrichson has more than 20 years of experience in and with biotech startups. He holds degrees in biochemistry and cell biology. After his PhD, he held various positions in a biotech startup company and worked for Max Planck Society. He is co-founder of two startups and focuses on new technology implementation, product development and business management.
