Grant Thornton advises Rantum Capital

Frankfurt, 12 November 2026

The Rantum Private Equity Fund II, advised by Rantum Advisors GmbH (“Rantum Capital”), is systematically continuing the strategic expansion of its medtech group in the field of premium surgical instruments. After Rantum Capital laid the foundation for the group in April 2026 with the acquisition of Tontarra Medizintechnik GmbH, it acquired two additional manufacturers of surgical instruments: S. u. A. Martin GmbH & Co. KG and Getsch+Hiller Medizintechnik GmbH. These acquisitions strengthen the Group’s market position, add high-growth premium segments to its product portfolio, and expand its customer base. To finance the acquisitions, the Group has secured new growth financing, which also provides the framework for further targeted acquisitions.

An interdisciplinary team from Grant Thornton in Germany, led by partners Klaus-Martin Haußmann (Financial Advisory) and Dr. Achim Kestler (Tax Advisory), provided comprehensive support to Rantum Capital in building the group. The services provided included financial and tax due diligence on the acquired companies, as well as the preparation of a combined financial databook for Tontarra, S. u. A. Martin, and Getsch+Hiller to support the acquisition financing. With analyses of quality of earnings and net financial debt, as well as a consolidated view of customers and suppliers, the databook provided a uniform financial basis for investors and financing partners. This engagement follows on from Rantum Capital’s advisory work on the acquisition of Tontarra Medizintechnik GmbH.  Rantum Capital, headquartered in Frankfurt am Main, is a German financial investor focused on private equity and private debt investments, specializing in long-term equity stakes in medium-sized companies across various industries in the DACH region. 

Rantum Capital’s MedTech Group manufactures precision surgical instruments at four locations with nearly 300 employees. The product portfolio covers open and minimally invasive surgery, endoscopy and spinal surgery, arthroscopy and laparoscopy, as well as microsurgery and neurosurgery. As a fully integrated OEM and contract manufacturer, the group covers the entire value chain—from development and manufacturing to certified market launch. It primarily supplies international medtech OEMs.
