Synergies between DEALCIRCLE and heise tipped the scales

The investment is rounded off by industry experts Stefan Eishold, founder and managing partner of private equity investor ARCUS Capital, and Mark Miller, founder and managing partner of M&A boutique Carlsquare. In June 2025, DEALCIRCLE already announced a financing round of around 5 million euros. One focus of the new collaboration is the online marketplace for corporate transactions Deutsche Unternehmerbörse (DUB.de), which was acquired by DEALCIRCLE in mid-2025. While the media company heise has access to small and medium-sized enterprises (SMEs) through its marketing platform heise regioconcept, among other things, DUB.de, in combination with DEALCIRCLE's technology and the startup's sales platform for business succession AMBER, provides the infrastructure for organising succession processes.    

DEALCIRCLE was founded in 2018 by Kai Hesselmann and Graig Gröbli. The startup's matching software automatically generates a detailed list of potential buyers for company successions. All data is handled in accordance with the highest security standards. Together with the fully automated sales platform AMBER and DUB.de, DEALCIRCLE forms a comprehensive ecosystem for company succession in European SMEs. The DEALCIRCLE Group placed around 4,000 M&A projects in 2025 and aims to market more than 5,000 projects in 2025.

“Around three-quarters of small and medium-sized enterprises face the challenge of finding a suitable successor. In heise, we have gained a partner who shares our vision of modern, data-driven business succession. By connecting our platforms with heise's enormous reach, we are creating real added value for owners of German SMEs.”
Kai Hesselmann, co-founder and managing director of DEALCIRCLE
