DEALCIRCLE with 7-digit financing round

The Hamburg-based M&A fintech DEALCIRCLE is strengthening its position as a digital ecosystem for company sales. As part of a current financing round, heise ventures is joining as a strategic partner. With the participation of existing investors, including the InnoVentureFonds of the Hamburgische Investitions- und Förderbank (IFB), the total volume of the round is in the single-digit million range.

Two proven industry experts are also participating in DEALCIRCLE. Stefan Eishold, founder and Managing Partner of private equity investor ARCUS Capital, and Mark Miller, founder and Managing Partner of international M&A boutique Carlsquare.

Focus on digital company succession in the SME sector

A central component of the strategic partnership with heise ventures is the further expansion of Deutsche Unternehmerbörse (DUB.de), which DEALCIRCLE acquired in mid-2025(we reported). DUB.de is considered the independent online platform with the widest reach for corporate transactions in Europe.

The combination of DUB.de, DEALCIRCLE technology and the automated sales platform AMBER creates an integrated infrastructure that is designed to make succession processes in the SME sector in particular more efficient, transparent and successful.

Synergies with heise platforms and SME access

The participation of heise ventures aims to leverage synergies between the strong SME penetration of heise regioconcept and other heise platforms such as guenstiger.de and geizhals.de and the transaction ecosystem of DEALCIRCLE.

Around three quarters of small and medium-sized companies face the challenge of finding a suitable successor. With heise, we have gained a partner who shares our vision of modern, data-driven company succession.

While heise has broad access to medium-sized companies, DEALCIRCLE provides the technological infrastructure for structured, data-driven company sales.

heise ventures strengthens its own ecosystem

The investment is also strategically relevant for heise ventures. Johanna Heise, CEO and Co-Founding Partner of heise ventures, says:"With our involvement in DEALCIRCLE, we are not only strengthening the SME sector, but also expanding our own ecosystem. Thanks to our proximity to the German Entrepreneur Exchange, we will also be able to support our customers in the future with the success-critical topic of company succession."

In addition to heise ventures, the participation of Stefan Eishold and Mark Miller brings additional strategic expertise to the company. In particular, Eishold strengthens DEALCIRCLE's positioning vis-à-vis institutional investors and private equity buyers. Miller supports the company in the internationalization of the network and in future strategic growth steps.
