Main Capital Partners acquires secure communication and digital signature provider procilon Group from Harald Quandt Industriebeteiligungen

As a strategic partner, Main will support procilon in its next growth phase through both organic and inorganic initiatives. The acquisition marks the 4th platform investment for Main since the inception of its new fund MC VIII in April 2024.

Founded in 2001 in Taucha bei Leipzig, Germany, procilon employs ~85 employees and develops secure communication and digital signature software. procilon offers a broad software suite for the public, regulatory-driven, and private sectors, serving over 2,200 customers. The company has established long-standing relationships with essential public entities (i.e. Bundesnotarkammer) and regulatory-driven organizations, as well as large private enterprises (i.e. Telekom, Eurowings, Swisscom). With its modern cloud platform, procilon is well-positioned to meet evolving regulatory standards and drive long-term growth in regulated markets such as utilities, healthcare, and the public sector. Products like the AS4 communication standard for utilities demonstrate strong demand for the company’s innovative solutions. As cybersecurity and compliance demands continue to increase, procilon’s technology and domain expertise ensure it is poised to capitalize on these market dynamics.

The current management team will collaborate closely with Main to drive procilon’s next phase of growth. Security software is a core market for Main Capital Partners, and this partnership will leverage Main’s extensive experience in this space to support procilon’s organic and inorganic growth initiatives. With a proven track record in scaling software companies and fostering international expansion, Main brings deep expertise in regulated markets and cybersecurity. Together, the focus will be on strengthening procilon’s position as a leader in secure communication and digital signature solutions, enhancing its innovative product offerings, and unlocking new opportunities, all while maintaining exceptional customer-centricity.

Dirk Czepluch, CEO of procilon, said, “We are thrilled to partner with Main Capital Partners as we continue our mission of delivering secure and innovative solutions for our customers. Main’s deep understanding of the German public administration sector and their experience in regulated markets make them the ideal partner to support our growth journey.”

Gregor Harald May, Managing Partner at Harald Quandt Industriebeteiligungen, adds, “procilon has built a leading software platform that plays a vital role in protection of sensitive digital data, data protection and information security. Main will help procilon to continue this success story and expand the company’s reach, benefitting employees and its customers.”

Sven van Berge, Managing Partner and Head of DACH at Main, concluded, “Having followed procilon’s journey for many years, we are delighted to formalize this partnership. procilon’s strong market position, coupled with the increasing cyber-attacks on sensitive digital data, offers immense potential to expand the company’s position, also internationally. With our shared focus on organic growth and targeted acquisitions we aim to strengthen procilon’s value proposition and position the company for long-term success.”
