The open-source video conferencing solution OpenTalk can be flexibly and reliably integrated into everyday digital life—whether in the home office, in the classroom, or in job interviews.

With the appointment of Jutta Horstmann as Co-CEO, the Heinlein Group is sending a clear signal: expanding technological resilience and designing an open, secure communications infrastructure for Germany and Europe are at the top of our agenda.

The decision between cloud and on-premises has long since become a strategic issue—especially for organizations that value data protection, digital sovereignty, and full control over their IT.

From September 30 to October 2, 2025, the Berlin Exhibition Grounds will once again become the meeting place for everyone who wants to actively shape the digital future of the public sector.

OpenTalk has completely redesigned its Outlook add-in, focusing on future-proof technologies that enable seamless integration into existing IT infrastructures.

At the joint booth, we will present our solutions for digital communication – openly, transparently, and with a passion for good software.
