Many have known us this way for a long time, and now it's official: phonebridge GmbH is renamed sync.blue GmbH. What was previously primarily a product name is now also becoming the company's identity. Because sync.blue® has long been more than just a brand – it's what we stand for.

Why the renaming to “sync.blue GmbH”?
Quite simply: our customers have known us for years under the name sync.blue®. sync.blue® has established itself as the leading platform for contact management – supported by a team working across Germany that has actively shaped this development. It is therefore only logical that we also anchor this identity legally. The new name creates clarity, strengthens the brand, and shows at a glance what we are all about: efficient contact management for businesses.
sync.blue® remains what it is – the leading tool for contact management
The change of name does not affect our services, support, or technology. sync.blue® remains the proven cloud solution for centralized contact management, reliably synchronizing business contacts from over 80 different systems. Whether Microsoft GAL, public folders, CRM systems, or mobile devices such as iPhone or Android – our platform ensures that all contacts are available where they are needed. Secure, GDPR-compliant, and operated on certified infrastructure in Germany.
“For many, sync.blue® has long been synonymous with modern contact management—it's no coincidence that companies such as Deichmann, Rotkäppchen-Mumm, and Deutsches Rotes Kreuz place their trust in us. The rebranding is therefore much more than just a name change: it stands for stability, technological advancement, and our clear commitment to the brand and its values.” – Oliver Baltz, CEO
Management-level reinforcement for sustainable growth
At the same time, we are delighted to expand our management team: Jonas Hönge, long-standing COO and therefore very familiar with the company and its customers, complements the management team with his experience and will accompany sync.blue® on its growth path.
“The further development of our platform and structures is a key component of our growth. I am delighted to be actively involved in shaping this path and to offer our customers even greater efficiency and stability in the future,” says Jonas Hönge.
More than two decades of experience – with a clear focus on the future
Since 2003, the team has been developing solutions that help companies manage and synchronize their contacts. What began as a small address book solution is now a scalable platform that automates, simplifies, and secures contact management.
As modern business address book software, sync.blue® helps organizations synchronize their company contacts, avoid duplicate data maintenance, and maintain an overview – in every app, on every device.
A clear signal for the future
With our new name, we are sending a clear message: clarity, continuity, and further development. sync.blue® stands for smart technology, transparent processes, and partnership-based collaboration. And that is exactly what we want to continue to build on in the future.
If you have any questions about the name change or would like to learn more about sync.blue®, we look forward to hearing from you.
