About 5F
The company
We are 5FSoftware GmbH, based in Regensburg, and we develop 5F, the platform that firms, companies and associations use to exchange and coordinate confidential documents with external parties. We keep development, operations and support in our own hands.
Where does 5F come from?
- Since 2018
- The platform was originally developed for collaboration in tax advisory and audit firms.
- The benchmark
- These firms are subject to a duty of confidentiality, long retention periods and the need to provide evidence to third parties. The platform has grown by meeting these requirements.
- Independent
- 5FSoftware GmbH is self-funded, without external investors, and decides for itself how 5F evolves.
The people behind 5F
In their own words, our management describe what drives them.

Andreas Baier
Founder & CTO
“In the end, it is always people working with people! At 5F, we love technology most of all when people work together. What matters most is trust: trust in us and in how we all work together in the thick of things. Don't solve problems to replace people. Solve problems because you don't have enough people in the thick of things.”

Maximilian Mann
CFO
“The more parts a system has, the more I admire simplicity. Every additional hurdle is an invitation to get around it. That is why at 5F we build secure communication that is so elegant it becomes the shortcut itself.”
