Our history

We were founded in 2002, and have since formed into an audit and tax advisory firm with a team of 70 professionals operating in the heart of Berlin.

What makes us different?

Our culture is characterised by three key words: responsibility, passion and innovation. These are the values that guide us in our daily work as auditors and tax consultants, and the values by which we would like to be measured. They sit at the centre of our work with our clients, our dealings with business partners, and our interactions with our colleagues.
