from us - for your company

We, Heike and Rolf Cremer, founded the phi 1999, to work together with our employees
to make the EDP of companies and organisations 'invisible' in the best sense of the word.

In a personal discussion among entrepreneurs, we develop an EDP concept so that you
no longer have to think about your software and hardware. It just runs; at your place or at the
phi computer centre. Your entrepreneurial demands on EDP, which are not foreign to us as entrepreneurs ourselves, are the focus of the discussion.

We look forward to getting to know you.

Heike Cremer & Rolf Cremer
