Arcati offers technical and financial information and other services for the IBM mainframe community.

We work with IT vendors to help them put their message across in the European marketplace; and with users to help them get the best out of their IT investments and find the right technical resources to support their System z environment.

Arcati runs the Mainframe Market Information Service, the leading independent source of advice on IBM mainframe hardware and software acquisitions. We also publish the Mainframe Yearbook, an annual reference work for the z/OS and z/VM community.
