Welcome to GBG, the new home of Transactis

On 1st November 2014, CDMS t/a Transactis was acquired by GBGroup, further enhancing its identity intelligence propositions with a rich data asset, derived from understanding the shopping habits of over 40m UK citizens. Together we offer client organisations the ability to support genuine customers with enhanced levels of service. On 1st April 2015 all Transactis business and assets were transferred to parent company GB Group plc.

We put relevant data at the heart of your decision-making and provide the capability to identify, understand, maintain and grow the relationships you have with the customers who drive your organisation's performance.

Our expertise lies in our ability to draw the multiple sources of data together to create an actionable picture of every individual your organisation deals with.
