Our story

Helping members use the power of cooperative data

For 23 years we have been helping Abacus Alliance members use the power of cooperative transactional data to improve their direct marketing effectiveness and return on investment. We launched the Abacus Alliance in 1998, introducing the cooperative transactional database concept into the UK. In 2007 Abacus was acquired by global marketing innovator Epsilon, becoming part of its Marketing Services data arm.
