Information Arts will introduce a new range of data and insight services for users of the database, which allows technology and telecommunication companies to execute marketing campaigns and build sales pipelines.
The data provides a view of the technology lifecycle of businesses within the UK and across Europe.
Built and maintained through regular telephone research, CiTDB has the capability to profile more than 2.2m IT decision makers from 750,000 business in 25 countries.
It also delivers insight data for decision makers expressing interest in all areas of IT and telecoms.
Simon Lawrence, chief executive of Information Arts, said: "This kind of specialist insight data will ultimately give technology marketers the intelligence edge. It is our aim to ensure that business-to-business marketers have the right data products in order to effectively execute marketing campaigns in the IT, telecoms and technology sectors.
"We will be integrating the database into our existing Pan European database warehouse OMNI, but also specifically using the data held within CiTDB to develop a series of analytical products and models for marketers targeting the SME sector."
Effective from August, Information Arts has taken on the existing Harte Hanks UK sales team as part of the agreement.
The announcement follows the launch by Information Arts of a number of new products including the OMNI Pan European database alongside the boosting of its client portfolio with Cisco Systems, Vonage and Vodafone.
