About us

Context4 Limited was formed in 2001 to meet the need for better quality business data and to develop innovative data products all aimed at helping improved business decision making. 


Major projects include:

  • Adding proprietory Context4 classification codes to D&B's business trading file so it can be used more effectively by media owners and leading B2B brands wanting a more consumer and granular classification system to SIC codes.  This has helped some of the UK's leading brands with access to their business data and created a £1M+ new revenue stream for D&B in the UK
  • Validating the SIC codes of a major business data owner to reduce the number of customer complaints and loss of business
  • Developing the Royal Mail Business Changes File (BCF) by integrating Royal Mail's business mover data with D&B and other sources of ceasing trading records.  The BCF is now established as the leading data file for improving the quality of business data creating new revenues for Royal Mail and helping it reduce poor quality business mail
  • Acquiring and developing Business Accumin the first geographic classification of business potential developed by TDS Group in 1991 with leading segmentation specialists Dunn Humby. We have recently redeveloped Business Accumin for business marketers working closely with award winning Data Scientist Dr Tim Drye.
