Illuminator is an evidence based Public Sector Market Insight tool which aggregates and categorizes actual invoice data disclosed by over 1000 public sector organisations, including councils, NHS trusts, CCG’s, Emergency Services, and government departments. Porge's database includes over 96 million categorised invoices which makes it the most comprehensive and accurate source of public sector spend data. Illuminator is used by Suppliers to the Public Sector, who want to understand what their competitors are charging and how much their clients, and potential clients are spending. It helps private sector suppliers understand how to pitch bid pricing, and hence win more business.
