About SigDiff

SigDiff was set up by Tony Isaacs in December 2007. Claire Gregory joined in November 2008.

Claire and Tony each have 20+ years experience of quantitative research, data modelling and analytics gained both client- and agency-side. Previous employers include Tesco, Mars, Unilever and HSBC. During 7 years at their previous agency, they worked (often together) with most of these companies and with other major organisations like Vodafone and Zurich Insurance.

Both Claire and Tony have Maths degrees from top universities and Masters in Operational Research.

If you work with SigDiff, your project will be led by either Claire or Tony. They will be your point of contact and will be personally responsible for all deliverables, although trusted partners may provide support in some areas such as fieldwork.
