Our process

In sigma we believe in total experience — a sum of customer, employee and user experience. None of these should be ever taken in separation, but they often are. What sets us apart is an real-life approach, that does not get bogged down in abstract theory and gets down to business.

Who we are

The unique approach of Sigma CEM is a result of a diverse background of our team. Core members have held c-level positions in international retail and blue chip organizations, in all major areas of activities (Marketing, Operations, Procurement, Services, Online etc). Whatever your business is, we probably know it in and out, and can avoid tunnel vision that often stems from limited perspective.
