IntelliClear makes segmentation models come alive by developing tier classification gearboxes that allow clients to segment publicly available marketing lists (such as Dun & Bradstreet) into one or more of the segments of a segmentation model. By doing so clients can develop lists of potential sales targets by segment for direct marketing engagements. Dr. Alex Kalamarides is one of the pioneers of tier classification gearboxes and has evolved his experience and know-how into the custom development of these powerful marketing tools for IntelliClear clients.
