This document discusses how companies can use behavioral scoring models built by Infer to supplement existing predictive lead scoring. By analyzing activity data like website visits and email clicks, Infer's machine learning identifies previously disqualified prospects from nurture databases that are re-engaging and likely to convert. Companies can prioritize these high-scoring "old" leads and resurface opportunities for sales. One Infer customer closed nearly half a million dollars in deals this way. The document provides examples of how companies can operationalize both fit and behavior scoring across sales and marketing.
