Relationship intelligence software helps make connections across accounts and people useful to sales work. Compared on network data sources, relationship history, and relationship scoring, these entries can be weighed by how they surface connections and describe their relevance. Warm intro paths and team visibility offer further points to consider, while account engagement and CRM writeback relate to how relationship information connects with sales activity. Free plan availability and paid-from pricing provide cost context. Connect The Dots, Happenstance, and Draftboard are among the options, alongside Introd and 4Degrees.
