Lead Scoring & Signals is Apollo.io's AI lead-scoring product for prioritizing sales prospects.
Lead Scoring & Signals is a product of the Apollo.io sales intelligence and engagement platform. It generates artificial-intelligence fit scores for contacts and accounts using data drawn from a customer's CRM and prior Apollo account activity alongside demographic, firmographic, and behavioral data. Teams can also build custom scoring models by defining their own criteria, weightings, and variables.
Scores update in real time across Apollo's contact and account search results, letting sales teams filter and prioritize prospects by score. The product discloses the criteria behind each evaluation so representatives can see how a score was derived, and Apollo markets it within its Build Pipeline product suite for revenue teams.
