Overview
Seamless.AI positions itself against database vendors such as ZoomInfo by searching and verifying contact data at the time of a lookup rather than relying solely on stored records. Its free plan provides 50 credits without a credit card, and each credit returns emails and phone numbers[10]. Paid plans have no fixed rate: Seamless.AI states that pricing depends on the number of licences, credits and additional features, and directs buyers to its sales team[10]. Buyers comparing it with ZoomInfo therefore face a similar quote-based purchasing process, although the free plan allows a limited test of data quality before any sales conversation.
