Seamless.AI Review: Features, Pricing & Alternatives

What is Seamless.AI?

Seamless.AI is a B2B lead generation platform that finds contact details for prospects. Rather than relying only on a static database, it describes itself as a real-time search engine that researches and verifies emails and phone numbers when you search. Its site cites more than 1.8 billion verified business emails and 414 million phone numbers. A Chrome extension lets reps pull contacts while browsing LinkedIn or company websites.

Seamless.AI was founded in 2015 and is based in Columbus, Ohio. It has grown beyond contact search into a wider sales platform with buyer intent data, job change alerts, CRM enrichment and pitch intelligence. More recently it has added an engagement hub with email automation and an AI dialer, an AI Assistant, Autopilot workflows, an MCP connection and a set of AI agents for outbound, inbound, operations, marketing, customer success and recruiting.

What makes Seamless.AI different is its emphasis on fresh, real-time lookups and direct dials. It is a common choice for SDRs who mostly need phone numbers and emails fast. The trade-offs are pricing and contracts: only the free plan has a published price, paid plans are sold through sales, and many reviewers advise checking renewal and cancellation terms carefully. Data accuracy should also be tested against your own market before committing.
