What is Seamless.AI?
Seamless.AI is an AI-powered B2B sales intelligence platform that finds verified emails, direct dials and company data for prospects. Instead of acting only as a static database, it describes itself as a real-time search engine that researches contacts when you look them up. The company says it holds more than 1.8 billion business emails and over 414 million phone numbers.
The product has grown from a contact finder into a wider sales suite. Seamless.AI groups its tools into a data engine for finding and enriching leads, an engagement hub for emailing, calling and social selling, and an automation layer with AI agents and Autopilot workflows. A free tier with 50 credits lets you test it, and paid plans are custom-quoted through sales. The company also runs an Academy with training on prospecting and using the platform well.
