Our verdict on Seamless.AI
This web-based B2B sales intelligence platform is designed for sales, marketing, recruiting, and revenue operations teams that need to find, verify, enrich, and export prospect data. Its published database size is 1.3B contacts, with business emails, phone numbers, cell phones, and direct dials. Users can filter companies and contacts by technology, industry, revenue, size, location, and job changes, then connect the results to CRM and revenue systems.
The plan structure covers both lightweight evaluation and larger deployments. The Free plan includes 50 free credits, verified email addresses, cell phones, direct dials, a Chrome extension, and export downloads. Pro is a per-user plan with unlimited exports, annual credit packages, API access, and Buyer Intent Data available as an add-on. Enterprise adds unlimited users, unlimited exports, custom packages, customer success, and enterprise support. Pro and Enterprise pricing is handled through contact-sales or custom packages rather than published plan prices.
Its strongest fit is teams that need broad prospect coverage alongside signals for prioritization. Real-time contact verification, intent topics, company and contact enrichment, job-change intelligence, AI-generated pitch and outreach content, and a REST API for search, enrichment, and synchronization extend the platform beyond basic email lookup. Integrations include Salesforce, HubSpot, Microsoft Dynamics, Zoho CRM, Keap, Pipedrive, Salesloft, Outreach, Zapier, n8n, and Clay, while the Chrome extension supports prospect research. Choose it for database scale and a wide sales workflow; teams seeking transparent paid pricing or a smaller, simpler contact lookup tool should compare alternatives.
