What it does well

Seamless.ai describes itself as a real-time search engine for finding B2B sales leads. Its site lists contact data, outreach across email, calling and social selling, prebuilt AI agents for outbound, inbound, sales ops and other roles, and an automation network that includes an AI assistant, API, MCP, connectors, bulk credits and Autopilot. It says it integrates with 6,000+ tools.

Getting started in 10 minutes

The site says it is available on the web, through a Chrome extension for finding leads while browsing, and through apps for Claude and ChatGPT. Start with the free licence, search a narrow audience, and verify a small sample of emails and phone numbers against your own records before importing anything into your CRM.

Limits to check before you commit

The homepage mentions a free plan with up to 50 credits, but lists no paid prices and says to contact sales. The site's data volume figures are the company's own claims, so test accuracy for your market. Confirm credit terms, seat limits and API access for your plan, and make sure your outreach follows the privacy rules where your prospects live.
