Seamless.AI
DataB2B contact search and enrichment with built-in email, dialer and social outreach
A data platform that also sends, with real breadth across search, intent, dialer and API, sold almost entirely through quotes and annual credit packages.
Best for
Sales teams that want contact data and the sending, dialing and social steps that follow it inside one subscription, and are comfortable buying through a sales conversation.
Not great for
Buyers who need a published price and a month-to-month exit, since everything above the 50-credit free tier goes through sales on an annual package.

Seamless.AI, in plain terms
Seamless.AI is a B2B sales intelligence platform that positions itself as a real-time search engine rather than a static list, verifying contact details when you look them up. The data side, which the company calls its Data Engine, covers Prospector for finding leads, Buyer Intent, Job Changes, CRM Enrich and Pitch Intelligence, and the marketed coverage is 1.3B+ verified contacts and 121M+ companies, with 1.8B+ business emails and 414M+ phone numbers claimed on the homepage. An Engagement Hub adds outreach on top: Connect for multichannel campaigns, built-in emailing, an AI-powered dialer and social selling. Automation covers an AI Assistant, Autopilot workflows, bulk credits, a REST API that became available on every plan including Free in May 2026, and an MCP server, plus a Chrome extension for finding contacts while browsing. Integrations are marketed at 6,000+ tools, largely routed through Zapier, with native ties to n8n and HubSpot's Breeze Prospecting Agent. Access is metered in credits, one credit per contact researched, and only the Free tier carries a published price: 50 credits for one user. Pro and Enterprise are quoted by sales with annual credit packages, which is the most common complaint alongside data accuracy. Public sentiment is sharply divided between software directories and consumer review sites.

Only the free tier has a published price: $0 with 50 credits for a single user, as of their pricing page in August 2026. Pro and Enterprise are quoted by sales and sold with annual credit packages, so the cost depends on the credit volume you negotiate. Reviewers frequently name this lack of published pricing as a frustration, so budget for a sales conversation.
A credit is consumed when the platform researches a contact to find their emails, phone numbers and insights. The free plan includes 50 credits for one user, Pro is sold with annual credit packages and unlimited exports, and bulk credits are available as a separate product for larger enrichment runs.
It depends who you ask, and the public record is two-sided. GetApp reviewers rate it 4.5 out of 5 across 571 reviews and praise fast access to contact data, while the same reviews report occasional inaccuracies and high email bounce rates. On Trustpilot the profile sits at 1.3 out of 5, with cancellation, payment and subscription among the top mentions. Test it against your own ICP before committing to an annual package.
It does both. The Engagement Hub adds Connect for multichannel campaigns, built-in emailing, an AI-powered dialer and social selling on top of the data products, so contacts can be worked without exporting them first. Exports and CRM sync remain available for teams that prefer their own sequencer.
Yes. The company made its API available on every plan, free tier included, in May 2026, and it ships an MCP server so AI tools can query the data engine directly. It also announced native workflows with n8n in July 2026 and powers HubSpot's Breeze Prospecting Agent as of June 2026.
One of these tools is ours.
Weezly is in this directory too: LinkedIn outreach with AI clone videos, a 300M+ leads database and booking, from $59 per month. See if it earns a spot in your stack.
