Seamless.AI
Real-time B2B contact search engine with AI prospecting and outreach
Last reviewed 2026-06-20
Seamless.AI is a B2B sales intelligence platform built around a real-time search engine for contact data. It finds verified business emails and phone numbers, enriches existing lists, surfaces buyer intent and job-change signals, and pushes records into CRMs. The company markets a database of (per its own homepage) 1.8B+ verified business emails, 414M+ phone numbers, and 121M+ companies. A Chrome extension captures leads from LinkedIn and company sites. Seamless.AI is sold mostly to SMB and mid-market sales teams (SDRs, AEs, founders) on a credit-based, freemium model. Its core product is assistant-grade: a human runs searches and reviews results. Newer layers (an AI Assistant, Pitch Intelligence message generation, and a set of "AI Agents" for outbound, inbound, ops, marketing, and customer success) add copilot and supervised-agent capabilities, but campaigns are configured and approved by a human, so the marketing label "AI Agents" should be read conservatively.
What it can do
Real-time B2B contact search (Prospector)
AssistantSearches a live database of business emails and phone numbers by filters like industry, headcount, technographics, and revenue; the human runs the query and selects records.
sourceData enrichment (CRM Enrich)
AssistantTakes existing lists of emails, domains, or names and fills out complete, validated contact and company profiles.
sourceBuyer intent and job-change signals
AssistantSurfaces prospects showing purchase intent and tracks personnel moves at target accounts to time outreach.
sourceAI message generation (Pitch Intelligence / Writer)
CopilotGenerates personalized outreach copy for emails and messages that the seller reviews and sends.
sourceAI Agents for outbound and outreach automation
SupervisedPer Seamless.AI marketing, agents run outbound, inbound, ops, marketing, and customer-success campaigns, including email and calling, from a natural-language brief. Campaigns are set up and approved by a human, so this appears to be supervised-agent grade in practice rather than fully autonomous.

- −The 'AI Agents' framing oversells autonomy; outreach is human-configured and approved
Overview
Seamless.AI is a B2B sales intelligence platform built around a real-time search engine for contact data. It finds verified business emails and phone numbers, enriches lists, surfaces buyer intent and job-change signals, and syncs to CRMs. It was founded in 2015 by Brandon Bornancin and Granville Schmidt and is headquartered in Columbus, Ohio.
What it does
The core workflow is assistant-grade: a seller runs a search (Prospector) by filters like industry, headcount, technographics, and revenue, then reviews and exports verified contacts. CRM Enrich fills out incomplete records, and buyer-intent and job-change signals help time outreach. On top of the database sit AI layers: Pitch Intelligence / Writer drafts personalized copy (copilot), and a set of marketed "AI Agents" run outbound, inbound, ops, marketing, and customer-success campaigns, including built-in email and calling. Those campaigns are configured and approved by a human, so the agent layer is best read as supervised-agent rather than fully autonomous.
Integrations & setup
A Chrome extension captures leads from LinkedIn and company websites and pushes them to CRMs. Native integrations include Salesforce, HubSpot, Salesloft, Outreach, and Pipedrive, plus Gmail and Outlook for sending. An API is available, primarily on higher tiers.
Pricing
Freemium with a credit-based model. There is a limited free tier (limited lifetime credits), a Basic plan reportedly around $147 per month, and Pro and Enterprise plans that are quote-based and gated behind a demo. Credit consumption and add-ons (such as buyer intent) can raise the effective cost; the figures here are reported by third parties, not all officially published.
Best for / not for
Best for SMB and mid-market sales teams that want fast, self-serve contact lookup and enrichment with a low barrier to entry. Less suited to teams that need the highest data accuracy or fully transparent, predictable pricing, where data quality and credit-based billing are the most common complaints in reviews.
Alternatives
Apollo is the closest all-in-one peer (database plus engagement). Clay focuses on enrichment and waterfall data. ZoomInfo and Cognism compete on data depth and accuracy, typically up-market.

FAQ
Is Seamless.AI an autonomous agent?+
Mostly no. The core product is an assistant-grade contact search and enrichment engine: a human runs queries and reviews results. AI message generation is a copilot, and the newer 'AI Agents' for outbound run campaigns that a human sets up and approves, so they are best treated as supervised agents, not fully autonomous.
What is Seamless.AI used for?+
Finding verified B2B contact data (emails and phone numbers), building targeted prospect lists, enriching existing CRM records, spotting buyer intent and job-change signals, and running outbound email and calling, mostly for SMB and mid-market sales teams.
How much does Seamless.AI cost?+
It is freemium with a limited free tier. A Basic plan is reportedly around $147 per month, while Pro and Enterprise pricing is quote-based and gated behind a demo. Pricing is credit-based, so real cost scales with usage and add-ons (figures are reported, not officially published in full).
