Seamless AI is a sales intelligence and lead generation platform founded in 2015 by Brandon Bornancin and Granville Schmidt in Columbus, Ohio. The company has raised $4.39M in seed funding from Rev1 Ventures, Right Side Capital Management, and Newark Venture Partners, growing to $43.8M in annual revenue with over 200,000 customers and 1,000,000+ total users. The core product is a real-time B2B search engine aggregating 1.7B+ verified contacts and 150M company profiles sourced from LinkedIn, job boards, news outlets, SEC filings, and direct web scraping. Unlike static data vendors that refresh quarterly, Seamless operates as a live search engine, updating profiles daily as job changes, company news, and funding announcements occur. The platform prioritizes accuracy: email verification checks mailbox availability, and phone numbers are validated against carrier databases. Key features include a Chrome extension that enriches LinkedIn profiles with verified emails, cell phone numbers, and company intelligence during prospect research. The Autopilot feature automates list-building by generating smart lists of fresh leads daily based on saved filters. Job Change Alerts notify users when decision-makers move to new companies, enabling timely warm outreach. Buyer Intent Data identifies accounts showing signals of active purchasing, prioritizing high-intent prospects. Lead Scoring ranks prospects by conversion likelihood, and Contact Enrichment backfills profile gaps with missing emails and phone numbers. The platform integrates natively with Salesforce, HubSpot, Salesloft, Outreach, Pipedrive, and Hubspot, pushing discovered contacts directly into CRM workflows. The target audience is sales development representatives, account executives, and sales operations teams at B2B SaaS companies running outbound prospecting. Seamless AI is less suitable for teams that need complete deal-stage intelligence or AI-generated outreach copy; those use cases require pairing with platforms like Salesloft or Outreach. Pricing starts with a free tier of 50 lifetime credits. The publicly listed Basic plan costs $147/month on annual billing for 250 monthly credits. Pro and Enterprise plans are quote-based, with Pro typically ranging $79-$150/user/month (5-user minimum) and Enterprise requiring custom negotiation. All plans auto-renew and require 60-day written cancellation notice. Hidden costs include add-on features like Buyer Intent Data ($79-$199/user/month) and AI Writer for outreach copy generation.

Seamless AI offers a free tier with 50 lifetime credits. The publicly listed Basic plan costs $147/month on annual billing and includes 250 monthly credits.

Seamless AI provides 1.7B+ verified contacts with daily updates, a Chrome extension that enriches LinkedIn profiles with emails and phone numbers, and job change alerts that notify users within 24 hours when decision-makers move companies. Buyer Intent Data identifies accounts showing purchasing signals. Autopilot automates daily list-building based on saved search filters. Lead Scoring ranks prospects by conversion likelihood. Native CRM integrations push contacts into Salesforce, HubSpot, Salesloft, Outreach, and Pipedrive.
Seamless AI offers a free tier with 50 lifetime credits, enough to search for about 50 prospect contacts and test the Chrome extension workflow. The free plan includes access to the core search engine and basic CRM integrations. However, the 50 credits are lifetime, not monthly, making the free plan suitable only for evaluation. To run ongoing outbound prospecting, the Basic plan at $147/month is the minimum paid tier.
The top Seamless AI alternatives are Apollo.io, ZoomInfo, Hunter.io, and Clearbit. Apollo.io provides similar contact coverage at comparable pricing with built-in email warmup. ZoomInfo offers deeper intent data and account-level insights for mid-market and enterprise sales teams. Hunter.io is cheaper for smaller teams needing email-finder-only functionality. Clearbit focuses on instant email discovery for in-flight visitor identification. For job change alerts specifically, LinkedIn Sales Navigator and GitHub's Octoverse remain unmatched.
Seamless AI is best for sales development representatives and account executives at B2B SaaS companies running outbound prospecting campaigns daily. Sales operations teams use it to backfill contact data and automate CRM list updates. Founders testing cold outreach hypothesis before scaling to a full sales team find the Basic plan affordable for validation. It is not a good fit for solo marketers on tight budgets, or sales leaders needing deal-stage intelligence and pipeline forecasting, which require pairing with sales engagement platforms like Salesloft or Outreach.
Seamless AI provides CRM integrations via Salesforce, HubSpot, Salesloft, Outreach, and Pipedrive APIs, pushing discovered contacts directly into those systems. A native REST API for custom integrations is available on Enterprise plans by request. There is no published public API documentation. MCP (Model Context Protocol) support has not been announced as of May 2026. SDK support is limited to the Chrome extension.
Seamless AI and Apollo.io are the two most-reviewed B2B lead databases on G2, with Seamless at 4.4/5 (5,096 reviews) and Apollo at similar ratings with 4,000+ reviews. Both provide 1B+ contacts and daily updates. Apollo integrates email warmup directly into the platform, helping users avoid spam folders; Seamless requires a separate warmup tool. Seamless has a stronger job change alert system that notifies within 24 hours. Apollo's pricing is often cited as more predictable and transparent. For SDRs prioritizing fresh job changes, Seamless wins; for teams needing end-to-end outbound (discovery to warmup), Apollo is more complete.
