What Is Seamless.ai?

Seamless.ai is a B2B contact data platform. It finds verified email addresses and direct phone numbers for business professionals and exports them to your CRM or outbound tools. The core use case: a sales rep identifies a target account, uses Seamless.ai to find the right contact with a verified email and phone number, and imports that contact directly into their CRM or outreach sequence.

Who It’s For

  • SDRs and BDRs who build prospect lists manually and waste hours on outdated contact data
  • Account executives who need to find decision-maker contacts quickly at target accounts
  • Sales managers building outbound lists for the team
  • Recruiters using B2B contact data for candidate sourcing

Key Features

Real-time contact search finds and verifies email addresses and phone numbers at the time of the search rather than pulling from a static database, which reduces bounce rates on outreach.

LinkedIn Chrome extension overlays contact information directly on LinkedIn profiles, so reps can capture data without switching tabs or manually searching.

CRM integration exports contacts to Salesforce, HubSpot, Outreach, and Salesloft with one click, including company, role, and contact data properly mapped to fields.

Company intelligence surfaces company data alongside contact information: estimated revenue, employee count, technology stack, and recent funding events.

Bulk list building lets you search by criteria (job title, industry, company size, location) and export matching contacts at volume for outbound campaigns.

Pricing

Seamless.ai has a free tier with 50 credits to verify data quality. Paid plans provide higher credit volumes and additional features. See the site for current pricing and plan options.

Verdict

Seamless.ai is most valuable for sales teams where bad contact data is a measurable problem: bounced emails, wrong phone numbers, and time wasted hunting for decision-maker details. The real-time verification model makes it more accurate than tools built on static databases, though no contact data platform achieves perfect accuracy. Pair it with a dedicated outreach tool like Reply.io or AISDR for the complete prospecting-to-outreach workflow.
