Seamless.AI
Real-time B2B contact search engine that researches contacts as you search
About
Seamless.AI pitches itself as a real-time search engine for B2B contacts: instead of pulling from a static database, it researches emails and phone numbers on demand, with automatic credit-back on emails its verification flags as invalid. It bundles a LinkedIn Chrome extension, buyer intent and job-change signals, plus a dialer and email outreach hub, and its API is available on every plan including free.
Honest limitations: paid pricing is quote-only and every plan is an annual term with a 60-day cancellation window — Trustpilot sits at 1.2/5, driven mostly by billing and renewal complaints. Data quality is volume-oriented rather than precision-grade, so verify contacts before large campaigns.
