Real-Time Contact Search

Seamless.ai

Seamless.ai

Seamless.AI's real-time search engine allows users to find verified B2B contact information including email addresses, direct dial phone numbers, and mobile numbers for decision-makers at target companies. Unlike traditional databases that rely on pre-collected data that becomes stale over time, Seamless.AI uses AI algorithms to search, verify, and validate contact information at the moment of request. Users can search by company name, job title, location, industry, company size, and other firmographic criteria. The platform's AI engine cross-references multiple data sources and applies proprietary verification algorithms to ensure the contact information is current and accurate. This real-time approach means users get the most up-to-date information available, significantly reducing bounce rates and improving connection rates for outreach campaigns. Eliminates wasted time on outdated contacts and increases email deliverability and phone connection rates by 3-4x compared to static databases.
