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.

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 Eliminates wasted time on outdated contacts and increases email deliverability and phone connection rates by 3-4x compared to static databases.

Seamless.ai

Seamless.AI provides buyer intent signals and job change alerts to help sales teams identify prospects who are most likely to be in-market for their solutions. The intent data feature tracks digital signals across the web to identify companies actively researching topics related to your products or services, scoring accounts based on their likelihood to purchase.

Users can set up automated alerts for specific triggers, such as when a contact at a target account changes jobs or when companies in their ideal customer profile show buying intent. This intelligence helps sales teams prioritize outreach efforts and craft more relevant, timely messaging. Increases conversion rates by 2-3x by enabling sales teams to reach out at the optimal moment when prospects are most receptive.
