About
Seamless.AI is a Columbus, Ohio-based sales intelligence company that provides a real-time contact search engine for B2B sales prospecting. Unlike databases that serve pre-stored contact records, Seamless.AI researches and verifies contact information in real time when a user searches for a prospect, pulling from multiple sources to assemble and validate email addresses and phone numbers as fresh as possible. The platform integrates with CRM systems including Salesforce and HubSpot and provides a LinkedIn Chrome extension for one-click contact capture. Seamless.AI offers a freemium model with a limited number of free searches, enabling individual sales reps to try the product before teams purchase enterprise plans. The company claims to be the fastest-growing sales intelligence platform, with over 500,000 users. Founded in 2016 by Brandon Bornancin, Seamless.AI bootstrapped to profitability before raising institutional funding. It competes with ZoomInfo, Apollo.io, and Lusha in the B2B contact data market with a positioning around real-time data freshness.
