Seamless.ai promises live data.
Scalelist keeps it truly fresh.

Seamless.ai delivers b2b contact data, but data is only “live” at search time — once exported, it goes stale.

Scalelist ensures accuracy with accurate b2b contact data, real mobiles, and weekly monitoring that flags job changes.

Search-time freshness is good. Continuous freshness is better.
