## The use case: how Sendoso deploys Amplemarket

Sendoso's BDR team uses Amplemarket's AI agents (Duo Copilot) in one platform to find buying signals, research prospects, and generate personalized multichannel sequences for outbound. They run Amplemarket for rep-led outreach alongside Clay for scaled outbound, and returned to Amplemarket after briefly trialing another vendor.
