The Brutal Truth on AI SDRs: 50–70% Churn, Hybrids Win by 2.8x

Salesmotion's April 2026 data breakdown cuts through the AI SDR hype: 50–70% of AI SDR implementations churn within a year, and fully autonomous agents convert meetings to opportunities at only ~15% versus ~25% for human SDRs. The teams actually winning are running hybrid models — AI handles research and initial volume, humans own relationship-building and complex conversations — and they're generating 2.8x more pipeline than full-replacement plays. If you're being sold a 'replace your SDR team' pitch, the data says pump the brakes and build a signal-driven hybrid instead.
