The Hybrid Model

Most successful teams use a hybrid approach:

1. AI SDR - Handles initial outreach and qualification 2. Human SDR - Takes over for qualified opportunities 3. Account Executive - Closes the deal

This maximizes efficiency while preserving the human touch for high-value interactions.
