Don't hire SDRs until founder-led outbound has proven the message. First SDR hires should be senior; later hires can be junior with strong managers. Pod structures (3–5 SDRs per AE/manager) scale cleanly.
Pre-hire validation
Founders or first AEs prove the message and motion. Without that, SDRs are throwing darts in the dark.
First hires
Senior SDRs or SDR managers. They set culture and build playbooks. Don't start with juniors.
Pod structure
3–5 SDRs per pod, 1 AE per pod, 1 manager per 8–10 SDRs. Scales to 30–50 SDRs cleanly.
Common scaling mistakes
Hiring ahead of pipeline-conversion data. Removing managers when growing fast. Treating SDRs as fungible.
How SendroAI Fits In
SendroAI lets small SDR teams produce mid-team output — useful when scaling cautiously before adding headcount.
