Most teams respond to slow lead follow-up by hiring another SDR. The data usually says the problem is routing: the right lead is sitting in a shared inbox while the wrong person gets pinged first.
The 90-second window
Inbound conversion curves drop sharply after the first few minutes. Not because buyers are impatient — because competing vendors respond faster and context is still hot.
When we instrument lead queues, the median "time to first human glance" is often 40–90 minutes. The fix is rarely more people. It is a router.
Design the agent as a router
A speed-to-lead agent should qualify, score, and route — not close. Scope stays narrow: read the inbound signal, match against ICP rules, assign owner, and nudge within SLA.
Escalation is to the on-call AE when fit is ambiguous. KPI is qualified-to-booked rate or time-to-first-touch, not messages sent.
Treat inbound like a queue with SLAs, not a pile of emails waiting for someone to feel motivated.
What we wire on day one
Production speed-to-lead systems share the same integration spine.
- Form or inbox trigger within seconds of submission.
- CRM match and dedupe before any outbound action.
- Calendar availability check for the assigned owner.
- Audit log of every routing decision for weekly review.
