Speed-to-lead
Speed-to-lead is the time between a lead raising a hand, such as a demo request, and the first meaningful response from a person on the revenue team.
In practice
Inbound interest is perishable, and slow first responses usually trace back to routing: leads wait in a queue, match no rule or land with someone who is away. RevOps owns the rules and the clock.
Measure from the form submission timestamp to the first logged call, email or meeting by the owner, and report the median and the slowest decile rather than the average. Break it down by source, hour of day and owner to find where leads stall.
