Speed-to-lead
Speed-to-lead is how fast a business responds to a new inquiry after it comes in. Research from MIT and InsideSales found that leads contacted within 5 minutes convert far better than those contacted after 30+ minutes — in practice, whoever responds first usually keeps the conversation.
Most businesses lose leads not because the ad or the offer was wrong, but because the follow-up was too slow. A lead lands in an inbox, waits for someone to notice it between other tasks, and by the time a human replies, the prospect has often already talked to a competitor who answered first.
This gets worse at scale: the busier a team is, the slower average response time gets, right when the business can least afford to lose leads it already paid to acquire.
AI follow-up systems close that gap by responding to every new inquiry within seconds — day or night — answering initial questions and qualifying the lead before handing off a conversation that's actually ready for a human.

FAQ
What counts as a fast lead response time?
Under 5 minutes is the benchmark from MIT/InsideSales research. AI follow-up systems typically respond in under 60 seconds, which is faster than almost any team can sustain manually across every inquiry.
Does speed-to-lead matter more than ad targeting?
They're not competing — but a business fixing slow follow-up before scaling ad spend usually sees a bigger jump in results than a business increasing spend while follow-up stays slow. Faster ads don't fix a lead that waited two hours for a reply.
