How fast should you respond to an inbound lead?
Short answer
Faster than 42 hours, which is the median for B2B SaaS. Aim for under an hour, and treat under five minutes as the target for high-intent enquiries. The exact number matters less than having an owner and a fallback path. Most delay comes from nobody being responsible, not from people being slow.
Why the usual advice is unhelpful
Most answers to this question cite a study claiming enormous conversion lifts from responding within a minute. That figure comes from Velocify, around 2012, measuring mortgage, insurance, and education leads. It is repeated constantly in a B2B SaaS context where it was never measured, and frequently misattributed to a different study entirely.
We removed it from our own homepage for exactly that reason.
What the data does support
The most useful sourced B2B SaaS benchmark is a secret-shopper study of 433 companies: median first reply 42 hours, and 55% never replied at all. It is from 2017 and the publisher has taken it offline, which is a real limitation. But it establishes something more useful than a target: the bar is on the floor.
You do not need to respond in sixty seconds to beat the field. You need to respond at all, reliably.
The real problem is ownership, not speed
When we read what practitioners actually write, almost none of it is about people being slow. It is about leads having no owner:
“How do you handle lead routing once you have 1,000+ inbound leads/month?”
“Broken lead routing system deletes 300 high intent inbound leads across multiple channels.”
“Where does your sales follow-up break first: demo requests, trials, or proposals?”
The pattern is structural. A lead arrives outside hours, or the assigned rep is on holiday, or a duplicate overwrites the original, and nothing catches it. Nobody was slow. The lead simply never reached a human.
A practical target
- Every lead has a named owner within a minute of arriving. Automatic, not manual.
- Every owner has a fallback for out-of-hours, holiday, and overload.
- Measure time to first human reply. An autoresponder in two seconds is not a response time, and counting it will make your numbers look excellent while your pipeline does not improve.
- Then worry about whether that is five minutes or fifty.
If you want to know where you actually stand rather than where you think you stand, the Lead Response Grader scores the routing structure, not the intention.
What this is based on
-
Median time to first reply was 42 hours across 433 B2B SaaS companies, and 55% never replied at all within five business days.

In 1,157 posts from B2B sales practitioners, the delay is consistently described as an ownership problem, not a speed problem: 'nobody owns them after 6pm', 'broken lead routing deletes 300 high intent inbound leads'.
What we don't know
- · The 42-hour benchmark is from 2017 and its publisher removed the original report. We use it because it is the only sourced B2B SaaS baseline we have, not because it is current.
- · We have no data on how response time varies by deal size, industry, or lead source. Anyone quoting a single universal number is guessing.
- · Whether faster response causes more revenue, or whether teams that are good at one are simply good at both, is not something this data can separate.
