Speed to Lead Statistics 2026, Every Source Checked

The short answer

Responding within minutes rather than hours makes it far more likely that you reach and qualify a lead: nearly 7 times as likely within an hour as an hour later (HBR, 2011), and 21 times as likely to qualify within 5 minutes as within 30 (InsideSales.com, 2007). Neither study measured closed deals. Most companies are still slow: in 2024, 63.5% of 1,000 B2B SaaS companies never answered a demo request (RevenueHero, 2024).

How fast do companies respond to leads?

23% never respond. In a 2011 audit of 2,241 U.S. companies, 37% responded to a web lead within an hour, 16% within one to 24 hours, 24% took longer than 24 hours and 23% never responded. (HBR, March 2011)

42 hours on average, among those that replied. The HBR average counts only companies that responded within 30 days, so it leaves out the 23% that never did. The sample was not limited to B2B. (HBR, March 2011)

63.5% of B2B SaaS companies never replied to a demo request. RevenueHero requested demos from 1,000 B2B SaaS companies. Those that replied took 1 day and 5 hours on average, and 17.2% replied instantly. About 31% of the non-responders ran lead-enrichment tools, so some may have screened the test request out on purpose. (RevenueHero, March 2024)

The top 100 SaaS companies took 2 days on average, and 35% never replied. (Chili Piper, May 2023)

7% of 433 B2B SaaS companies replied within 5 minutes, and 55% had not replied after five business days. (Drift, February 2017)

58% of 512 B2B companies never replied within five business days, and 10% replied within 5 minutes. (Drift, April 2018, archived)

1 of 114 B2B companies sent a personal email within 5 minutes. The average reply took 11 hours 54 minutes by email and 14 hours 29 minutes by phone. (Workato, September 2020)

Does responding faster actually matter?

Nearly 7x as likely to qualify within an hour. Across 1.25 million leads at 42 U.S. companies (29 selling to consumers, 13 to businesses), firms that tried to contact a lead within an hour were nearly 7 times as likely to have a qualifying conversation with a decision maker as firms that tried an hour later, and more than 60 times as likely as firms that waited 24 hours or more. (HBR, March 2011)

5 minutes versus 30: 100x the contact rate, 21x the qualification rate. The 2007 Lead Response Management study, by InsideSales.com and James Oldroyd, analysed six companies' call data: about 15,000 leads and 100,000 call attempts, mostly in mortgage and insurance. The report says it did not look at close rates. (InsideSales.com and Oldroyd, October 2007)

Calling within one minute: +391% conversion. Velocify analysed 3.5 million leads from more than 400 of its customers in the first half of 2012. The report does not say what the 391% is compared against. (Velocify, about 2013, archived)

8x higher conversion within 5 minutes. InsideSales analysed 5.7 million leads at more than 400 companies on its platform. Its materials compare against two different time windows, so treat the multiple as approximate. (InsideSales, 2021)

What buyers say they want

67% of B2B buyers prefer a rep-free buying experience, according to Gartner's survey of 646 buyers in August and September 2025. Gartner's earlier figures of 75% (2023) and 61% (2025) are superseded. (Gartner, March 2026)

17% of B2B buying time goes to meeting potential suppliers, split across every vendor under consideration. The figure no longer appears on Gartner's current page. (Gartner, archived April 2020)

Statistics to stop using

"78% of customers buy from the company that responds first." Usually credited to a "Lead Connect" survey. We could not find the survey, and every citation we followed led back to another vendor blog.

"35-50% of sales go to the vendor that responds first." Credited to InsideSales since at least 2013, but it does not appear in any InsideSales document we checked.

"51% of leads are never contacted." The InsideSales page it is credited to does not contain it.

"21x more likely to convert" or "to close". The 2007 study measured contact and qualification, not closed deals, and says so.

"The MIT study" or "HBR's 5-minute rule". The 5-minute figures come from the 2007 InsideSales.com study. The HBR article does not mention five minutes.

"42 hours is the average B2B response time." HBR's sample was not limited to B2B, and the average leaves out the companies that never replied.

"75% of B2B buyers prefer a rep-free experience" as a current figure. Gartner's latest survey puts it at 67%.

What this means for a demo request

Every study above measures how quickly a company replies to a lead, not how quickly the buyer gets to see the product. For a buyer who asked for a demo, a fast reply is often only the first step toward a call on a later day. An AI demo agent closes that second gap by running the demo when the buyer asks. Floe is one; see the full list of AI demo agents to compare them.

How we checked these numbers

For each figure we found the original source and read it; for the HBR article, a full-text copy, because hbr.org is paywalled. Where a vendor ran the study, we say so. Most speed-to-lead research comes from companies that sell speed-to-lead tools, and we found no peer-reviewed study on it. Sources checked on 26 September 2026.
