Speed to Lead Statistics: What the Research Proves and What It Does Not

Most speed to lead statistics pages are the same 20 numbers copied from each other, with no sample size, no year and no source you can open. Some of the most quoted ones trace back to a vendor press release or to nothing at all. If you are going to staff a call team around a number, you should know where it came from.

We traced every speed to lead statistic we could to its source. Here is what each study measured, how big it was, when it ran, and what it cannot tell you.

Key points

• Speed to lead statistics measure how response time to a new inquiry relates to contact, qualification or sales. Most come from a handful of B2B and B2C studies published between 2010 and 2013.
• Every study we could verify points the same way: faster first contact goes with better outcomes. The size of the effect (7x, 21x, 100x) depends on what was measured.
• The biggest loss in every audit is not the slow response. It is the inquiry nobody answers: 23% to 64% of companies or leads, depending on the study.
• No published study we found measured motivated home sellers. Investors should use these numbers for direction, then measure their own CRM.

Headline findings

These are the speed to lead statistics we could trace to a source we opened, written so you can quote them with the context attached.

• 37% of 2,241 US companies answered a web inquiry within an hour, and 23% never answered (Harvard Business Review audit, published 2011).
• Firms that tried to reach a lead within an hour were nearly 7 times as likely to qualify it as firms that waited an hour longer, and more than 60 times as likely as firms that waited a day or more (HBR data as reported by SmartCompany, 1.25 million leads at 42 companies, 2011).
• The odds of qualifying a lead were 21 times higher at 5 minutes than at 30 minutes (Lead Response Management study, 6 companies, 15,000+ leads, 100,000+ call attempts over three years).
• Average callback time was 46 hours and 53 minutes, and 35% to 64% of leads were never called in InsideSales.com secret-shopper tests of more than 10,000 companies (reported in Forbes, 2012).
• Only 60% of 3,446 companies responded to a submitted lead at all, and the average first call took 40 hours and 56 minutes (XANT, 2013).
• 63.5% of 1,000 B2B software companies never answered a demo request, while 17.2% replied in under 2 minutes, counting automated replies (RevenueHero, 2024).
• 93% of converted leads were reached by the sixth call attempt in a Velocify analysis of almost 3.5 million leads; the summary we could open does not give a year.

Speed to lead statistics with sample size, year and limits

The table below lists each statistic next to who produced it, how big the sample was, and the limit you should keep in mind before you repeat it.

Notes on each study

Each study answers a narrower question than the headline suggests. Here is what they actually did.

Harvard Business Review (2011)

The article is The Short Life of Online Sales Leads by James Oldroyd, Kristina McElheran and David Elkington. Elkington co-founded InsideSales.com. The audit and the 1.25 million-lead analysis are described in the paper, which is paywalled; we read the methods and figures as SmartCompany reported them in July 2011. "Qualify" meant a meaningful conversation with a key decision maker.

Lead Response Management study

The study page describes six companies, three years of data, 15,000+ leads and 100,000+ call attempts. It also reports that Wednesday and Thursday were the best days to reach people, and 4 to 6 p.m. the best contact window. It excluded calls from 7 to 8 a.m. and after 6 p.m., and evenings are when many sellers fill out forms.

The "100x" figure

The 100x number comes from a 2012 Forbes column by Ken Krogue, who co-founded InsideSales.com. He reports Oldroyd's finding that the odds of contacting a lead are 100 times higher at 5 minutes than at 30. The same column reports the secret-shopper results: a 46-hour average callback and 35% to 64% of leads never called.

XANT (2013) and RevenueHero (2024)

The XANT release audited 3,446 companies tied to Salesforce's Dreamforce event and found 40% never responded. The RevenueHero study sent demo requests to 1,000 B2B software companies in 2024. More than a decade apart, both found the same thing: the most common response is no response.

Call attempts and the 391%

The six-call finding comes from a Velocify summary published by The Rainmaker Institute, which also says leads needing more than seven calls were 45% less likely to convert. The 391% figure traces to a 2010 Leads360 sponsored release. It never says 391% of what, so we list it as a claim, not a benchmark.

What real estate vendors and operators report (not studies)

No published study covers motivated sellers, but two first-hand reports from public Office Hours sessions add real estate context. Each is a single source, so read them as direction, not benchmarks.

In a May 2026 session, REsimpli's founder, Sharad Mehta, said about 33% of the inbound calls in REsimpli's data are people asking to come off the marketing list, and about 10% are spam. That is vendor-reported. It means a fast answer also has to handle opt-outs cleanly.

In an August 2026 session, a nationwide Google PPC wholesaler said sellers who click will fill out eight to 10 forms and often work with whoever reaches them first. His team's goal is to be on the phone within two to four minutes, with Slack alerts at 1 and 2 minutes. That is one operator's practice.

Statistics we left out

We left out any number we could not trace to a study we could open. Two common ones did not make it.

• "Calling within 2 minutes increases conversion 300%, according to Google." We found no Google study or primary source behind it.
• "78% of customers buy from the first company to respond." Pages cite vendor blogs that cite each other. We could not find the original survey, sample or year.

If you know the primary source for either, send it to us and we will review it.

How to read these numbers without fooling yourself

Read every multiplier as "how much the odds changed in that study," not "how many more deals you will close." Odds ratios sound bigger than the real change in probability.

Here is a worked example. Say 10% of inquiries called at 30 minutes qualify. Those odds are 1 to 9. Multiply the odds by 21 and you get about 2.3 to 1, which is a 70% qualification rate. That is 7 times the rate, not 21 times. Still a huge gap. Just not the one in the headline.

Three more rules. First, these studies show correlation; companies that answer fast often do other things well too. Second, averages hide the tail, so ask for medians and the share never answered. Third, B2B buyers are not motivated sellers. A seller facing foreclosure may answer at 9 p.m. and be gone by morning.

What we see in Hesel accounts

This section is first-party data from Hesel systems. Every number below is pending sign-off and is labeled with its source, window and sample.

Read the caveats. The first four rows come from one investor account we reviewed. Most of its seller inquiries were purchased third-party leads, not Hesel campaigns, and the inquiries date from July to October 2026 unless noted. The contract rows come from our days-to-contract study of 94 contracts.

• In one investor account, the median seller inquiry got its first text or call in 1.8 minutes, and 59.7% were touched within 5 minutes, but 24.6% got no logged outbound touch within 7 days (n = 293 inquiries, July 1 to October 24, 2026).
• In windows where calls were logged, the median inquiry in that same account got a phone call in 2.1 minutes and 61.3% were called within 5 minutes, while 21.6% were not called within 7 days (n = 222, May 1 to June 23 and October 1 to 24, 2026).
• The share of inquiries called within 5 minutes in that account fell from 70.5% in May and June 2026 (n = 176) to 26.1% in October 2026 (n = 46).
• Only 17.6% of 704 outbound dials to seller inquiries in that account lasted 60 seconds or more, a proxy for a live conversation (May, June and October 2026).
• Across 94 contracts signed by 19 Hesel clients from April to August 2026, 18% were signed within 1 day of the inquiry, 47% within 7 days and 76% within 30 days.
• In the same 94 contracts, about 1 in 4 (23 of 94) came from inquiries more than 30 days old, and 5 came more than 90 days after the inquiry.
• Google-sourced contracts locked faster (median 2 days, n = 31) than Facebook-sourced contracts (median 14 days, n = 63) in that window; the Google sample is small and leans on one land investor.
• Among the 10 clients with 3 or more of those contracts, median days from inquiry to contract ranged from 1 day to 60 days.
• One client's team raised its contact rate from 29% (5 of 17 inquiries) in September 2026 to 67% (6 of 9) in the first week of October after committing to a call cadence.

What the internal data adds to the published research: speed and persistence are both visible. Fast first touches did not stop a quarter of inquiries from going untouched, and a quarter of contracts came from inquiries more than a month old. Read the real estate lead follow up guide for the cadence that covers both.

Methodology

We built this list between October 31 and November 1, 2026, using these rules.

1. Start from the statistics that rank in Google's top results and AI Overview for "speed to lead statistics."
2. Follow each one back to the earliest source we could open: the study, the study's own page, or the author's own account of it.
3. Record who ran it, the year, the sample, what was measured and any commercial interest.
4. Drop any number we could not trace. Where a paper was paywalled, we say which report we read it through.
5. Keep Hesel's internal figures in their own labeled section, with source, window and sample, pending review.

Every external study here is from a vendor, a vendor's founder or an academic working with a vendor. That does not make them wrong. It does mean you should test them on your own numbers.

What it means for real estate investors

For investors, the research says three things: answer every inquiry, answer it within minutes, and keep calling past the first attempt. Treat each multiplier as a direction to test in your own CRM, not a forecast.

• Set the clock on the first human dial, not the auto-text. Our speed to lead playbook covers the setup.
• Report the tail. The share of inquiries never called in 7 days belongs on the weekly scorecard next to cost per contract, along with the other metrics for scaling an investing business.
• Plan for six attempts or more before you call an inquiry dead, within legal calling hours.
• Match speed to channel. Search inquiries from Google Ads tend to be ready now; social inquiries often need a longer runway.
• Use ready-made scripts so speed does not cost quality. Start with our follow-up templates for seller inquiries.

Want these numbers for your own pipeline?

Published studies tell you the direction. Your CRM tells you the cost. Most investors we talk to know their cost per lead but not their median time to first dial or how many inquiries never got a call.

Hesel's conversion and appointment setting team works to a first-dial standard of 2 minutes, 5 at most. Book a strategy call and we will walk through your speed, contact rate and cost per contract with you.

Frequently asked questions

What is the average lead response time?

The average lead response time in published audits runs from about 29 hours to 47 hours. HBR found 42 hours among responders in 2011, Forbes reported a 46-hour average callback in 2012, XANT about 41 hours to a first call in 2013, and RevenueHero about 29 hours in 2024. Many companies never respond at all.

Is it true you are 21 times more likely to qualify a lead within 5 minutes?

The 21 times figure is real but often misread. The Lead Response Management study found the odds of qualifying a lead were 21 times higher at 5 minutes than at 30 minutes. That is an odds ratio from six companies, not a promise of 21 times more deals.

Where does the 391% speed to lead statistic come from?

The 391% speed to lead statistic comes from a 2010 sponsored release by Leads360, a lead management software company, reporting that companies calling within one minute saw a 391% improvement. It does not define the baseline or the method. Treat it as a vendor claim.

Is there a Google study showing 300% more conversions from calling in 2 minutes?

We could not find a Google study showing 300% more conversions from calling within 2 minutes. The figure circulates in sales training and videos without a primary source. Until someone produces the study, we recommend not using it in your own pitches or training.

How many times should you call a new lead?

You should plan to call a new lead at least six times before treating it as unreachable. A Velocify analysis of almost 3.5 million leads found 93% of converted leads were reached by the sixth call. Space attempts over several days and stay inside legal calling hours.

Are there speed to lead statistics for real estate investors?

There are no published speed to lead studies for real estate investors and motivated sellers that we could find. The well-known studies cover general B2B and B2C companies. That is why this page adds two labeled real estate reports from public sessions and a section of Hesel's own first-party data, pending review.

How do you calculate speed to lead?

You calculate speed to lead by subtracting each inquiry's creation time from the time of the first outbound call by a person, then reporting the median across inquiries. Also report the share answered within 5 minutes and the share never called within 7 days, because averages hide slow outliers.
