Who Actually Found That 78% of Customers Buy From the First Responder? We Traced It.
Key Takeaways
- The '78% of customers buy from the first responder' stat is attributed to a 'Lead Connect survey' by Vendasta, but no Lead Connect study document with a named methodology, sample size, or publication date has been publicly found.
- Vendasta's hyperlink on the words 'Lead Connect survey' points to a LeanData page that does not contain the 78% figure anywhere. The citation chain is broken at its most widely-cited node.
- The MIT Lead Response Management Study (Dr. James Oldroyd, 2007) is real and rigorous: it found leads contacted within 5 minutes versus 30 minutes were more than 10 times more likely to be reached and 21 times more likely to be qualified.
- Harvard Business Review's 2011 audit (Oldroyd, McElheran, Elkington) of 2,241 US firms found that responding within 1 hour made a company nearly 7 times more likely to qualify a lead than waiting even one hour longer.
- The underlying finding, that being first to respond confers a significant sales advantage, is supported by two decades of peer-reviewed and behavioral research, even if the specific 78% figure is not.
The short version: we could not find the study.
The longer version explains what we found instead, and why the underlying finding is real even when the most-cited number is not.
The Stat That Is Everywhere
"78% of customers buy from the company that responds to their inquiry first."
If you have worked in B2B sales or marketing for any stretch of time, you have seen this claim. It appears in Vendasta's lead response blog. In Chili Piper's speed-to-lead guides. In sales training decks, CRM onboarding materials, and LinkedIn posts from sales influencers who have cited it without knowing its origin.
It is the kind of stat that sounds true because it confirms what experienced salespeople already believe: get there first and you win more deals.
The problem is not with the intuition. The problem is with the number.
When someone in the citation-intent audience, whether they are a journalist, a researcher, a content marketer, or an AI tool evaluating source quality, tries to follow the 78% back to its origin, they hit a dead end. We ran that trace. Here is what we found.
Tracing the 78% Citation Chain
Node 1: Most blogs point to Vendasta
If you search for the 78% figure today, the most frequently linked source is Vendasta's "Why Lead Response Time Matters" blog post. Vendasta is a SaaS company that sells white-label software to marketing agencies. They are not a research institution. But their post is thorough, well-organized, and ranks well, which is why it became the de facto citation for hundreds of downstream posts.
Vendasta's attribution: "According to lead response time stats from a Lead Connect survey, 78% of customers buy from the company that responds to their inquiry first."
Node 2: Vendasta's hyperlink goes to the wrong place
Here is where the chain breaks. In Vendasta's post, the words "Lead Connect survey" are hyperlinked. That hyperlink points to LeanData's blog post on the modern rules of lead response time.
We fetched the LeanData page. It does not contain the 78% figure anywhere. Not in the body, not in a table, not in a footnote. The LeanData post uses only HBR-verified figures: the 7x qualification multiplier and the 42-hour average response time. There is no mention of Lead Connect or 78%.
The most widely-cited link in the 78% citation chain points to a page that does not contain the statistic.
Node 3: Lead Connect is a CRM tool, not a research institution
Lead Connect (leadconnect.io) is a LinkedIn automation and CRM company. When we attempted to fetch the leadconnect.io/blog URL to look for the original study, it returned an HTTP 404. The page does not exist. A search of the Wayback Machine archive of leadconnect.io/blog did not surface a dedicated lead response study post.
No Lead Connect study document with a named methodology, sample size, publication date, or author has been publicly located by any researcher who has specifically looked for it. This includes an April 2026 review by AInora, which explicitly states: "The widely repeated '78% buy from the first responder' and '35-50% of sales go to the first responder' claims, variously pinned on McKinsey, InsideSales, or Forrester, have no traceable primary source either."
Node 4: Chili Piper attributes the stat to a Vendasta employee, not a study
A 2020 Chili Piper article on speed to contact contains the 78% figure with an attribution that is revealing. It attributes the number to Brock Andory of Vendasta, a named employee, not to a study, a research paper, or a methodology. The figure appears as a quote in a context that implies it is a statistic from research, but the attribution is to a person at a software company.
This confirms Vendasta as the primary popularizer of the figure, not its original researcher.
Node 5: Some pages misattribute it to MIT
To make the provenance problem more complicated, a number of aggregator pages, including one we fetched directly from CaseyResponse.com, attribute the 78% figure to "Lead Response Management Study, Dr. James Oldroyd, MIT."
We fetched the MIT/InsideSales Lead Response Management Study at leadresponsemanagement.org directly. The MIT study does not contain a 78% figure. The misattribution appears to have been invented by aggregators who wanted a more credible-sounding source and reached for the most rigorous study in the space.
Node 6: The Salesforce attribution could not be confirmed
The research brief notes that a 2015 Salesforce Australia blog post reportedly attributed a similar figure to HBR. The Salesforce.com/au URL returned HTTP 403 when accessed, blocking direct verification. We cannot confirm the wording or the HBR attribution from that post. It is omitted from our citation chain as an unverifiable node.
The citation chain, visualized
| Node | Source | What they claim | What we found |
|---|---|---|---|
| 1 | Most blogs, aggregators | 78% from "Lead Connect survey via Vendasta" | Vendasta is the popularizer, not the original source |
| 2 | Vendasta | "Lead Connect survey," hyperlinked to LeanData | LeanData page fetched live: does not contain the 78% figure |
| 3 | Lead Connect | Original study presumably published here | leadconnect.io/blog returns HTTP 404; no study document found anywhere |
| 4 | Chili Piper (2020) | Attributes the stat to "Brock Andory of Vendasta" | It is a quote from a software employee, not a citation to research |
| 5 | CaseyResponse and others | Attributes 78% to "MIT/Dr. James Oldroyd" | MIT study fetched live: does not contain this figure |
| 6 | AInora (April 2026) | States 78% has no traceable primary source | Independent conclusion consistent with our trace |

What the Real Research Actually Says
Stop Losing Leads to Slow Response
Equipment buyers move fast. Memox responds in ~3 seconds, 24/7.
The absence of a traceable 78% figure does not mean the first-responder advantage is invented. Two decades of peer-reviewed and behavioral research produce a consistent finding: speed to lead dramatically increases contact rates, qualification rates, and conversion. The verified numbers are strong enough to make the case on their own.
A note on source access: the HBR 2011 article is behind a paywall and could not be verified by direct fetch of the full text. Findings are confirmed via multiple consistent secondary citations including LeanData and leadresponsemanagement.org. The Drift 2017 study's original URL (leadresponsestudy.com) no longer resolves; Drift was acquired by Salesloft. The Velocify white paper URL has rotted since Velocify was acquired by ICE Mortgage Technology. We have cited these at the confidence level warranted by available evidence.
| Study | Year | Methodology | Key Finding | Confidence |
|---|---|---|---|---|
| MIT Lead Response Management Study (Dr. James Oldroyd / InsideSales.com) | 2007 | 6 companies, 15,000+ leads, 100,000+ call attempts, 3 years of behavioral data | Calling within 5 min vs 30 min: more than 10x better contact odds, 21x better qualification odds | High: documented methodology, fetched live |
| Harvard Business Review audit (Oldroyd, McElheran, Elkington) | 2011 | 2,241 US companies audited with test web leads | Within 1 hour: nearly 7x more likely to qualify; vs 24 hours: 60x more likely; average response time: 42 hours | High: peer-reviewed, paywalled but confirmed via consistent secondary sources |
| Velocify "Ultimate Contact Strategy" white paper | 2013-2016 | Approximately 3.5 million leads on the Velocify platform | Calling within 1 minute: 391% higher conversions | Medium: large sample, vendor platform data, skewed toward mortgage/insurance/education verticals; original white paper URL no longer accessible |
| Drift Lead Response Survey | 2017 | Test-submitted demo forms to 433 B2B companies | Only 7% responded within 5 minutes; 55% did not respond within 5 business days | Medium-high: behavioral test, documented methodology, original URL dead, consistent secondary citations |
| "78% buy from first responder" (attributed to Lead Connect) | Unknown | No study document found | 78% of customers buy from whoever responds first | Not traceable: no methodology, sample size, publication date, or primary document found |
The Directional Truth: What the Verified Research Supports
The 78% may not have a traceable source, but the underlying phenomenon is real and documented. A few observations from the verified evidence:
Speed creates anchoring. When a buyer submits an inquiry to multiple vendors simultaneously, whoever responds first gets to frame the conversation. They set the buyer's expectations for pricing, lead time, and what a good answer looks like. Subsequent responses are evaluated against that anchor. This is not a hypothesis. It is the mechanism the HBR authors described when explaining why the 7x qualification multiplier exists.
The window is shorter than most businesses assume. The MIT study found that contact odds dropped by more than 10 times between the 5-minute and 30-minute response windows. The HBR study found qualification odds dropped 60-fold between 1-hour and 24-hour responses. Most service businesses are not operating in the 5-minute window. Most are not even in the 1-hour window. The Drift behavioral audit found 55% of the 433 B2B companies tested did not respond within 5 business days.
The 42-hour average is a competitive gift. A figure of approximately 42 hours appears consistently across industry sources including the HBR audit and the Drift survey. If you respond in under an hour, you are ahead of the vast majority of competitors, regardless of what the exact 78% figure says.
The verified numbers are more conservative than 78% and more useful. "Nearly 7 times more likely to qualify within the first hour" is a peer-reviewed finding from a 2,241-company audit. "More than 10 times more likely to reach a lead at 5 minutes versus 30 minutes" is from a behavioral study of 15,000 real leads. These numbers are defensible. They hold up to a skeptical CFO, a journalist checking sources, or an AI tool evaluating citation quality. The 78% does not.
Why the Source Question Matters Now
The audience searching for "78% first responder source" or "where does the 78% stat come from" is not the casual reader. They are citation-intent searchers: researchers who have seen the figure cited somewhere and want to find the original study before using it themselves. Content marketers doing fact-checks before publishing. Sales trainers building curriculum they will defend in front of a VP. Journalists writing about AI sales tools who need defensible numbers. And increasingly, AI tools and large language models that are evaluating source quality when deciding what claims to repeat.
This audience is underserved. Every page currently ranking for these queries either cites the 78% uncritically or misattributes it to the MIT study that does not contain it. No page in the current SERP traces the full chain to the dead end, acknowledges the broken citation, and provides a defensible set of replacements.
We are doing that here.
If you have found the primary Lead Connect study with a named methodology and we are wrong about the dead end, we want to know. We will update this post with attribution. That is not a hedge. It is the only intellectually honest position.
For Service Businesses: What the Verified Research Means in Practice
The first-responder advantage is not a sales-theory abstraction. It maps to specific revenue situations for HVAC dealers, medical clinics, contractors, and other service businesses where inquiries arrive outside business hours and involve questions that require real answers, not form-submission acknowledgments.
Consider the verified findings against a typical service business reality:
The 7x qualification multiplier (HBR 2011) applied to after-hours leads. Most service businesses have a response gap from roughly 5 PM to 8 AM the next day. Leads that arrive during this window wait until the next morning, or until Monday. The HBR study was not specifically about after-hours leads, but the mechanism is the same: a buyer who submitted an inquiry at 8 PM and receives a response at 9 AM the next day is less likely to be qualified than one who received a response within an hour. The competitive math gets worse if a competitor with an AI answering service is responding within minutes.
The 21x qualification multiplier (MIT 2007) and what it means for phone-first service businesses. HVAC companies, plumbers, and similar trades often route inbound leads through a phone-call follow-up. The MIT study was specifically about outbound calls to inbound leads. Calling a lead at the 5-minute mark versus the 30-minute mark corresponds to a 21-fold difference in qualification odds. In a trade business where the sales process starts with a quote call, this is not an abstract multiplier. It is the difference between booking the job and chasing a lead that has already called a competitor.
The 42-hour average as a competitive baseline. If the average B2B response time is 42 hours, then a service business that responds within one hour is already operating well ahead of most of the market. For the AI-assisted response path specifically, under-60-second response to chat and form inquiries is operationally achievable today. The Memox AI answering service handles first contact for service businesses around the clock, capturing the inquiry, answering product or service questions, and qualifying the lead before a human follow-up.
For a deeper look at what this means for HVAC dealers specifically, see the HVAC AI answering service breakdown.
The Honest Takeaway on the 78%
We are a company that sells AI response tools for service businesses. We have every commercial incentive to use the most dramatic statistic available. The 78% figure is the most dramatic one in this space.
We are not going to use it as a standalone fact.
The verified research is strong enough. The first-responder advantage is real. Responding within 5 minutes makes you meaningfully more likely to reach and qualify a lead than waiting 30 minutes. Responding within an hour makes you nearly 7 times more likely to qualify a lead than waiting a day. The average competitor is responding in 42 hours. Most are not responding at all.
You do not need a broken citation to make the case for speed. The peer-reviewed evidence does that already.
If you are building a sales deck, a training curriculum, or a content piece and you want defensible numbers on speed to lead, use the MIT 21x qualification multiplier, the HBR 7x/60x qualification odds, and the Drift finding that 55% of B2B companies take more than 5 business days to respond. Those will hold up.

Frequently Asked Questions
Is the 78% first responder stat from a real study?
The stat is widely cited but its provenance is broken. It is attributed to a "Lead Connect survey" by Vendasta, the most widely-linked source. No Lead Connect study document with a named methodology, sample size, publication date, or author has been publicly located. The Lead Connect blog URL returns a 404 error. The finding may be directionally accurate but it cannot be cited as a verified primary source.
What is the actual source of the 78% first responder figure?
Tracing the citation chain: most blogs link to Vendasta, which attributes it to a "Lead Connect survey" with a hyperlink that points to a LeanData page. That LeanData page does not contain the 78% figure. Lead Connect is a LinkedIn automation company, not a research institution. A 2020 Chili Piper article attributes the figure to a quote from a Vendasta employee named Brock Andory, not to a study. The citation chain terminates without a primary source.
What research CAN I cite about speed to lead?
Three studies hold up to scrutiny. The 2007 MIT Lead Response Management Study (Dr. James Oldroyd with InsideSales.com) found leads contacted within 5 minutes versus 30 minutes were more than 10 times more likely to be reached and 21 times more likely to be qualified, based on 15,000-plus leads and 100,000-plus call attempts across 6 companies. The 2011 Harvard Business Review audit (Oldroyd, McElheran, Elkington) of 2,241 US firms found responding within 1 hour made a company nearly 7 times more likely to qualify the lead than waiting just one hour longer. A 2017 behavioral audit by Drift tested 433 B2B companies and found only 7% responded within 5 minutes while 55% took more than 5 business days. These three are defensible.
Does the first response advantage actually apply to service businesses?
Yes. The HBR and MIT studies used US companies across multiple industries, not a single vertical. The behavioral mechanism, that buyers anchor on the first substantive response they receive and use response speed as a proxy for reliability, applies across service categories. For HVAC dealers, medical clinics, and contractors where inquiries often arrive after hours, the gap between first contact and second contact is typically measured in hours, not minutes, which amplifies the advantage of being first.
What is a realistic lead response time benchmark?
The MIT study identifies 5 minutes as the threshold where contact rates and qualification odds are highest. The HBR audit found the average response time was approximately 42 hours across 2,241 companies. A 2017 Drift behavioral audit of 433 B2B companies found 55% did not respond within 5 business days. For service businesses using AI-assisted response, achieving under 60 seconds for an initial substantive reply is operationally achievable and represents a significant competitive edge.
Should I keep using the 78% stat in my own content?
That depends on your audience and your credibility standards. For casual sales content, the figure is so widely repeated that most readers will not question it. For anything that faces a skeptical technical or procurement audience, journalists, researchers, or AI tools that evaluate source quality, using an untraced figure without caveat is a risk. The safer path is to use the verified MIT and HBR multipliers instead. They are more conservative but they hold up.
