Research

The speed-to-lead research,
read closely.

Three studies get cited in every pitch about response time — usually as a bare multiplier, rarely with a link, never with their limits. Here is what each one actually measured, what it found, and what it doesn’t say. Primary sources linked; read them yourself.

Study I · Harvard Business Review, 2011

The Short Life of Online Sales Leads

James B. Oldroyd, Kristina McElheran, David Elkington

What it didThe authors audited how quickly 2,241 U.S. companies responded to a web-generated test lead, and separately analyzed response-time outcomes across a large set of real leads.

What it foundFirms that contacted a lead within an hour were roughly seven times more likely to qualify it than firms that waited even an hour longer — and more than sixty times more likely than firms that waited a day or more. Equally striking: a large share of companies in the audit never responded at all.

Read it with these caveats

  • It measures qualification odds, not closed revenue. The famous multiplier is about reaching a decision-maker while they're still engaged, not about signed contracts.
  • The data is from 2011. Buyer expectations have compressed since, but if you quote the number, you're quoting a 2011 measurement.
  • It studied B2B web leads. Applying it to a med spa's Instagram DMs is an extrapolation — a reasonable one, but say so.

Study II · Lead Response Management Study

The Lead Response Management Study

James B. Oldroyd (research), published via InsideSales/LeadResponseManagement.org

What it didAn analysis of several years of call-log data across companies responding to web leads, measuring how contact and qualification odds decay as minutes pass.

What it foundThe odds of making contact with a lead at all drop sharply after the first five minutes. This is the origin of the 'five-minute rule' — the observation that a lead's willingness to pick up decays on the scale of minutes, not hours.

Read it with these caveats

  • It's the study behind most '21x' and '100x' claims you'll see in vendor decks — usually quoted without the qualifier that it measured contact and qualification odds on phone follow-up of web leads.
  • The dataset predates texting-first behavior. The direction of the finding has aged well; any specific multiplier should be treated as directional.
  • Speed helps you reach the lead. What you say when you reach them is a different problem the study doesn't touch.

Study III · Clio Legal Trends Report

The Legal Trends Report

Clio (annual, based on aggregated legal-practice data and surveys)

What it didClio's annual report aggregates anonymized data from tens of thousands of legal practices plus consumer surveys, including studies of how firms handle inbound inquiries.

What it foundLarge shares of law firm inquiries simply go unanswered — in Clio's mystery-shopper style studies, many firms failed to respond to email inquiries at all, and phone handling frequently failed to answer the questions asked.

Read it with these caveats

  • It's legal-industry specific. We cite it for law firms and treat it as suggestive, not proof, for adjacent premium services.
  • It's published by a practice-management vendor. The methodology is documented and the sample is enormous, but read the methods section yourself.
  • The headline isn't that response is slow — it's that response often never happens. That's an operations finding, not a marketing one.

Why we publish this

Paramount’s essays cite exactly these three sources and nothing else, because these are the ones we’ve read end to end. When a claim on this site needs a number, it comes from here, quoted with its limits. If you’re quoting the research in your own writing, link the primary source — and feel free to link this page for the caveats.

Your own numbers beat
anyone’s study.

The free audit tool applies this research to your inquiry volume and case value — your inputs, your math, nothing invented.
