The customers were disappearing halfway through. A San Francisco financial-services company had built APIs that connected its customers to other financial platforms. People began integrations, then abandoned them. Some APIs attracted heavy use; others languished. The company could see the departure. Explaining it was another matter.
- Zintro recruits people with specific experience, including outside its own network.
- Its teams handle screening, scheduling, compliance checks, and participant payment.
- Clients buy research recruitment by the project, without a mandatory subscription.
According to Zintro’s published case, the company needed engineers who spent at least half their time on API and Open Banking work. Zintro presented 39 qualifying profiles; the client interviewed 18 over seven business days. The findings were wonderfully unglamorous: confusing documentation and a third-party security system blocking implementation steps. A bug suppressed the error message. Engineers gave up and went elsewhere.
There is a useful distinction here. Knowing that someone left is different from knowing what happened just before they left. The second kind of knowledge often belongs to a person whose name is absent from your dashboard.
The error message that never arrived
Zintro occupies that gap. It connects organizations with specialized research participants: people who have bought a particular service, evaluated a vendor, worked in an industry, or performed a narrowly defined task. The outcome might be an expert call, a survey, a focus group, or feedback delivered over several days.
The temptation is to describe an expert network as a collection of impressive résumés. But a résumé can be impressive and useless for your question. A bank executive and an engineer debugging an integration may inhabit the same industry while knowing quite different things. For this client, the daily work mattered more than the grandeur of the title.
A database is only the guest list
Zintro says its network contains more than a million experts and professionals. It also makes a disarmingly sensible admission: “No network or panel has everyone.” Its recruitment analysts therefore search beyond the existing membership. The database is where the hunt can begin; it need not determine where it ends.
That distinction matters when several conditions must overlap. Someone may understand cloud storage but never have selected a provider. A buyer may have selected one, but too long ago to answer questions about the current market. A recruiting brief has to turn these distinctions into criteria before an interview becomes an expensive conversation with the wrong person.
The operational work is considerable. Zintro offers recruiting, screening, compliance checks, scheduling, transcription, and payment. For asynchronous studies, it also tracks participation so that a respondent who enthusiastically starts a diary does not quietly vanish from it. Recruitment extends into the less glamorous territory of getting the work completed.

The founding complaint was economic. Zintro’s investor brochure traces the company’s 2007 origin to its founder’s time as an entrepreneur-in-residence at Battery Ventures, using established expert networks and looking for a more flexible, less costly approach. Founder Stuart Lewtan’s company now lists Tyler Lewtan as CEO, alongside leaders responsible for recruitment, project management, technology, and expert care.
The price of getting into the room
Zintro’s proposition is project-based buying: no mandatory subscription, no cost or credit minimums, and no exclusivity requirement. The company says clients disliked complicated credits and high annual minimums. Its answer was to let them pay for what they use. That suits a team whose questions arrive unevenly, rather than neatly on a subscription calendar.
Pricing is quoted for the project. A research manager can request a defined audience and scope without committing to a year of calls. The practical comparison is the complete recruiting task: how many usable participants, how much screening, what scheduling support, and which deliverables the agreed fee covers.
Its customers include research agencies, consultants, investors, and corporate teams. Zintro bridges the expert-call market associated with GLG and Guidepoint and the participant-recruitment work required by market researchers. Buyers can investigate a market, test positioning, examine product friction, or ask why a purchasing decision went against them. The service supplies access; the research team still has to make sense of what people say.
A country changes. The group still meets.
One consulting engagement illustrates the coordination problem. The client wanted senior marketing leaders from sizeable US consumer businesses for focus groups. Zintro searched its network, then recruited externally. After the first group, the consultants added Canada with two days before the next session.
Zintro reports presenting 58 qualifying candidates over eight recruiting days and filling four groups, with 23 participants in total. Some candidates became ineligible and needed replacing. The telling detail is the changing brief. A research project can be perfectly planned and still acquire a new country on Tuesday.
“People are trying to move a lot faster”Tyler Lewtan, speaking to QRCA VIEWS in 2025
Readers can borrow the discipline without borrowing the vendor. Define experience through actions: bought, evaluated, implemented, rejected. Set a relevant time window. Review the candidates’ screening answers. Build room for replacements. The eloquent person who knows the industry in general may be less valuable than the awkward person who encountered your exact problem last month.
The robot still needs a respondent
The recruitment problem is changing. QRCA reported in July 2025 that fraud concerns were prompting Zintro to shift toward outreach-only recruiting. Its survey offering now emphasizes verifiable professionals with previous qualitative-study experience. When incentives attract convincing impostors, another completed response is not automatically another useful response.
Meanwhile, Zintro has recruited for agencies using third-party AI moderators, including Listen Labs and Outset. In a published exit survey of 50 participants, 82% preferred the AI experience, while respondents also reported bugs and repetitive prompts. It is a small feedback exercise, not evidence that robots conduct better research. Convenient scheduling may be doing some of the persuasive work.
The limits are straightforward. A handful of specialists cannot establish how common a view is across an entire market. Recruiting cannot rescue a leading question. And professional experience is no licence to disclose confidential information: Zintro’s rules require experts to respect their obligations. The strongest use is a precise question addressed to people qualified to answer it. Sometimes the answer is a market insight. Sometimes it is an error message that should have appeared.
