Research sample providers: Trade-offs for B2B and healthcare studies

There are many sources of research sample: your own customer data, consumer exchanges, consumer panels, consumer-profiled panels, B2B and healthcare panels, verified practitioner communities, aggregators, expert networks and CATI (computer-assisted telephone interviewing) providers. For B2B and healthcare studies, the most important thing to ask any provider is how it verifies that each respondent is a real person who holds the role they claim.

What is a research sample provider?

A research sample provider is a company or source that supplies the people who take part in a survey, interview or focus group. The people supplied are called the sample, and each person who finishes a survey is called a complete. Sample providers differ in how they find respondents, how well they know who those respondents are and how much they charge for each complete.

For a consumer study, almost any adult can qualify, so the main concerns are scale and cost. For a B2B or healthcare study, the respondent has to hold a specific job, work in a specific industry or treat a specific condition. That requirement makes the provider's method of confirming identity and role a key factor in deciding if the data can be trusted.

What are the main types of research sample providers?

The table below compares nine types of sample source by what they are, what they are best for and their relative cost.

Relative cost runs from $ (lowest) to $$$$ (highest).

Customer data

Customer data is the contact information your company already holds in its CRM or customer database. Recruiting from customer data means inviting your own customers to take part in research. It is the cheapest source of sample because you pay only for incentives and the staff time to manage outreach. Customer data works well for satisfaction, churn and product feedback studies. Your customer list cannot tell you what prospects or competitors' customers think, so it does not suit market sizing or brand perception studies.

It can be challenging to get internal teams to dedicate the time to develop and send the communication necessary to recruit your existing customers. That's why Emporia will manage the outreach and incentive distribution on behalf of your company. Additionally, Emporia can hydrate your existing customer data and screen them all using our anti-fraud technology.

Consumer exchange

A consumer exchange is a marketplace where many independent panels contribute respondents into one shared network. Software routes each respondent to a survey they qualify for. Exchanges are built for consumer studies that need thousands of completes quickly. Because respondents arrive from many sources, the buyer has little visibility into how any one respondent was recruited or checked.

Consumer panel

A consumer panel is a pool of people that one company recruits, profiles and manages to take surveys. The panel company owns the relationship with its members, which gives it more control over quality than an exchange has. Consumer panels suit general population studies and are among the lowest-cost sources of sample.

Consumer-profiled panel

A consumer-profiled panel is a consumer panel that groups its members by the job titles and industries they report about themselves and then sells those members as B2B sample. These panels are large and fast. Their profiles are self-reported and rarely re-checked, so a member who says they are an IT decision-maker may have changed jobs or may never have held that role at all. Our guide to consumer-profiled vs. true B2B-profiled panels explains the difference in detail.

B2B and healthcare panel

A B2B and healthcare panel recruits professionals for business and clinical research and profiles them by role, industry and specialty. Because the panel is built for professional research, its members are more likely to hold the roles they report than members of a consumer-profiled panel. How each panel checks those roles varies, so ask the provider what evidence it uses.

Verified practitioner community

A verified practitioner community like Emporia is a first-party community of B2B and healthcare professionals whose identity and role are verified when they join and re-verified on a recurring basis. The provider recruits each member directly and owns the relationship with them. Verification checks each member's role against public data sources, such as LinkedIn profiles and NPI records for clinicians, and runs proprietary anti-fraud technology on every respondent. The checks run automatically, so a verified practitioner community can confirm thousands of professionals at a time. Verified practitioner communities cost more per complete than B2B and healthcare panels and less than expert networks.

Aggregator

An aggregator gives buyers access to many panel providers through one relationship and one contract. Aggregators help when a single panel cannot fill a niche audience or a large sample on its own. The quality of the aggregated sample depends on the panels underneath it, so ask which panels are used and whether the aggregator applies its own fraud checks to every respondent.

Expert network

An expert network is a recruiter-led firm that finds and vets hard-to-reach professionals one at a time for each project. Expert networks are the usual choice for a small volume of niche professionals. They are the most expensive source of sample because a person does the recruiting and vetting for every respondent.

CATI

In a CATI study, trained interviewers recruit and interview respondents by phone and enter the answers into survey software. CATI reaches audiences who are hard to find online, such as older adults and people in regions with low internet use. The cost of a CATI study depends on how many interviewer hours it needs.

How much do different types of sample providers cost?

Expert networks cost the most per respondent because a recruiter finds and vets each person. Verified practitioner communities are the next most expensive, because verification and fraud screening are built into how members join and take surveys. B2B and healthcare panels, aggregators and consumer-profiled panels sit in the middle of the range. Consumer panels and consumer exchanges cost the least of the outside providers.

Customer data has the lowest outside cost, since you pay only incentives and the internal time to run outreach. CATI pricing follows interviewer hours, so it varies widely with the audience and the length of the survey.

A low price per complete stops being a saving once you remove the completes that fail quality checks. When you compare quotes for a B2B study, compare the cost of each usable complete after cleaning.

How should you evaluate a sample provider for B2B and healthcare research?

Use the six questions below to compare providers for any study that needs professional or clinical respondents.

1. How does the provider recruit its respondents?

Ask whether the provider recruits its respondents directly or sources them from partner panels. A provider that recruits its own members holds the relationship with them and can remove a member who gives poor data. If the provider blends with partner sample, ask what share of your study will come from partners.

2. How does the provider verify identity and role, and how often?

A B2B respondent should be checked against evidence outside their own profile, such as a work email domain or a LinkedIn profile. A healthcare provider respondent should be checked against their NPI record. Ask whether these checks happen once at sign-up or again before each study, since people change jobs and profiles go out of date.

3. How does the provider screen for fraud before, during and after the survey?

Fraud screening before the survey keeps fake and unqualified respondents out of your data. Checks during the survey catch bots and inattentive respondents as they answer. Cleaning after the survey removes what got through. Ask the provider to describe the checks it runs at each of these three stages.

4. Can the provider reach your audience at the size you need?

Ask for a feasibility estimate for your exact audience definition before you sign. If the provider cannot fill the study from its own respondents, ask how it will find the rest and whether those extra respondents pass the same verification.

5. Are the incentives right for the audience?

Senior professionals and physicians will not take a survey for a token reward. Incentives that are too low for the audience likely attract people who are pretending to qualify. Ask what each respondent is paid and whether that amount fits the seniority of your audience.

6. What happens when a complete is removed for poor quality?

Ask whether the provider replaces removed completes at no cost and how long replacement takes. A provider that stands behind its sample will have a clear answer.

How common is fraud in B2B survey sample?

Fraud and low-quality responses are common in B2B survey sample. The Insights Association's H1 2026 Global Data Quality Benchmarking report measured removals across about 1.8 million survey records from 46 companies in 13 countries, collected between October 2025 and March 2026. In general B2B studies, researchers removed 59.6% of qualified completes during post-survey cleaning for inattention or poor quality. The same figure for general consumer studies was 13.1%.

B2B studies attract more fraud because they pay higher incentives. A person who claims to be a chief information officer can earn more per survey than a person who claims to be a grocery shopper, and a screener question about job title is easy to answer falsely.

Post-survey cleaning catches some fraud, but it adds time after fieldwork and it cannot catch a fraudster who gives tidy, believable answers. Verifying each respondent before they enter the survey is the more reliable defense.

What should you ask a sample provider about fraud screening and expert verification?

Ask every provider the questions below, and ask whether each check applies to every respondent in your study, including respondents sourced from partner panels.

Questions about professional identity

• Do you confirm that each respondent's work email belongs to an established company?
• Do you check each respondent's job title and employer against their live LinkedIn profile?
• Do you match respondents against a database of past and flagged identities?
• For healthcare studies, do you confirm each clinician's NPI number?

Questions about devices and networks

• Do you detect multiple accounts created from the same device?
• Do you flag respondents who connect through a VPN, proxy or Tor?
• Do you screen for synthetic identities and AI-generated profiles?

Questions about response quality

• Do you review open-ended answers for gibberish, bot-written text and low-effort replies?
• Do you monitor for speeding, straight-lining and answers that contradict each other?
• Does a person with sampling expertise review hard cases before a respondent is accepted or removed?

How does Emporia Research source B2B and healthcare respondents?

Emporia Research runs a verified practitioner community of B2B and healthcare professionals who are verified when they join and re-verified on a recurring basis. Every member is a first-party respondent, which means Emporia recruits them directly and holds the relationship with them. Emporia's B2B audiences span more than 140 industries.

For niche audiences and high-volume studies, Emporia can also use aggregation to reach more respondents through Levada, its proprietary platform for sourcing fraud-screened sample from vetted third parties. Combining first-party respondents with that network raises feasibility, extends geographic coverage and reaches audiences that one panel cannot fill alone.

Every third-party respondent passes through Emporia's anti-fraud technology before they can take a survey. That technology covers each check in the list above, from work email and LinkedIn validation to device fingerprinting, VPN and proxy detection, synthetic identity detection and human review. Buyers get the reach of a blended sample with one quality standard applied to every respondent.

Frequently asked questions

What is the difference between a sample provider and a panel provider?

A sample provider is any source that supplies research respondents. A panel provider is one type of sample provider that recruits and manages its own pool of respondents. Exchanges, aggregators, expert networks, CATI firms and your own customer data are other types of sample providers.

What is the difference between a consumer exchange and an aggregator?

A consumer exchange is an automated marketplace that routes respondents from many panels into surveys. An aggregator is a single company that manages access to many panels for a buyer through one relationship. Both draw on multiple panels, and in both cases quality depends on the checks applied to each respondent.

What is the most expensive type of research sample?

Expert networks are the most expensive type of research sample because a recruiter finds and vets each respondent by hand. Verified practitioner communities, which build verification and fraud screening into how members join and take surveys, are the next most expensive.

What is a verified practitioner community?

A verified practitioner community is a first-party community of B2B and healthcare professionals whose identity and role are verified when they join and re-verified on a recurring basis. Roles are checked against public data sources, such as LinkedIn and NPI records, and proprietary anti-fraud technology screens every respondent automatically.

Can you use a consumer panel for B2B research?

You can use a consumer-profiled panel for broad business audiences, but its job titles are self-reported and rarely updated. For studies that need decision-makers, specialists or clinicians, use a provider that verifies each respondent's role against outside evidence.

How do you know if B2B survey respondents are real?

You know B2B survey respondents are real when the provider has checked each one against evidence outside their own profile. That evidence includes a work email at an established company, a matching LinkedIn profile and, for clinicians, an NPI record. Device, network and response quality checks then catch fraud that identity checks miss.

What percentage of B2B survey responses are removed for poor quality?

In the Insights Association's H1 2026 Global Data Quality Benchmarking report, researchers removed 59.6% of qualified completes from general B2B studies during post-survey cleaning. The same figure for general consumer studies was 13.1%.
