When you don't have the participants yourself, we recruit them. There are two routes: our **consumer panel** for audiences that exist in reasonable numbers, and **niche audience** recruiting for people the panel can't reach.

Both are available on studies where you chose **Panel** as the recruiting method in [Step 4](/creating-a-study/setup-interview#recruiting-method).

***

## Recruit from our panel

Our consumer panel is 4 million+ verified respondents across [58 countries](#where-we-recruit). You set a target, we field it, and completed interviews flow into your dashboard as they happen.

### Setting up a panel

<Steps>
  <Step title="Open Invite Participants">
    On your study dashboard, click **Invite Participants** → **Recruit from Our Panel**.
  </Step>

  <Step title="Set how many interviews you want">
    The default is 20. Minimum is 1. See [How many participants do you need?](#how-many-participants-do-you-need) if you're not sure.
  </Step>

  <Step title="Choose a frequency">
    **One-time** fields your target once. **Weekly** or **Monthly** recruits that many interviews on repeat — see [Recurring panels](#recurring-panels) below.
  </Step>

  <Step title="Choose a country">
    Participants are recruited from the country you select — see [Where we recruit](#where-we-recruit) for the full list. The interview language comes from your study settings.
  </Step>

  <Step title="Launch">
    Confirm, and the study moves to **Fielding**. Watch progress on the dashboard.
  </Step>
</Steps>

Your screener questions and targeting attributes from Step 4 are what the panel matches against, so get those right before you field.

### Where we recruit

The panel fields in **58 countries** across the Americas, Europe, Asia-Pacific, the Middle East, and Africa. You pick one country per panel — for a multi-market study, see [Running the same study in several countries](#running-the-same-study-in-several-countries).

| Region                   | Countries                                                                                                                                                                                                               |
| ------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Americas**             | United States, Canada, Mexico, Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Peru                                                                                               |
| **Europe**               | United Kingdom, Ireland, France, Germany, Spain, Portugal, Italy, Netherlands, Belgium, Luxembourg, Switzerland, Austria, Denmark, Finland, Norway, Sweden, Poland, Czechia, Slovakia, Hungary, Romania, Greece, Russia |
| **Asia-Pacific**         | Australia, New Zealand, China, Hong Kong, Taiwan, Japan, South Korea, Singapore, Malaysia, Indonesia, Philippines, Thailand, Vietnam, India, Pakistan                                                                   |
| **Middle East & Africa** | United Arab Emirates, Saudi Arabia, Egypt, Turkey, South Africa, Nigeria, Kenya, Uganda                                                                                                                                 |

A few appear in the dropdown under their official names — Korea (Republic of), Viet Nam, Bolivia (Plurinational State of), and United Kingdom of Great Britain and Northern Ireland. Type the first few letters and they'll surface.

<Note>
  **Language narrows the list.** The country picker only shows countries where your study's interview language is available, so set the language first if you have a specific market in mind. English is available in most of these countries; a language like Swedish or Thai is available in its own. If your country isn't showing, that's usually why.
</Note>

<Tip>
  Working through the API? [List Panel Countries](/api-reference/public-panel-countries/list-panel-countries) returns the current countries with the languages each supports, and takes a `language` or `country` filter.
</Tip>

### Running the same study in several countries

A study fields one panel at a time, so multi-market work is two shapes:

| You want                          | Do this                                                                                                                                                                               |
| --------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| One combined read across markets  | Field a panel in the first country, let it finish, then launch the next country on the same study. All the interviews sit in one dashboard and one report.                            |
| A per-market read you can compare | [Duplicate the study](/managing-your-study/study-actions#duplicate-study) per country and field each separately. Same questions, separate reports, clean market-by-market comparison. |

Set the interview language for each one before you field it — the language is a study setting, not a panel setting, so a study duplicated for Japan wants its language switched before launch.

### Recurring panels

Setting a frequency of **Weekly** or **Monthly** recruits your target number of interviews on that cadence, rather than once.

This is how you run a tracking study — the same questions to a fresh sample every month, so you can see a trend rather than a snapshot. Each wave lands in the same study, so the comparison is like-for-like.

<Note>
  A study can only field one panel at a time. If you set up a new panel while one is already fielding, you'll be asked to stop the existing one first.
</Note>

### What it costs

**\$30 per participant**, on top of credits for the interviews themselves. You're billed **only for interviews rated Excellent or Good** — Fair and Poor conversations cost you nothing, neither the participant fee nor the credits.

When you launch a panel, a hold is placed on your card for the participant rewards. You're charged against it as quality interviews come in, not up front. Enterprise customers are invoiced under their agreement instead.

If your credit balance won't cover the number of interviews you've asked for, you'll be prompted to top up before the panel launches.

### Quality

Panel participants are multi-layer verified before they reach your study, and every completed interview is rated the same way your own participants' interviews are — Excellent, Good, Fair, or Poor.

You pay only for **Excellent** and **Good**. That's a higher bar than we apply when you bring your own participants, where Fair is also charged — the difference being that here we chose the participant, so a thin conversation is our problem to absorb.

## Recruit a niche audience

<Info>
  **Beta.** Available from **Invite Participants** → **Recruit a Niche Audience**.
</Info>

Our standard panel covers general consumers. A niche audience is anyone that panel can't reach: specific job titles and seniority, decision-makers, low-incidence consumers such as drone owners or crypto traders, or hard-to-reach geographies.

### How it differs from the panel

**Sourced for you, not sampled.** We recruit these participants directly for your study. That means a real lead time — usually days, not hours.

**Every participant is verified.** We confirm people are who they say they are before they reach your study — role and employer, ID, or product proof, depending on who you're after.

**Priced above standard consumer.** One all-in price per completed interview, covering the participant's incentive plus the recruiting work. No setup fees, no minimums, and you're billed only on approved completes.

### What it costs

Most niche audiences land between **\$50 and \$500 per complete**.

| Audience              | Why it prices where it does                       | All-in, per complete |
| --------------------- | ------------------------------------------------- | -------------------- |
| Drone owners (US)     | Consumer, but low incidence — needs product proof | \~\$50               |
| Ad managers           | B2B role, employer verified                       | \~\$140              |
| IT decision-makers    | Seniority plus buying authority                   | \~\$185              |
| CFOs / VPs of Finance | Executive time is expensive                       | \~\$280+             |

**These are examples, not a rate card.** Your quote depends on how rare the audience is, session length, country, and how fast you need it.

### Requesting a quote

Say how many completes you want as well as who — see [How many participants do you need?](#how-many-participants-do-you-need). Beyond that, the more specific you are about who, the faster and tighter the quote. Role, seniority, company size, industry, geography, and any product or behaviour that has to be true of them.

You'll have a quote **within 24 hours**. Recruiting itself starts once you accept.

<Tip>
  Say what you'd accept as well as what you want. "VP Finance or above at 500+ employee US companies, but Director-level is fine if they own the budget" gets you a workable quote; "finance leaders" gets you a clarifying question and another day's delay.
</Tip>

## Which one do I need?

Ask how many of 100 random people would qualify for your study.

| Roughly how many qualify | Route                    | Turnaround                                     |
| ------------------------ | ------------------------ | ---------------------------------------------- |
| More than 20             | Recruit from our panel   | Usually within 24 hours                        |
| 10 to 20                 | Recruit from our panel   | Longer than 24 hours                           |
| Fewer than 10            | Recruit a niche audience | Quote in 24 hours, then a recruiting lead time |

Any B2B audience defined by job title is almost always a niche recruit, however large the companies are.

***

## How many participants do you need?

This applies whichever route you take. The number comes from how common the thing you're looking for is, and how confident you need to be that you'd have heard about it.

<SampleSizeCalculator />

The panel dialog defaults to 20. That's a reasonable starting point, not an answer.

Getting it wrong costs in both directions, and the size of that cost depends on the route:

| Route              | Per complete | What a bad estimate costs                                                                    |
| ------------------ | ------------ | -------------------------------------------------------------------------------------------- |
| **Our panel**      | \$30         | Under-fielding wastes the study; over-fielding pays for interviews that told you nothing new |
| **Niche audience** | \$50–\$500   | The same mistake, ten times the price — worth getting right before you accept a quote        |

<Note>
  Size **per segment**, not per study. If you're comparing four groups, a target of 20 gives you five interviews each — treat it as four studies of five, and size accordingly.

## Frequently Asked Questions

<AccordionGroup>
  <Accordion title="Which countries can you recruit in?">
    58, spanning the Americas, Europe, Asia-Pacific, the Middle East, and Africa — the full list is in [Where we recruit](#where-we-recruit). One country per panel, and the picker is filtered by your study's interview language.
  </Accordion>

  <Accordion title="Can I run the same study in more than one country?">
    Yes, one country at a time — a study fields one panel at a time. Run them back to back on the same study for a combined read, or duplicate the study per country for separate reports. See [Running the same study in several countries](#running-the-same-study-in-several-countries).
  </Accordion>

  <Accordion title="Can I use the panel and my own participants in the same study?">
    No — a study is either panel or bring-your-own. Run two studies if you want both; you'll get a cleaner comparison out of it.
  </Accordion>

  <Accordion title="Can I test the study myself before fielding a panel?">
    Yes. **Copy Test Link** from the Invite Participants menu gives you a link to run through it yourself. Test conversations are free.
  </Accordion>

  <Accordion title="What happens if the panel can't hit my target?">
    You're only billed for the completes you get. If an audience is proving harder to reach than expected, we'll tell you rather than let it field indefinitely.
  </Accordion>

  <Accordion title="Can I pause a fielding panel?">
    Yes — **Actions** → **Pause Study**. See [Study actions](/managing-your-study/study-actions#pause-and-resume).
  </Accordion>

  <Accordion title="Do panel participants get paid?">
    Yes, and User Intuition handles it. The \$30 is a pass-through to the participant. You don't set or send rewards on panel studies — that option only appears for your own participants.
  </Accordion>
