# Recruit participants
> Set up target groups, profiles and budget to collect responses from Exoid's global panel.
When you need qualified respondents outside your own user base, you can tap into the global panel built into Exoid: more than 5 million active participants, reachable with precise demographic and behavioral targeting criteria.
The panel opens as a screen layered over the dashboard. From there you configure the target group, watch panel availability and estimated cost in real time, and launch fieldwork with one click.
Where to find it: **Campaign → Share tab → "Hire participants"**.
## Real-time indicators
At the top of the screen you find three always-visible values that update every time you change a parameter.
How many panel respondents match the criteria you set. It shrinks every time you add or narrow a profile.
The Cost Per Interview: what you pay in euros for each completed response. It changes with country, expected incidence, interview length and how tight the applied profiles are.
CPI multiplied by the number of required completes. The system recalculates it on every change.
If **Feasibility drops to zero** the launch is blocked until you loosen the filters. Watch the cost too: a low expected incidence and long interviews push the CPI up, and with it the total cost.
## Survey criteria
This is where you set the core parameters of the target group. You can create several target groups for the same campaign, each with its own configuration.
Identifying label for the group. Default: "Target group 1".
The market to recruit participants from, chosen among 156 available countries. It determines which targeting profiles you find in the library, and it is one of the factors that move the CPI.
The language spoken by participants. Combined with the country, it defines the profiles available for that specific market and language pairing.
How many interviews you want to collect. The total cost is this number multiplied by the CPI: doubling the completes doubles the spend.
The estimated share of panel members who pass the screener and complete the interview. The lower it is, the higher the CPI: the system has to contact far more people for each usable interview.
The estimated average time to complete the interview. The longer the interview, the higher the CPI: estimate it on the respondent's actual path, not on the number of questions on the canvas.
How many days you have to collect responses. At the end of the last day the study closes on its own. It is the only required field in this section: leave it empty and the launch stays blocked.
Turn it on if your study collects personally identifiable information: name, email, address. It is a compliance flag and does not change the price.
## Profiling
In Profiling you define the characteristics of participants, picking demographic and behavioral criteria from the built-in library. Without at least one profile configured you cannot launch.
Click **Add profile**. The available profiles vary with the country and language combination you selected, and are organized into **24 thematic categories** — from Demographic and B2B/Employment to Food/Snacks, Automotive, Medical/Health and many more.
Click a profile to open its configuration screen. There you pick the options that qualify a participant (for Gender: Male, Female) and define numeric ranges (for Age: 18–34, or several combined ranges such as 18–25 and 45–54). Every criterion you add narrows the Feasibility and can push the CPI up.
After you save, the profile appears in the Profiling section as an expandable card. From there you see how many panel respondents match that criterion (profile Feasibility), edit the selected options or remove the profile.
### Quotas enabled
Every profile has a **Quotas enabled** toggle. Turn it on and the system distributes completes as percentages across the selected options: that's how you get, for example, a 50% male and 50% female sample.
## Launching the campaign
The launch unlocks once you have at least one profile configured in the Profiling section, Fielding time filled in (the only required field) and Feasibility above zero, meaning there are participants available for the criteria you set.
Past that gate, fieldwork moves outside the platform: the panel contacts participants, their answers land in your campaign like any other response, and you follow the run from the target group report.

Once the conditions are met, click **Launch** to start fieldwork. At any time you can save the configuration with **Save draft** and pick it up later.
## Monitoring recruiting
Every target group you launch comes with a detailed report. It shows campaign progress and sample quality in real time.
Country, language, target group state and creation date.
CPI, required completes and total cost.
Completes over time, average interview length, declared incidence versus actual incidence.
Summary of the applied profiles and the conditions you configured.
## Next steps
Balance your sample by limiting how many people complete it for each answer.
Recruiting consumes credits: check your workspace balance before launching.
