Recruiting participants
Two ways to get people into your study:Our panels
Humanize gives you access to over 5 million participants across both B2C and B2B audiences. Set your target, specify how many people you need, and launch. Participants are sourced, screened, and scheduled automatically. B2C — general population recruitment is fully self-serve. Launch directly from Humanize. B2B — need decision-makers, developers, healthcare workers, or other professional audiences? Email us and we’ll set up a recruitment plan for you.Bring your own
Have your own list? Copy your study’s unique participant link from the Recruitment tab and share it via email, Slack, wherever. Participants click the link, fill out your screener, pass quality checks, and get scheduled.Panel participants still go through your screener. The panel provides the initial pool; your screener narrows it down.
Recruiting in rounds
You can recruit in batches. Start with a small pilot round (3–5 participants) to test your screener and guide before going full scale. Add more rounds as you need them.Scheduling
When you launch a round, you pick the session date and time — slots run in 15-minute increments from 6:00 AM to 11:45 PM (EST). The launch dialog shows the credit cost and your remaining balance before you confirm.Controlling the mix
Quotas let you recruit specific proportions — half iPhone users and half Android, say — instead of just whoever qualifies first. More on segments and quotas.Participant quality checks
Before anyone joins a session, Humanize runs automated checks to make sure you get high-quality participants who are paying attention:- AI attention checks — verifies participants are engaged and responding thoughtfully, not rushing through
- Lighting check — makes sure their face is clearly visible on camera
- Network check — confirms their internet connection is stable enough for video
- Audio and video check — camera working, mic picking up clear audio
