How Yazi recruits

From opt-in to study-fit in four steps.

Every participant is recruited, profiled and consented on WhatsApp - the channel they already use every day. No app downloads. No identity gymnastics.

Opt-in

Participants opt into Yazi's network via partner brands, public campaigns and referrals - always WhatsApp-first.

Profile

Verified demographics - age, language, location, LSM/SEC - captured the same way every study runs: on chat.

Activation

Active participation, attention checks, response quality and platform reliability scoring keep the panel clean.

Study-fit invitation

When a study fits a participant's profile, they get a personal WhatsApp invite - Opt-out is one tap.
