Frequently asked questions

Why do rewards vary?

Different studies have different recruitment needs, so referral rewards are aligned with the study category.

How will I know which reward applies?

We'll confirm the applicable referral reward once your referral has been matched to an eligible study.

When are referral rewards paid?

Referral rewards are paid once the referred participant has successfully enrolled in an eligible study.
