~$160 per paid referral: a reasoned blended value of one paid referral (published terms: $160 per acquisition (CPA); Not publicly posted (Katalys tracks with cookieless attribution) cookie). A conservative model, not a guaranteed payout.
Good to know: Katalys lists Willow at $160 CPA in its weight-loss guide (February 25, 2026) and telehealth guide (March 11, 2026) but has no page of its own for it, and says guide rates may have changed; confirm the live payout in Katalys after approval. Katalys's guides describe Willow as connecting patients with compounded GLP-1 medications, which FDA does not review for safety, effectiveness or quality.
