Who holds the money when affiliates get paid?
Here is the part that is the same, and it matters.
Refgrow's docs say "nothing leaves your account without your approval" in manual mode, and in automatic mode Refgrow "instantly processes the payment through your configured provider", PayPal first, then Wise. Its terms say payouts are processed through PayPal or Wise, and that Refgrow is not responsible for delays at either. So the money goes from your PayPal or Wise to your affiliate. Refgrow never holds it, and there is no cut.
AffiliateRail works the same way. It works out who is owed what, then logs into your own PayPal or Wise on a schedule and pays them. The money leaves your account and lands in theirs. The difference is when: Refgrow pays when an affiliate asks. We pay when it is due.
