Quick Answer
Unsupported business model change usually means the account now behaves like a materially different business than the one Stripe originally underwrote.
What This Signal Usually Means
The problem is often not that growth happened. The problem is that the new product, traffic source, settlement pattern, or merchant role changes the risk category enough that the old trust model no longer fits.
What Stripe Is Likely Comparing
- original onboarding model vs current offers
- historical customer-outcome profile vs the new one
- old MCC or category assumptions vs current product behavior
Most Common Root Causes
- moving from direct sales to marketplace or aggregation flows
- adding prepaid, delayed-fulfillment, or restricted products
- switching to a higher-risk acquisition or pricing model
Evidence Stripe Will Weight Most
- a precise explanation of the new model
- product and policy pages that match that explanation
- proof that controls fit the new risk surface
Operational Fix Sequence
- Describe the old model and new model side by side.
- Identify what changed in liability, category, or customer outcomes.
- Do not ask Stripe to treat the new model as if nothing changed.
