The problem

A founder spent four months building a creator-tipping platform, and the processor closed the account a week before launch, labelling it a restricted category without saying what to change. The information existed all along, scattered across prohibited-business lists, connected-accounts terms and forum threads. Nobody reads those before writing code, and none of them answers the real question: given who pays whom, for what, in which countries, will this survive review? The cost is months of work plus a launch date.

Why now

More products are built by one person in weeks with AI assistance, so the cheapest part of a startup is now the code and the most expensive surprise is a policy decision made by a third party. Creator, marketplace and wallet models keep multiplying, and they are precisely the ones that trip restricted-category rules. The check belongs on day one, and it is a one-page job.

What it is

A short form: who pays whom, what for, whether you hold funds, content type, countries. It returns clear, ask first, or likely closed for each of four processor archetypes, with the reason for each, plus a drafted email asking the provider for written confirmation. The demo runs a scripted rule table in the browser over a snapshot dated 2026-10-04. It makes no live lookups and uses no model. It does not name real providers, submit anything, or cover individual country rules.

Who it's for

Pre-launch founders choosing a processor and early teams about to add payouts, wallets or user content. It is not for companies already in a compliance relationship with a processor, who have an account manager to ask. It is not a substitute for a lawyer on regulated products such as lending or money transmission, and it does not help anyone looking for ways to slip past review. The email exists to get an answer on the record.

How it makes money

Not yet, and that is correct for now. The value rests on a rules table that goes stale, so charging before there is a curation process would sell guesses. The first step is free with a visible snapshot date. Later, a paid tier could cover alerts when a tracked rule changes and saved reports for investors. We reject a processor referral fee: it would bias the verdicts toward whoever pays.

Go to market

Post the creator-tipping story and the pre-flight in the communities where such closures are retold: r/SaaS, Indie Hackers and Stripe-alternative threads. People who have just been closed forward it unprompted. Seed it with a handful of worked examples (tipping, wallet, marketplace) that each become a searchable page. Success is measured by how many founders send the generated email and share the reply, which also supplies the corrections that keep the table honest.
