Hmm, this doesn't really seem to me like the sort of area where you bring out a MVP and then work out basic fundamentals like this afterwards.
I’d argue that before Stripe sends any PII other than validation results to a customer, it needs to verify that the business indeed is under regulatory requirements to gather this data, and only sell the required part.
Alternatively, you could invert the process, allowing integrating businesses to send documents to Stripe, who replies if they’re legit or not.
Finally, if there is a need for sharing data with customers for e.g. KYC, shouldn’t this be priced significantly higher than verification/validation, so that Discords and Clubhouses can’t justify it from a business perspective?
What is the reasoning for doing neither of the above?
