There are many financial services companies which are supportable. For example, Clearbanc, a financial services company, uses multiple Stripe products. We try to help users by offloading some of the regulatory and compliance work to us, but as you are aware regulation in financial services is complicated and nuanced. I can’t speculate on each possible use case serially, but we’re interested in hearing specifics and trying to support more legitimate fintech businesses versus less with this product.
As for handling exceptions on individual transactions: this is something which Stripe does very frequently with respect to our Stripe Connect users. For example, we might need to inquire about a large payment made over a Stripe Connect platform, particularly if it appears out-of-character for their usage or for that platform. (We might have questions about a million dollar “pizza” order.) Depending on our specific business relationship with the platform, the flow might be the platform reaching out to the customer for documentation, it might be the platform reviewing information provided contemporaneously with the transaction, it might involve us reviewing metadata on the transaction, or it might involve us reaching out to the user.
Depending on the specifics of what a platform does, it might have internal compliance or fraud teams. Many of our large platforms do; we interface with them (and create interfaces for them) to maximize their effectiveness and minimize silliness.
