It's a concern we raised while starting the project but the other services I mentioned also had Stripe in their names and have been operating for a few years. Because our product is so connected to Stripe we felt that it was necessary to make its purpose clear so we took the gamble and added to our content that we are not affiliated to them. If we have to change the name in the future that is something we will have to deal with when the time comes.

No you're 100% getting an email from Stripe legal TODAY. You took their name, colors, branding... It's a field day for them

That’s a pretty bold take. I bet they’re a few months out. And I don’t think it makes sense to characterize it as a “field day” for stripe’s legal department - trademark enforcement isn’t a profit center. More likely a lightly edited boilerplate letter and a timeline to comply, which GP has already acknowledged.
