I don't know the ecosystem, but seemingly Stripe themselves lists some projects/products/organizations that themselves have "Stripe" in their name, as part of the "Stripe Partner Ecosystem": https://stripe.partners/?search=stripe&sort=relevance

Still, risky to use someone else's trademark regardless, if they suddenly don't like you anymore they'll start to enforce it at the worst moment.

We went with it because the other services I mentioned also had Stripe in their names and have been operating for a few years. At the moment our product is so connected to Stripe that we felt having Stripe in the name was necessary to make its purpose clear. We 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.

Was wondering about this as well. Might fly under the radar for a while but if your project grows you might draw attention from Stripe and having to rebrand later on will become difficult.

Also, what if you want to support this type of migration for other payment processors in the future? This name ties to just Stripe.

Also, tiny grammatical nitpick: the subheading should use the word seamlessly, not seamless there I think.
