Closer-to-the metal integrations with providers is definitely a big headache. Solving that problem takes a bit longer because you need bank partnerships, in many cases have to pass compliance screens, etc. We're aiming to tackle the more tractable part first which is the developer experience
If you're trying to be like Vercel—it's a red flag for any reasonable person when you clearly spent more effort on your landing page than your actual product. What made Stripe so successful is that, I personally would not even attempt, like you said, "integrations with providers" "bank partnerships" "compliance screens" because that sounds basically impossible.
I'm not saying they shouldn't be doing that. It's actually the opposite—they got the VC money, they might as well do something actually useful with it.
That's definitely the gameplan. We believe very sincerely that developers deserve more choice when it comes to payments than they currently have. It's a central reason why we started building this.
It just takes longer to make progress on that problem because of all the institutions involved.
