Stripe is a fully featured product and platform now with so many customers: it's the go-to payment provider for pretty much every startup. Do they really need this money? If so, that's scary. I want my payment provider to have a rock solid business model, not still burning VC cash.

I would expect that at this stage Stripe ought to be pulling away from VC money, as their profits hopefully increase. There are, of course, valid reasons to take VC money at a late stage - fuelling expansion is the main reason. But does Stripe really need the money to expand? I would hope that they could support their expansion themselves.

Normally I wouldn't care much, such as when Uber raised a bunch of money recently, but Stripe is different because they're so central to my business. I really need them to be rock solid. It would be a huge pain if I had to switch payment providers, especially with all of the subscription logic that Stripe provides.
