Their landing pages are just so beautiful, like fine art. I do wonder though the return on investment. The pages must take forever to create. Perhaps Stripe just has that much cash.
Much of what they do supports that overall strategy, from making attractive things for developers to some of the high-profile hires and acquisitions they've been making recently. Apparently the strategy is a good one, because here we all are talking about them on a site full of entrepreneurial types, and today it's not because of the service they provide but just because of their landing pages. :-)
Paypal is far bigger Stripe, so it's not that.
