Apple's marketing team is similar. They're probably a bunch of people who _love_ making videos; probably studied film or art or spent a ton of time on Final Cut Pro etc etc.
Where Stripe absolutely nailed it is the infrastructure around it. Their SDK documentation and continous improvements still outpace Braintree.
For instance, Stripe has custom elements that you can use to interact seamlessly with their SDK, with little setup needed[0]
I could not find a similiar integration from Braintree.
Compartively, I find their informational SDK page a bit more polished than Braintree, respectively, though I realize some of this is personal style and taste, Stripe has clear pathways for me to find the information I want right on the side bar and referenced throughout the landing page for the client SDK[1] where as Braintree[2] is more narrowly focused, which with payments, may mean I miss a better set of features I should be aware of.
Reducing frictions and painpoints is what they won with, in the end. It was easy to setup and maintain. How many 3rd party services have both of those things that handle something as complex as payments? I can't even get AWS integrations with their own SDKs working together without some effort

Although I personally feel it may just be innate appreciation or love of the craft. It's interesting to compare Stripe with other providers such as PayPal, AWS/Amazon, Square. AWS is (and has been) focussed on selling to developers, startups to massive companies. Yet, their product pages aren't as slick as Stripe's. They built out their product with the ethos from the Retail side -- frugality, ship fast & often etc. ¯\_(ツ)_/¯
Stripe got my business years ago because of the API (compared to the CyberSource merchant API at the time) and the competitive rates.
The pretty UI on their site had precisely zero bearing on the decision.
But I feel there's something to be said or appreciated about building or striving to build something beautiful despite that.
But it's essentially been 13 years (if you only start counting from the introduction of the iPhone). Great engineering/product deserves a big marketing budget. They go hand in hand.
You can tell Apple's target demographic isn't enterprise markets at every turn.
