Overall, places they obviously excel at are design, social proof, using straightforward copy, linking out to all the right pages and places a visitor would want to explore after the homepage, and highlighting their primary value propositions. A few critiques: much of the copy is pretty generic and lifeless, alternatives and specific competitive advantages could be exposed more, and it's actually a bit brief considering all that they do. All that considered, they really can do no wrong at their size and renown. The design and highlights pointed out here serve as good examples, but in general, it's not a good page to emulate because 99% of companies can't leverage their brand like Stripe can.
