Thank you for your insightful answer. As I understand, Stripe grew so huge first via its great API (I distinctly remember comparing it against its competitors back in the early 2010s, and even though Stripe was more expensive, the developer ease was worth it) and then by being the go-to default. As you say, now other products have long caught up w.r.t. API niceness, and Stripe is simply riding momentum. Of course, Stripe has also expanded into tons of other categories. I wonder how much of their revenue comes from those other new products. If they are successfully growing those products, I still think Stripe has good fundamentals... but I don't actually know how well those products are doing and how much revenue (and revenue growth) comes from them.
