"What actually differentiates stripe from the rest of the bunch though? It’s the little things.Stripe obsesses over creating a seamless CX. Small annoyances in applications compound. A user might not churn immediately because you have a bunch of unoptimized functionality or crappy UX, but it’s a recipe to create a grumpy user. And grumpy users aren’t loyal users."
This is an idea I've been turning over in my head a bunch recently: the compounding effects of delighting your users. That cumulative innovation that comes from building for your customers....I sometimes get asked "what's the killer idea behind [company X]". But there isn't one big thing. There are many, many small things built on having a relentlessly customer-back attitude. You can't just copy the "idea", you have to copy the way of working and thinking. That's a lot harder.
Let's take Brex as another example. It's the segmentation, UX, marketing, rewards, underwriting, etc. It's each of those things broken up into a hundred subcomponents and iterated on. It's an entire ethos and operating model. That's cumulative innovation...not a single idea.
