This looks cool. Please get a great product marketing manager. It took me 5-6 mins to understand what it is. I'm not a PMM, but for example this could have made things much clearer from the get go:

> We create an anonymous account around any visitor to your website

Doesn't this single sentence sum it up? Anyone who would think about buying an auth service is going to understand the implications of this. I get that you want to pitch why anyone would care, ie the value prop:

> We make it easy for developers to sign up users through a code snippet that adds account creation and authentication to any website or web app—like Stripe for accounts.

But the auth space is filled with... mostly bs products. If you pitch the value prop first, at least in auth, people will roll their eyes won't they? And the Stripe analogy isn't that great. Your value prop is that you make it easy for your customer's end users. Stripe's core value prop to customers is they make it easy for you. Both are valid, but you are sort of conflating things with the analogy.
