Looks like the page was freshly edited to remove the pricing information (?), but it's telling they're targeting a very similar price range as Veriff [0], a startup that's been working in the same space for quite a while.
This is a small localization bug that we’re fixing now (the pricing section doesn’t properly show for countries where Identity isn’t available in yet), but you can see pricing for the US at https://stripe.com/en-us/identity#pricing.
