It's not the magical MRR. It's different than we report ourselves on https://simpleanalytics.com/open but we still want to show it. Why? It's because Simple Analytics is build on trust and being open. The stats we show on our page could be made up (it obviously isn't), but with Indie Hackers we have a third party that has (only read-only) access to our revenue. We can't modify those numbers, so that's why we added live Stripe revenue to our profile.
Hurray for transparency!
