Interesting project but the Estimated Monthly Recurring Revenue is kind of vague and has no explanation, so I'm not convinced the results are genuine...
A site that does this well is Indie Hackers, which was acquired by Stripe and has a [1] "Stripe Verified" option in their user-provided Products list, which seems more legit...
Thanks for this feedback! Since these projects are obviously not public companies, there is no way to get the accurate revenue numbers.
Today, all these MRR numbers are from online sources (news and founder interviews). Let me add a note for these numbers soon.
I think even "Stripe Verified" badge has its own limitation given that not everyone is using Stripe or wants to allow IndieHackers to disclose information from Stripe accounts. But yeah, I totally agree that there needs to be clarification on where these MRR numbers are from.
Some of those seem to be just online frontends to physical businesses? For example MazeEngineers and Bookblock -- sure they need online to find customers, but that's not how they make money.
