How we list founders

Only sourced revenue, never estimates

A founder is listed when a public, linkable source shows at least $500 a month in MRR (or the ARR equivalent) for a live product. Every figure shows its source, the date it was reported and what kind of source it is:

Verified by payment provider via TrustMRR: TrustMRR reads the figure from the payment provider (such as Stripe) rather than taking the founder's word.
Self-reported by the founder: The founder's own post or X bio. Nobody has checked it against their payments.
Other public source: An article, interview or another account's post.
