About this tool

Most startup idea lists quote a revenue figure and stop there. You never learn whether the number came from a dashboard someone could check, or from a founder describing their own business on a podcast. ProvenStartups indexes 406 businesses that already make money and labels every figure with where it came from: 57 third-party verified, 184 founder-reported, 121 creator-relayed, 44 unproven. Roughly one in seven revenue claims in this space can actually be checked by someone other than the person making it. We also keep 38 documented failures. Free to read.
