The submission presents significant discrepancies between claims and verifiable data. While described as a personal consulting portfolio, it lists a team of 6 and claims 'everyone' as the audience. The statement 'most people have used my product' is hyperbolic and unsupported by the provided URL, which currently lacks a significant search engine footprint. Financial metrics are ambiguous ('marketcap' used for revenue) and low for a 17-year operational history. The project scores highly on skepticism due to these inconsistencies.
