Revenue basis · Founder self-reported, unaudited (see source page)
Revenue is founder self-reported and unaudited; the page shows both $100K/month and $83K/month, so the figure is inconsistent
No breakdown of revenue by ads, sponsorships, affiliates, or courses, so the main engine is unclear
No audience size, traffic, or conversion data to validate acquisition efficiency
