A two-sided verified-review directory that's worthless until it has reviews for the school a parent is checking — the classic cold-start that kills solo review-site founders, and Google Reviews owns the default behaviour with infinite inventory. There's no revenue model: parents read reviews for free and martial-arts schools won't pay to be policed on safety. This is the classic discovery apps/marketplace tarpit: it requires massive two-sided liquidity of verified reviews in specific local geographies before it provides any utility to a searching parent.

Hand-build verified profiles for every martial-arts school in ONE city and prove 50 parents will pay (or that a school will pay for a verified badge) before the directory has national coverage. 50 parents in a single city voluntarily go through the friction of uploading their child's enrollment receipts with zero financial incentive.
Parents choosing children's extracurricular activities are making high-stakes safety decisions with garbage data. Google Reviews and Yelp have zero mechanism to verify that a reviewer's child actually attended the programme. One community post (4,721 upvotes, 509 comments) details a parent who was warned about a martial arts school, ignored the warning because the school had strong online reviews, and the school turned out to be dangerous. The post title says it all: "I was warned about my child's martial arts school. I should have listened." Meanwhile, AI-generated fake reviews are flooding…
