Real-revenue cases
Tyson Walters built a onesie that traps dog hair and dander after his shedding St. Bernard ruined his car and house; launched October 2016, it grew on Facebook ads plus one viral media hit, reaching 30,000+ units and $1.7M in cumulative sales.

It replaces car seat covers, couch covers and the medical cone — the founder tried dozens of anti-shedding products with no luck, and covers kept tangling his dog. People keep paying because shedding and post-surgery licking are recurring, concrete problems, not one-off curiosity.
Pet owners buy the onesie per unit on the brand's Shopify site and on Amazon; the Amazon storefront is run by a third-party agency while the founder keeps pricing control.

Early traction came from small Facebook ad spend; The Dodo spotted an ad, made a video that went viral, and overnight brought hundreds of orders plus national and international media inquiries.

This is not an AI business, but its cold-start path transfers: test demand with tiny ad budgets, then ride one viral hit from a niche media outlet. For an AI app, the same sequence works — validate willingness to pay with small spend, then chase a single high-leverage community or media moment.

Revenue basis · Founder self-reported, unaudited (see source page)
The title says $70K/month while the page data says $83.3K/month; the two figures conflict and both are founder self-reported and unaudited.
No CAC, repeat-purchase rate, return rate or gross margin is given, so unit economics can't be assessed.
No evidence on whether revenue held up after the viral spike, and no data past 2019.
