Real-revenue cases

I Make $7M Per Year Shaving Men s Hairy Backs

Real demand

A husband-and-wife team built a long-handled back shaver for men who can't reach their own back hair, and used one viral comedy video to put the brand on the map; the business now runs at roughly $650K in monthly revenue.

Real-demand verdict

Real-demand verdict

Real demand

It replaces asking a partner to shave your back or paying for painful, pricey laser and waxing appointments; doing it at home in minutes is why people keep coming back for blades.

How it makes money

Customers buy the shaver directly on the brand's Shopify store, then keep reordering blade refill packs, shower soap and travel cases.

What old behavior it replaces

Having a partner shave your back, or booking laser hair removal / waxing appointments

02

Where the first customers came from

The 2016 Kickstarter and Indiegogo campaigns, amplified by Business Insider sharing the campaign video

Tactics you can copy

  1. 01Make a self-deprecating comedy video (back hair blown up into an 800lb gorilla in marriage counseling) and pitch big pages to share it, trading content for free reach
  2. 02Turn the shaver into a razor-and-blades model: the device acquires the customer, refill blades and soap keep them paying
  3. 03Collect reviews through Yotpo and iterate the product on real feedback instead of guessing
Moving it to an AI business

Not an AI business itself, but the playbook — one cheap piece of content that earns millions of free impressions, plus recurring consumables — maps directly onto AI tools: acquire with a self-spreading demo, monetize with subscription or usage.

Evidence and limits

Self-reported numbers are unaudited — treat them as leads, not facts

What evidence is missing

$650K/month is founder self-reported and unaudited; no cost, margin or refund data
No CAC, repeat-purchase rate or churn figures after the viral video
No breakdown of how much revenue comes from refill blades, so the recurring-revenue claim is unverified
