Real-revenue cases
A Utah-based online training and test-prep business selling certification courses and coaching to aspiring construction inspectors, both direct-to-consumer and to companies, self-reported at roughly $125K/month.
01
It replaces offline prep classes and self-study for a certification that is a hard gate to employment, so buyers have a concrete reason to pay; the founder reports revenue nearly doubling in two years, suggesting repeat demand and word of mouth.
Individuals preparing for construction inspector certifications buy courses directly, and companies buy training in bulk; revenue comes from course sales plus personal coaching, delivered online.
Offline prep classes and self-study
02
The source does not specify the first customers; it only says early growth came largely from word of mouth plus a small amount of SEO.
03
The transferable part is picking a narrow field with a hard certification or compliance gate, pulling search traffic with free content pages, then converting with a free trial course; an AI product can copy this in verticals where people must learn something to keep their job.
04
Revenue basis · Founder self-reported, unaudited (see source page)
Revenue is founder self-reported and unaudited; the page shows both $125K/month and 'close to $100K/mo', so the figures are inconsistent
No paying-user count, price point, repeat-purchase rate, or churn data, so revenue quality can't be judged
First-customer source and early acquisition details are missing, summarized only as 'word of mouth'
