Real-demand verdict
English teachers (and some learners) pay for physical card and dice sets, ordered through a Shopify store and Amazon FBA; an online course was added in 2019 to supplement cash flow.

Where the first customers came from
Tested with fellow teaching peers and trialed in a few local schools with permission

Tactics you can copy
- 01Pilot the product free with peers and local classrooms to get real usage feedback before mass production
- 02Get quotes from at least 5 Alibaba suppliers and ask for multiple MOQs (300/500/1,000) so suppliers think bigger orders are coming
- 03Prototype with a small US shop, mass-produce in China, but switch cards back to a US printer when paper quality and shipping costs fail
Moving it to an AI business
The playbook of piloting with teaching peers, then contract-manufacturing and selling through both a DTC store and Amazon, transfers to AI education tools: validate free with teachers or small institutions before building a paid version.

What evidence is missing
Revenue is founder self-reported at $600-$1,000/month, unaudited, and the page elsewhere lists $1,500/month — the two figures conflict
No CAC, conversion rate, or repeat-purchase data, so growth sustainability is unclear
No revenue figures for the course business, so the cash-flow structure is unknown
