CanIPay - Will Your Card Work Abroad?

If an entrepreneur "adopted" this product today, here's the realistic math.

Fermi summary

If you hit 45k monthly visitors at a $0.06 blended affiliate yield per visit, that's $32k ARR - but you're fighting entrenched SEO giants for queries that fintech apps have already claimed, so call it a 22% shot.

Go-to-market motion

SEO targeting long-tail queries ('will my Visa card work in Japan') → free tool with affiliate links to Wise/Revolut/travel cards embedded in results pages.

Key risks

Card acceptance data is inherently dynamic - bank policies, POS terminal networks, and country-level restrictions change constantly, and a single viral tweet about a wrong answer can destroy trust
Wise and Revolut already surface this info inside their apps to millions of existing users for free, making it hard to be the authoritative destination
NerdWallet, The Points Guy, and Bankrate already rank for these queries with domain authority that would take 18+ months of SEO investment to compete with
