Where it sits in the data

Official IQ Test's $1K a month is higher than 40% of the 6,604 projects with founder-reported monthly revenue in our dataset; the median across them is $2K. Snapshot: 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

In my view, demand comes from people who want an online IQ assessment, a detailed report and a downloadable certificate. Buyers include individuals taking the test and businesses selecting an IQ testing service for their users or teams.

Distribution would need a content surface, search visibility and direct outreach to relevant organizations. Building the test is only part of the work: question design, scoring consistency, report generation, data handling, support and credibility all require sustained attention, alongside competition and rules around psychological testing.

Verdict: Needs real work.

One thing to take from it

A useful lesson is to package the assessment, score, detailed report, category breakdown and downloadable certificate into one product experience. Official IQ Test presents those elements together and reports 793,587 completed tests.
