Where it sits in the data

Ace The Data Science Interview's $4K a month is higher than 56% 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 is clearest for people preparing for Data Science, Data Analyst, and machine-learning interviews. The buyer would be an individual candidate preparing for an interview, with a book as the core product and a video course as the complementary product.

Distribution would need to come through visible channels such as Amazon, email collection, interview guides, and book recommendations. The difficult part is producing accurate questions, full solutions, templates, walkthroughs, and coaching while handling the support load of interview preparation. Competition would matter in books, courses, and interview-practice platforms.

Verdict: Needs real work.

One thing to take from it

Ace The Data Science Interview pairs a 301-page book with a 25+ video-lesson course, downloadable templates, and 1:1 coaching packages. The visible sales signal is more than 50,000 books sold, while the reported monthly revenue is $4K a month, self-reported, as of 2022-09.
