DataExpert.io: an ex-Airbnb engineer's $4.8M bootcamp business

Q: Why did DataExpert.io work?

Credibility from real work. His posts are framed around leaving a data engineering job at Airbnb to teach (DataExpert.io newsletter). An audience before the product. TrustMRR lists 51.3k followers on X for the founder (TrustMRR listing). Cohorts scaled revenue. Wilson says 2025 had more boot camps than the two previous years combined and made more money than both years combined (Zach Wilson on LinkedIn, Feb 2026).

Q: What didn't work for DataExpert.io, and what are the risks?

Over-hiring. He writes "I over hired last year and it hurt my business" (Zach Wilson on LinkedIn, Dec 2024). By July 2024 everyone except one employee had been let go (Zach Wilson on LinkedIn, Feb 2026). Founder dependence. Three planned 2025 cohorts were cancelled while he grieved the loss of his dog, who he calls the brand's mascot (Zach Wilson on LinkedIn, Feb 2026). MRR is not the whole picture. Revenue in the last 30 days on TrustMRR was higher than MRR, which fits a business with large one-off cohort payments (TrustMRR listing). The LinkedIn revenue figures are self-reported. Only the TrustMRR numbers are payment-provider verified.
