BuiltWith
👤 Gary Brewer (Sydney dev; built it nights/weekends about 4 yrs, stayed essentially solo, refused to hire until $100k/mo. Co-founder Rogers advises.)🌐 siteLinkedIn
A solo Australian dev turned a weekend curiosity — "what is this site built with?" — into a web-scale data monopoly.
Will it work? · our read
A compounding flywheel. Be honest — tech detection isn't defensible; the head start and free-SEO distribution are. This win is timing (since 2007) plus relentless solo discipline, not one clever trick.

Crawl-scale and pricing figures are first-party; the revenue tile is a flagged third-party estimate. BuiltWith.com (crawl scale, first-party)
Widely repeated at about $14M/yr (origin: a Nathan Barry tweet, echoed by dozens of blogs). Latka estimates $22.6M for 2024. The only first-party figure ever disclosed was about $40k/month circa 2011, via co-founder Andrew Rogers. Treat current revenue as an estimate.

Revenue is NOT first-party: the famous $14M/yr traces to a Nathan Barry tweet echoed by blogs, and Latka estimates $22.6M (2024) — both flagged estimates. The only first-party revenue ever stated was about $40k/mo (circa 2011) by co-founder Andrew Rogers. Headcount claims range from 1 to about 9; treated as "essentially solo." Pricing, crawl-scale and technology-count figures ARE first-party from builtwith.com. Revenue flagged EST; not independently confirmed. We never score you.
