# Stan founder builds Stanley AI tool in 14 days > Source: > Published: 2026-07-08 09:37:13+00:00 Business Insider reported July 8, 2026, that Stan cofounder **John Hu** and a cofounder built **Stanley**, an AI content assistant for creators, in **14 days**. The report says the LinkedIn version launched in June 2025, reached $200,000 in annual recurring revenue within six weeks, and later passed $1 million ARR, while both Stanley versions contributed $3 million ARR to Stan. For practitioners, the important lesson is that AI-assisted prototyping can validate narrow workflows quickly, but production teams still need data hygiene, evaluation, and maintainable systems once revenue depends on the feature.
