How it started
Kyan, a 21-year-old college student who had never built anything, wanted a resume project and noticed ChatGPT gave inaccurate guitar tone advice, a pain point echoed by guitarists on Reddit and Instagram. He vibe-coded V1 in about a week over Thanksgiving break, launching first as a website and later a native Swift app. Posting short-form content about three times a day and scaling winners grew it to 100K+ users and $25K/month in under five months.
