How a solo founder used Codex and ChatGPT to launch a fashion brand without engineers | Yana Welinder Yana Welinder, solo founder of Yana Bana, used OpenAI's Codex and ChatGPT Images 2.0 to launch an AI-native fashion brand without engineers, creating designs from hand-drawn sketches to runway photos, CAD files for 3D printing, and a Stripe-connected pre-order site. She detailed her workflow on the podcast, including using Codex with computer use to operate CLO 3D software and building the e-commerce site with Vercel, GitHub, and Stripe. Yana Welinder is the solo founder of Yana Bana, an AI-native fashion brand built with AI as her technical co-founder, starting from hand-drawn sketches and ending with runway photos, CAD files for 3D printing, and a live Stripe-connected pre-order site—no engineers required. A former product leader, she brings an operator’s rigor to her creative process: her “fashion prompt” is a detailed spec covering silhouette, volume, fabric beavior, movement, and sound, and watching her use Codex plus computer use to navigate 3D design software that’s entirely new to her is a clarifying demo of what today’s toolset actually makes possible.
