In this solo walkthrough, Stefan Georgi demonstrates his agentic marketing platform, Stefan Brain, by taking a real ad for the Vumi supplement and constructing an entire marketing funnel in under 20 minutes. He starts by importing the ad via GetHooked, then uses Stefan Brain to run a CRO funnel review, generate static and UGC ad scripts, clone and customize a reference landing page (AlphaBrain) for a female audience, edit copy, images, and design elements, and create multiple hook angles with the Angle Finder. Throughout the demo he critiques the existing ad and landing page copy, highlights friction points, and shows how the platform suggests stronger hooks, pain‑point framing, and visual assets. He also walks through publishing options, integrations (Facebook Pixel, Google Tag Manager, custom subdomains), and previews AI‑generated video ads using SeaDance and LCX. Stefan notes current limitations (image handling, occasional reload issues) and shares usage stats (355 M impressions since launch, recent API integration). The video serves as both a product showcase and a live tutorial of how marketers can automate funnel creation, copy optimization, and creative generation with Stefan Brain.
