How to Save 90% of Your Ad Budget with AI UGC
Steve P. Young (App Masters) talks with Stav Zilbershtein, co-founder and CEO of MaxFusion, about AI-generated UGC ads. Stav demos MaxFusion's competitor ad research (Cal AI), hook repurposing and two winning AI ads for Cantina Labs, and argues AI ads work when they don't pretend AI people are real (Ryze's AI singing-drama and apology ads as examples). Steve shares his plan to run MaxFusion-made ads for his own fitness app in a $300/day trial campaign. Ends with live audits of a photo-cleanup app (PX) and a CrossFit app (WOD App).
