In a post on X, Georgi said a preview of SB1.5, a new StefanBrain model, launched the prior week. He said the model produces better copy and sharper analysis than the current version, while describing it as more creative and smarter. StefanBrain describes itself as an agentic marketing platform for DTC brands covering research, copywriting, creative, conversion-rate optimization, video generation, landing pages and media buying. It lists plans at $499 a month for Base, $999 a month for Elite and $5,000 a month for the application-only CA Pro plan, aimed at businesses with more than $3 million in annual revenue. The company says brands spending more than $100 million monthly on ads use the platform, naming VShred, Vidalytics and NativePath. StefanBrain says it is trained on Georgi’s proprietary IP, including more than 1,500 in-depth copy and funnel reviews and the RMBC Method. Georgi says he began his direct-response copywriting career in 2011 and has individually written more than 70 marketing pieces that collectively grossed more than $1 billion. Before StefanBrain, he built FreeAdCopy.com, which he describes as an AI SaaS tool for short-form copy, and launched a seven-figure AI-powered copywriting agency. --- ## Companies in this story - Stefanbrain: https://www.gobignews.com/company/stefanbrain --- ## X profiles in this story - @stefangeorgi: https://www.gobignews.com/profile/stefangeorgi
