Explain it simply
This agency looked at its best-selling ads for past clients and turned them into fill-in-the-blank patterns, like recipes for an ad. To make new ads, AI fills a pattern with a new brand's details, and AI avatars (computer-made people) read the scripts for video ads. People still choose which ads run and how much money goes behind each one.
What was done
The agency fed AI its highest-converting client ads and pulled out 20 to 30 proven ad structures. New campaigns are built by filling those templates with each brand's details, enough one-off ads to fill a client's sales calendar. HeyGen and Opus produce videos with AI avatars reading the scripts, and Claude Code builds landing pages on Vercel, runs split tests and watches conversion rates.
How it went
He cites clients spending $3,000 to $5,000 a day on these campaigns. He says the team moved budgets from campaign-level (CBO) to ad-set-level (ABO) because AI lets them scale each ad set based on results. There are no client names, ROAS or before-and-after numbers, so the result is his description.
