How do top founders build content engines with AI (repurposing one idea into ten formats)?

The pattern is always the same: create one dense pillar piece (a podcast, video, or newsletter), then let AI atomize it into clips, threads, LinkedIn posts, and carousels for every platform. Sabrina Ramonov batches one Saturday of filming into a full week of output across eight platforms; Justin Welsh turns one idea into 16 posts with a simple matrix. You supply the original thinking once, AI and a scheduler handle the other nine formats.

A quick orientation. The real value is below: resources worth your time, from people who've actually done it.
