Top Takeaways:

🚀Turn every feature launch into a full-funnel growth engine
Don't just ship and announce. Coordinate each release across organic posts, landing pages, and refreshed ad creative simultaneously so earned attention compounds into paid efficiency.

💰 Train a custom GPT on your own winning ad copy
Feed your top and bottom performing Meta and Google copy into a custom GPT, then use it to rapidly translate brand messaging into proven high-performing ad formats. It turns institutional knowledge into a scalable creative tool.

🤖Directing AI agents is the new core marketing skill
The future of marketing isn't just using AI tools but directing agents to handle messaging, storyboarding, ad creation, and localization, all grounded in your creative taste and brand direction.
