Growth Engines with AI Agents - S2 Ep 4: Build an Agent That Syncs Custom Audiences Everywhere

​Season 2 is a live build, not a webinar.

​Every week from September through November, we build an AI agent on air, live, from the command line, with the Model Context Protocol. Real ad accounts, real budgets, real results read back on the next episode. No slideware.

​This season goes deep on the part of growth marketing that decides everything else: audiences. Who you reach, how you build the list, how it syncs to every platform, and how you know it worked. Every episode is built around one question: what does it take to build an agent that can actually do this job.

​Ep 4: Build an agent that syncs custom audiences everywhere. One CRM list, one agent, matched audiences on every major ad platform, live: match rates, lookalikes, exclusions, and the sync pipeline that keeps it fresh.

​You leave with the actual setup. Every episode ends with the exact steps to build and run the same agent on your own machine: the Synter connection, the commands, the skills, and the guardrails, exactly how I run it myself.

​Hosted by Joel Horwitz, founder of Synter, the agent media buyer operating across 20+ ad platforms.
