A year ago, Barbara Jovanovic showed us how she ran a marketing agency with zero employees. Since that episode, her business has grown 5X, and she's still a team of one. In this episode she opens up the exact agentic system that made it possible, and gives it away for free.
Barbara walks Kipp and Kieran through how she went from using AI as a chat box to running a full multi-agent content operation: connected MCPs for client context, dedicated agents for research, writing, and cold review, a self-learning performance loop, and the "Founder Ghostwriter Setup" skill she uses to run founder-led content for every client.
📌 WHAT WE COVER:
→ How Barbara 5X'd her one-person agency in 12 months
→ Why she moved everything from ChatGPT to Claude Code
→ Connecting MCPs so AI has full client context (Granola, Slack, Buffer, Google Drive)
→ The Slack workaround for pulling in client meeting transcripts
→ Where great founder content actually comes from
→ Why monthly founder "insight calls" beat any automated interview
→ Why writing guides fail and processes win
→ Inside the skill: one agent per post, cold reader review, performance loops
→ The self-learning system that improves every week's batch
→ Live demo: running the Founder Ghostwriter skill on a real client setup
→ How the cold review agent catches AI slop before you ever see it
→ The context docs that make or break output quality
