He Manages $100M in Ad Spend With a Trick Nobody Tried Yet

What if the tools everyone is already using for coding could also run your entire company's back office? Seva Ustinov manages over $100 million in ad spend and has quietly built a system inside Cursor and Claude that lets him treat documents, emails, pitch decks, and company strategy the same way developers treat code, all stored in one structured file system his AI can instantly read and act on. In this conversation, you will learn how Seva uses a single prompt to generate investor-ready documents without uploading files manually, how layering AI outputs on top of each other creates compounding leverage across your whole team, and why storing your company knowledge in a GitHub-style repository beats any chatbot add-on you have tried. If you have ever felt like AI tools are useful but disconnected from how your business actually operates, this episode shows you a smarter way to build the whole system.
