Ivan shares lessons from the trenches—how to decide between outsourcing and hiring in-house, what makes a great first finance hire, and why early-stage companies often run out of cash before they run out of ideas. He also dives into fundraising pitfalls, audit readiness, and the tools that make up a modern finance stack. Beyond the spreadsheets, Ivan opens up about the shift from operator to venture partner, the value of helping founders avoid his past mistakes, and what makes an offsite actually work.
