First Finance Hire Today vs. Ten Years Ago

In this episode of Run the Numbers, CJ Gustafson sits down with Ivan Makarov, Operating Partner at Andreessen Horowitz and former VP of Finance at Webflow, to explore what it takes to build a finance function from scratch inside a fast-growing startup. 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.
