A few years ago, I was advising a startup on growth strategy, go to market and investor relations. Mid-discussion, one of the founders turned to me and said, โWhy donโt you just be our CFO?โ
I shrugged it off, โIโm not an accountant.โ In my mind, CFOs were in-house, full-time, compliance-focused, audit-ready and deeply technical. I was a strategic adviser, not a finance executive.
But that comment stuck. Not because I was going to take the job, but because it challenged my own assumptions. Maybe the definition of a great CFO had evolved.
Great CFOs are business operators disguised as finance leads
Todayโs CFOs are no longer financial historians. Theyโre business thinkers who understand how to turn capital into outcomes.
Dave Stephenson, for example, wasnโt a CPA when he joined Airbnb as CFO. He came from Amazonโs operations team. What he brought wasnโt audit expertise, it was operational insight, scale experience and a deep understanding of growth metrics. During Airbnbโs toughest years, that commercial mindset made all the difference.
Financial fluency is necessary, but strategic judgment is priceless
CFOs still need to understand unit economics, cash flow dynamics and shareholder expectations. But more importantly, they need to know which levers to pull and when.
Budgeting is one thing, prioritizing is another. Do we hire 10 more sales reps? Extend our runway by 6 months? Raise a new round, sell the company, or wait? These are the real questions founders face. And a great CFO helps answer them, not with theory, but with grounded insight and scenario planning.
The best CFOs bring clarity to chaos
Startups are messy. Thereโs too much data, too many bets and constant change. A CFOโs role is to bring structure, not through bureaucracy, but through focus.
The strongest CFOs help teams make better decisions faster. They simplify complexity, define healthy KPIs and create alignment between vision and execution. Theyโre not just asking โHow much are we spending?โ theyโre asking โIs this moving the business forward?โ
When I work with founders, this is where I spend the most time: bringing financial perspective to strategic conversations.
In a world where capital is scarce and execution speed matters, the role of the CFO has become far more entrepreneurial. You donโt have to be a CPA to be a great CFO. But you do need to think like a founder, and act like a partner.
