Quick answer
A controller manages the accuracy and integrity of your financial records — the backward-looking function of closing the books, reporting historical results, and ensuring accounting compliance. A CFO provides forward-looking financial leadership — strategy, fundraising, investor relations, and major financial decisions. Controllers are about precision; CFOs are about direction.
Most growing companies need a controller before they need a CFO — accurate books must come before strategic financial leadership. Once you're fundraising, managing complex capital, or making large strategic bets, a CFO (often fractional at first) becomes essential. Think of the controller as the engine room and the CFO as the navigator.
