If you’re already asking whether to bring in a CFO, you probably needed one a quarter ago.
Finance always feels like a “later” problem until it isn’t. By the time you feel the urgency, you’re reacting instead of deciding.
The five signs I see most often
1. The model hasn’t been updated since the last raise. The model you built for investors described a plan. Since then, hiring slipped, a channel underperformed and costs moved. If nobody has rolled the model forward, every decision is being made against a version of the company that no longer exists.
2. Burn is creeping up and nobody is sounding the alarm. It rarely jumps. It drifts: a tool here, a contractor there, a raise for a key hire. Without someone reviewing spend against plan every month, nobody notices until runway is months shorter than everyone assumed.
3. Metrics exist, somewhere, across six different dashboards. Sales has one number for revenue, finance has another and the board deck has a third. When people argue about which number is right, nobody is making decisions from any of them.
4. Headcount decisions are still made on gut feel. Hiring is the largest and least reversible spend most startups make. If you can’t show what a hire does to burn, runway and the plan, you’re betting the company on instinct.
5. Nobody can see runway past six months. Six months is roughly how long a fundraising process takes. If you can’t see beyond it, you can’t plan a raise from strength.
Doing it yourself isn’t free
Founders often think running their own finance is the lean choice. It saves cash and keeps them in control.
But every hour you spend in a spreadsheet is an hour you’re not growing the business. And without someone checking the work, the expensive things slip past: burn accelerating quietly, a model that no longer reflects reality, and numbers that worry investors before you notice them yourself.
In an early-stage company, decisions compound fast. Financial mistakes don’t take months to matter. They take days.
What changes when you bring someone in
The first month is usually about trust in the numbers: getting the close current, agreeing on one version of revenue and burn, and rebuilding the model on what’s actually happening.
After that, the work shifts to decisions. When to hire and who. Whether a pricing change is worth the churn risk. How much runway you really have under a bad quarter, not just a good one. When to start raising, and what story the numbers tell.
What you actually need
You don’t need a full-time CFO. You need someone who can turn noise into clarity: ask better questions, spot risks early, and help you run tighter.
That’s the difference between having numbers and understanding them. One keeps the books. The other keeps the company alive long enough to grow.
Common questions
What’s the difference between a fractional CFO and a full-time CFO?
A fractional CFO does the same strategic work, part of the time, for a monthly fee instead of a salary and equity. It fits companies that need senior finance judgment before they can justify a full-time executive.
Do I need a CFO if I already have a bookkeeper or accountant?
Usually, yes. A bookkeeper records what happened. An accountant handles taxes and compliance. A CFO uses the numbers to help you decide what happens next: hiring, pricing, cash planning and fundraising.
How soon should I bring someone in before a raise?
Ideally three to six months before you start. That leaves time to clean up the numbers, rebuild the model and know your metrics before investors ask.
