The CFO's Role in Shaping Founder Decision Making
A founder generally walks in the room with 50% of the decision already made. This person fits. This new market appears empty. This fundraising round looks promising enough to sign Friday. The upcoming play will either result in more solid construction during its second year of business or lead to construction that relies primarily on faith.
This phase is when the CFO has the opportunity to earn their keep, though it is less about the sheet on their screen and more about what happens after their sheet has been reviewed.
The Job Most Founders Assume a CFO Does
Ask almost any founder how they identify someone for this role, and you are likely to hear, “Someone who is good with accounting – they handle our closes, we send things in on time, and we put out a monthly sheet reflecting the business done." However, I allocate a significant portion of my compensation to finance in order to gain insights into future trends.
For people who build companies and don’t build finance into their plans, and for companies where there’s simply a lack of capacity, the cost of making business decisions based on instinct alone, is felt by everyone. When instinct is sufficient, the founder is creating a business driven by either a product or the consumer demand for that product or service.
Situations where founder instinct drives the business forward and where it encounters obstacles.
This process, however, often doesn’t include knowledge about which particular fund to raise capital from, at exactly the correct stage or whether to extend an additional line of credit, or to use the capital as it pertains to that stage of operations as opposed to the one down the street.
This area is the land of logic, of seeing ahead, and its territory that has belonged to CFOs. They do the detailed analysis and forecasting, helping founders see how a capital structure decision or a hiring choice impacts the runway in six months to two years.
The CFO warns of pitfalls, while the founder makes product and business decisions.
Report Or Reframe The Decision
This step distinguishes a CFO who drives decisions from one who just reports them. The founder wants to enter a new market. A solid thought. Immense enthusiasm.
Your average forecasting-style FP&A person will deliver their projections, attach some reasonable assumptions, then seek a stamp of approval. Your excellent decision-shaping CFO will reframe the thought in a different kind of language entirely. Instead of asking, 'Is this new market likely to succeed?’ they’ll ask, ‘How many months of runway will it take us to determine if the market can succeed, and what will our business look like if we enter the market months late?’
Your founder will hear "expansion", a prospect; and your CFO will hear "a bet measured in time- a commodity a small company will never recover".
By translating this, they’re changing the decision as it is, not just the description afterwards. The expertise lies in the translation. The founder identifies opportunities, while the CFO considers the months, the burn rate, and the costs associated with making mistakes.
Both perspectives need a seat at the table. The founder makes the big vision happen; the CFO makes sure it can happen.
Why Small Business Is the High-Wire Stage
A poor choice can be fatal for a start-up or small company because the balance sheet cannot support it; even one decision can feel like an instinctive gamble. You have a very limited capacity to endure bad decisions: your small business team depth isn’t there, nor is there a buffer on the financial statements.
In a Fortune 500 company, many hundreds of wrong decisions might be survivable, but in your 20-person enterprise, just a few could be cataclysmic. That’s why you must bring financial discipline to the decisions that need financial judgement, whether part-time, fractional or full, far earlier than many founders do.
Founders who postpone financial discipline until the business has sufficient capacity or feels "big enough" often miss the most important decisions that should be made early to ensure scalability. Clean companies have financial judgement applied early, often on very small decisions before they compound. Your role as CFO in that circumstance becomes a much quieter one: eliminating avoidable surprises.
A DSO that exceeds normal levels, cash burn that significantly outpaces revenue growth, and a deal term that appears fair at first glance but will result in penalties upon exit- are all red flags.
These issues gradually accumulate, one poor decision at a time, often without making headlines. Somebody must track the quiet drift. That’s the CFO role at the early stage.
Beyond The Numbers
Founders may have the naive image that their “ideal” CFO is the person who can uncover the magic numbers inside. It’s way more subtle than that. The best financial decisions a founder will ever make almost certainly have less to do with numbers and a lot more to do with whether someone’s willing to speak up for uncomfortable things early, while the checking account still has runway.
The sheer weight of decisions can crush a founder running a small business – there are products, people, customers, culture, and cash all piled on one's back; one can only handle so much.
A CFO’s role is to peel the cash decisions off the pile and bring them to a different light: a “gut decision” to an analytical decision and a grand vision to a survivable plan. And that’s all pre-reporting, pre-closing, and often pre-realisation for anyone else; while the founder is busy deciding where the company is going, the CFO ensures the company actually has a fare that can get them there.
The strongest companies are those where the roles of the founder and CFO intersect, allowing for flexibility and adaptation.
