Wisdom is worth more
when it moves.

Before you talk to an investor, you should be able to recite — without a spreadsheet — your monthly burn, runway in months, gross margin, CAC payback period, and net revenue retention. These five tell an investor whether you understand your own business. If any feels fuzzy, that’s exactly the gap a fractional CFO closes in the first fortnight — long before the deck matters.

Runway = cash in bank ÷ net monthly burn. The discipline isn’t the sum — it’s updating it every month and acting at six months left, not three. At six months you can still choose: raise, cut, or grow into profit. At three, the choice gets made for you. Build a simple 13-week cash-flow view and review it weekly; it’s the single habit that separates the companies that survive a tough quarter from those that don’t.

Before any senior hire — full-time or fractional — write down what success looks like at 30, 60 and 90 days, in outcomes, not activity. “Rebuilt the model and closed the audit” beats “owns finance.” If you can’t write the 90-day outcome, you’re not ready to hire — you’re ready to scope. A fractional engagement is the low-risk way to get the scope right before you commit to a full salary.

The mistake established businesses make is treating modernisation as a rip-and-replace. The operators who get it right change one workflow at a time, prove the gain, and bring the team along — so the thirty-year-old strengths survive the upgrade. Start where the pain is measurable (cash visibility, order-to-cash, stock) and let early wins fund the next step.

You don’t need to code. Start by using a frontier assistant (Claude, ChatGPT) as a thinking partner for one real task this week — a board note, a market scan, a first-draft model. Learn to write a clear brief and to check the output with your judgment (which AI still lacks). Experience plus AI beats AI alone every time; the goal is to stay the smartest person in the room, now amplified.

The seniors who thrive treat each engagement as a fixed block — say a half-day, same days each week — and protect it. Set outcomes per month, not hours per day; communicate asynchronously between blocks; and resist scope creep with a simple line: “happy to take that on — let’s add it to next month’s plan.” Two or three engagements, deliberately spaced, is a portfolio; five unplanned ones is a scramble.

Every function is being re-shaped — finance by real-time data and automated close, marketing by AI content and attribution, operations by connected supply chains. You don’t need to master the tools; you need to know what’s now possible, so you ask better questions and spot what’s outdated. The Academy publishes short, plain-English briefings on exactly this — one function at a time.
