IN SHORT

The category is crowded and the label is slipping. Here's why we built a firm of operators instead, and how to tell which one you actually need.

The fractional CFO market sells you someone's spare time. It doesn't sell you a result.

Search "fractional CFO" and you'll find a directory. Profiles, day rates, availability calendars. The pitch is always the same: senior finance experience, a few days a month, no full-time commitment. It sounds efficient. In practice, it means you're buying hours, not an outcome, and the incentive on the other side of that arrangement is to keep the hours going, not to close the gap that brought you there in the first place.

That's the structural problem with the category, not a complaint about the people in it. A significant proportion of fractional FDs and CFOs have never actually held the seat in a real business. There's a difference, and founders eventually feel it: usually at the exact moment they need the judgment most.

A finance operator firm sells the fix, not the time.

Pillr is built the other way round. We're a firm of operators who've run finance functions for real: through bank pressure, investor scrutiny, and the calls that decide whether a deal happens. The engagement is scoped to what needs to change, not to a day count. Sprint, Build, Scale, Deal: each one is productised, with the outcome fixed before anything is signed.

That difference shows up fastest in how the relationship starts. A fractional hire usually begins with a role description. A Pillr engagement starts with a diagnosis: what's actually broken, what it's costing you, and what has to happen first. Most businesses that think they need a CFO need a diagnosis first. Hire before you've found the real problem and you pay twice.

How to tell which one you actually need.

If you know exactly what the role should do day to day, and you want someone senior filling it part-time, the fractional model can work. If you're not sure what's actually wrong (the numbers are late, the board doesn't trust the forecast, a bank or investor conversation is coming and the finance function isn't ready for it), you need someone to find the problem before you hire for it. That's what Sprint exists for: a fixed-duration diagnostic that names the real issue in plain language, then hands you a prioritised plan.

A finance function that only reports what happened is a cost. One that shapes what happens next is an asset. Most scaling businesses have the former when they think they have the latter. The question worth asking before you hire anyone, fractional or otherwise, isn't "how many days a week." It's "what is actually holding us back, and who has done this before."
