I hold two fractional roles right now, plus my own projects. Head of product at one company, head of product and go-to-market at another. Both are real jobs with real ownership, neither is full-time, and the arrangement works.
It also failed the first time I tried it, for a reason that took me a while to see clearly. I was treating fractional as a smaller version of a full-time job. It's not. It's a different job that happens to occupy less of the week, and almost everything that goes wrong comes from that confusion.
The difference in one sentence
A full-time leader is present for the ambient information. A fractional leader isn't, and has to build a substitute or fail.
Everything else follows from this. Most of what a senior person knows about their organization didn't arrive through a formal channel. It came from a hallway remark, a tone in a meeting, a thing somebody said before the call started. That input is invisible and enormous, and when you're there two days a week, you get a fraction of it while still being expected to make decisions of the same quality.
You can't fix this with more meetings, which is the first thing everyone tries. Meetings are the most expensive possible substitute and they consume the time you were hired to spend on judgment.
What works is different in kind. Decisions get written down, with the reasoning attached, in a place that persists. Not because documentation is virtuous but because it is the only mechanism that survives your absence. When you are gone on Thursday and something comes up, the team needs access to how you think, not access to you.
The useful side effect is that this is better practice anyway. Organizations that write decisions down make better ones. Fractional work forces the discipline that full-time presence lets you avoid.
What clients get wrong
The most common failure is hiring fractional for capacity. A company is behind, they can't afford a full-time senior person, so they hire someone at three days a week and expect five days of output at a discount.
That never works and everybody ends up unhappy. If the problem is capacity, you need more hands, and a fractional executive is the most expensive hands you will ever buy.
Fractional works when the problem is judgment. You need someone who has done this before to make a small number of high-consequence decisions correctly and to give your team a structure for making the rest. That is genuinely compressible into two or three days a week, because the valuable part is not hours.
The second failure is hiring fractional for something that requires authority you haven't granted. If the role involves changing how people work, and the person has no standing to require anything, you have hired a very expensive advisor and given them an operator's title. The role fails and everyone concludes fractional doesn't work, when what did not work was the setup.
What the practitioner gets wrong
I will speak for myself here, because I made these mistakes.
Taking too many. Three fractional roles isn't one job. It is three jobs with three sets of context, three sets of politics, three sets of people whose names and histories you need to hold. Context switching between them costs far more than the calendar suggests, and the cost isn't in time, it's in the quality of attention you can bring to each. Two is my honest limit. I've tried three and did all of them slightly worse.
Not saying no early. In a full-time role, you can absorb a bad request and quietly deprioritize it. Fractionally, there is no slack to absorb anything. Every yes displaces something. This means having a much more explicit conversation about priority than a full-time person would need, more often, and earlier, which feels rude and is not.
Confusing being liked with being useful. The failure mode of a part-time senior person is becoming pleasant and inconsequential. You show up, you're helpful in meetings, everyone likes you, and nothing is different after six months. This is comfortable and it's the thing to guard against hardest, because the feedback signal is warm right up until the contract ends.
The economics, without the pitch
The case for the client is real and it isn't the cost saving people lead with. It's access. A company that cannot recruit a senior person full time, because of stage or location or budget, can get that person's judgment for part of a week. That's a genuine arbitrage and it's why the category exists.
The case for the practitioner is more mixed than the enthusiasts admit. Income is less stable, there are no benefits, and you carry sales overhead permanently: a fractional role ends, usually amicably, usually with less notice than a job would carry, and you need the next conversation to already be in progress. Anyone telling you this is a straightforward upgrade over employment is selling something.
What is genuinely better is variety and compounding. Seeing several companies at once means you see patterns nobody inside a single company can see, and that pattern library makes you better at the work. It's the closest thing to consulting's main benefit without consulting's main problem, which is producing recommendations you never have to live with.
If you're considering it
Take one role first, alongside whatever you are currently doing, and see whether you can actually do it well at that footprint. Most people discover in the first month whether they can operate without ambient information or not. Some can't, and that's not a character flaw, it's a fit question.
And be honest about which problem you're being hired to solve. If the answer is capacity, decline. You will not fix it, and the failure will be attributed to you.
