Fractional Executive plain-English.

The model exists because executive judgment does not scale linearly with company size. A thirty-person company makes maybe a dozen genuinely executive decisions a quarter. Hiring a full-time CXO to make twelve decisions means paying for roughly 480 hours of presence to get about forty hours of value, and then finding the person something to do with the rest — which is how companies end up with an expensive executive rebuilding a dashboard nobody asked for.

Fractional executives are typically brought in for one of three reasons: a function has outgrown the founder (finance past the bookkeeper, engineering past the first five hires), a specific transition needs senior hands (a fundraise, a migration, a certification), or a bad full-time hire has to be unwound without leaving the seat empty.

The two failure modes are worth naming. The first is the advisor in executive clothing — someone who joins calls, has opinions, and owns nothing; you can tell within three weeks because no decision has actually been made. The second is under-scoping: two days a month for a function that needs two days a week, so the fractional CXO spends every session catching up and never gets ahead of anything.

Fractional is not the same as interim. Interim is full-time for a fixed runway, usually covering a departure. Fractional is part-time and open-ended, and it is bought for judgment rather than coverage — which is also why it can be ended inside a single billing cycle, and why the good ones write that clause themselves.
