fractional executive assistant

A fractional executive assistant is a senior EA who splits their working week across two or three clients. You buy a share of their time rather than all of it.

The model exists because of a mismatch. Most founders do not have forty hours a week of executive-assistant work, but the work they do have needs judgement rather than task execution. Hiring full-time is expensive and underused. Hiring junior is cheap and does not solve the problem. Fractional sits between them: senior capability at partial cost.

What "fractional" specifies: how many hours you get, and that the assistant is shared.

What it does not specify: whether the work is managed, whether processes are documented, whether anyone covers absence, or who is accountable if quality slips. Those vary enormously between providers using the same word — which is why comparing fractional services on hours and price alone tells you very little.

The scope is the same as a full-time EA. The difference is volume, not capability.

A well-scoped fractional engagement handles all of this within its hours. The constraint is not what they can do. It is how much.

When full-time is genuinely right. If the work fills a week, if you need someone physically present, or if the role extends into personal and household matters you would not send outside the business — hire. We will say so on the call.

When fractional wins. When you need senior judgement now rather than in four months, when the volume is real but not forty hours, or when you are not yet sure how much support the business needs and a permanent hire is a large bet to place early.

Three points where "part of a person" stops being enough, and they arrive in this order.

The shared week collides. When two of a shared assistant's clients have a busy week at once, something gives. Usually the client who complains least. This is not bad faith — it is arithmetic, and it is structural to the model.

The process lives in one head. Six months in, a good fractional EA is genuinely valuable, and none of that value is written down. Ask what happens if they take a fortnight off, or leave. If the honest answer is that work pauses or context is lost, you have a continuity exposure that the hourly rate does not price.

The work spreads across systems. Fractional works cleanly inside an inbox and a calendar. When it extends into CRM hygiene, customer support and meeting operations — with handoffs between them — you need a documented process rather than a capable individual, because the failure mode is no longer "too busy" but "nobody knew that was theirs."

None of this makes fractional the wrong choice. It makes it a choice with a threshold, and knowing where the threshold sits is worth more than another comparison table.
