Fractional Executive Assistant
Senior executive assistant support, part-time. Strategic EA partnership for founders and leaders who need judgement and coverage without a full-time hire — what it costs, how it works, and how to find one in the UK.
What fractional executive assistants actually do
A fractional executive assistant is an experienced EA who supports one or more executives on a part-time, ongoing basis — typically 10–30 hours a week — bringing senior-level capability without the cost or commitment of a full-time hire.
Core responsibilities include
Inbox & calendar ownership · board/meeting prep and minutes · travel and logistics · project & vendor coordination · gatekeeping and prioritisation · light ops/process · investor relations support
Unlike virtual assistants, fractional EAs operate at C-suite level with discretion for confidential matters, board relations, and investor communications.
Senior EAs operate with autonomy and discretion, often as a proto–chief-of-staff. They handle confidential matters that require judgement, not just task completion. The 40+ hour test: if you can consistently delegate 40+ hours/week, consider full-time EA hiring. Fractional works best for strategic support that varies with business cycles.
Fractional EAs deliver 40-60% first-year savings versus full-time hire when factoring in loaded costs, recruitment, and ramp time.

When to hire a fractional EA
Need coverage and judgement, but not ready for 40 hours/week of consistent delegation. Perfect for strategic support without employment risk.
Variable workload that needs to flex up and down with business cycles, board meetings, fundraising periods, and growth phases.
Never had executive assistant support before — no employment commitment while learning to delegate and structure the role effectively.
Board meetings, investor relations, confidential matters require experienced EA, not junior virtual assistant or offshore support.
Company stage and EA needs
Seed/Series A: Founder needs coverage but not 40+ hrs/week consistent delegation · Series B/C: Variable workload around fundraising, board cycles, scaling phases · PE-backed/mature: Senior discretion for investor relations, board prep, confidential project coordination · First-time: Testing EA support without employment commitment while learning to delegate effectively
Most founders discover they need strategic EA support around the £2M-£5M revenue range when calendar complexity and stakeholder management outgrow founder capacity. Fractional works best for 10-30 hours/week of strategic coordination rather than full administrative coverage.

**The seniority difference matters**: fractional EAs bring C-suite experience, discretion with confidential matters, and proactive partnership versus task-based virtual assistant execution.
Virtual assistants (typically £800-£2,000/month, 5-20 hours) work well for routine administrative tasks, email management, basic calendar coordination. Fractional EAs (£1,500-£4,500/month, 10-30 hours) handle board prep, investor relations, strategic project coordination, confidential matters requiring senior judgement.
Employment vs partnership model
Full-time employment brings dedicated capacity but requires 2-4 months recruitment, £25k-£40k fees, full employment risk, and consistent 40+ hour workload. Fractional partnership delivers senior capability immediately with flexibility to scale up/down around business cycles, fundraising periods, board meetings.
