Fractional COO vs Interim COO: Cost, Scope, Fit
Interim COO fills a vacant seat full-time. Fractional COO builds the system part-time. Side by side on length, scope, cost, and which one you need.
Fractional COO vs Interim COO
One sits in the seat for a quarter. One builds the system from the side. The right pick depends on what's actually broken.
01 What each engagement actually is
Seat is empty: COO left, mid-integration, fundraise
Operation is messy: no cadence, no dashboards
A runway to the permanent hire
A machine that runs without them
What is actually broken right now?
COO left. Mid-integration. Fundraise needs an operator. Hire an Interim COO. Fill the chair, then run the search.
Decisions stuck on your desk.

What's the difference between a Fractional COO and an Interim COO?
An Interim COO is full-time in the seat for a fixed window. 3 to 9 months. You hire one while you search for the permanent COO, or to stabilize after a departure. A Fractional COO is part-time and ongoing. 10 to 20 hours a week. They build the system without ever sitting in the chair.
When does an Interim COO make sense?
Your COO just left. You're mid-fundraise and need an operator named in the deck. You're integrating an acquisition and need someone full-time for 90 days. Interim is the right call when the seat must be filled: now, and the search for permanent will take a quarter or two.
When is fractional the better fit?
You don't need someone in the seat. You need the system built around it. Cadence. Dashboards. Hiring loop. SOPs. A fractional engagement runs $8K–$25K/mo and leaves behind a machine. An interim engagement runs $25K–$50K/mo and leaves behind a runway to the next hire.
Yes. An Operating Partner. Not full-time. Not system-building. In the room for the move: the renewal, the hire, the comp plan, the customer call. If the bottleneck is decisions you've been carrying alone, neither interim nor fractional is the seat. That's an Operating Partner.
What size company is each one for?
Interim COOs show up most in $20M+ companies with a real org chart and a vacant seat. Fractional COOs fit $3M–$30M. My Operating Partner work is built for founder-led businesses doing $5M–$30M where the founder is still the approval layer on hiring, pricing, and the top three customers.
How fast does each one start producing?
An interim COO spends 30 to 60 days learning the business before decisions improve, because they inherit the whole seat. The first step is a short application, followed by a 30-minute call if it's a fit. Then a scoped plan: three moves, an owner on each, the target number, and what stops. Then month to month, scoped to team size and markets.
