Best fractional COOs: firms and solo practitioners

A fractional COO turns a founder's to-do list into an operating rhythm. The work is unglamorous and specific: an accountability chart with one owner per function, a weekly leadership meeting that ends with decisions, a scorecard of the numbers that matter, and the handful of processes that still route every question through the founder. Many fractional COOs work as EOS integrators, so if you already run EOS or plan to, look for that on the row. Buyers are usually 20 to 100 employees and $3M to $30M in revenue, and the reason is almost always the same: the founder has become the bottleneck. Published retainers run $3,500 to $15,000 a month, with one day a week typically $5,000 to $10,000. Rows on this page show the revenue bands each firm serves, its stated minimum term and fee where published, and whether it also coaches integrators and second-in-command leaders.
