Consultant COO

If you’re a company that requires the knowledge and expertise of a great COO, but doesn’t require them on a full-time basis, then a part-time portfolio COO or Strategy Consultant is the best option for you. We have a community of COOs who are able to work between 1-5 days a week, on a month to month contract, or a project by project basis.

A COO is often the best service for organizations who intend to invest in their finance team but need to know more about the status quo before investing. Our part-time COO services include: fundraising prep, commercial modelling, and an Operations department health check of your entire business. Clients range from early-stage start-ups, family businesses and Venture Capital funds. Please call us to discuss further.
