Frequently asked questions
What does a part-time CFO cost compared to a full-time hire?
A fractional CFO engagement typically costs a small fraction of a full-time CFO's salary, benefits, and equity. You get senior expertise scoped to the hours your business actually needs.
What is the difference between controller and CFO services?
Controller services look backward - accurate closes, statements, and controls. CFO services look forward - strategy, forecasting, fundraising, and growth decisions. Most clients start with controller work and layer CFO support as they grow.
Do you support fundraising and M&A?
Yes. We prepare data rooms, build financial models, support due diligence, and produce valuations for raises, acquisitions, and exits.
