Who We Are

MightyCFO is a management consulting firm focused on providing financial guidance, strategic planning, and tactical support to early stage startups and small businesses.

We believe that startups often lack the financial oversight and expertise needed to create sustainable business models, optimize fundraising, and drive value through capital efficiency. We understand Finance and Operations overlap immensely within small organizations and we know that success in business boils down to people and relationships. We are passionate about small business and are here to reduce the rate of business failure.

Our mission is to cultivate startup success by working side by side with founders to build healthy businesses that deliver real value to the world.


Our Values = ARR

  • Accretive – Our purpose is to drive enterprise value for our clients.
