About Us

MAIN CFO

Who We Are

Main CFO provides fractional financial leadership to CEOs scaling service businesses from $5M to $50M in revenue. We work with operationally mature companies that need strategic financial infrastructure, capital allocation frameworks, forecasting discipline, margin analysis, and institutional-grade reporting, without the overhead of a full-time CFO hire.

With decades of experience building financial infrastructure across professional services, e-commerce, healthcare, marketing, manufacturing, legal, and consulting firms. We support businesses always as embedded financial partners, not external consultants. We're selective about engagements because the work only delivers results under specific conditions: operational maturity, growth ambition, and strategic urgency.
