FAQ
Questions Prospective Clients Ask
What does a fractional CFO actually do?
A fractional CFO is a senior finance executive engaged part-time or on contract who provides the same strategic leadership as a full-time CFO — financial planning, forecasting, fundraising preparation, board and investor reporting, cash management, and month-end close oversight — so a company gets experienced financial leadership without the cost of a full-time hire.
When should a company hire a fractional CFO instead of a full-time one?
A company should hire a fractional CFO instead of a full-time one when it needs senior financial leadership but is not yet large enough to justify a full-time executive salary — typically from early revenue through Series A — and should move to a full-time CFO once its scale, reporting complexity, and budget make a dedicated hire worthwhile.
What kinds of companies do you work with?
I work with technology and fintech companies — including SaaS, marketplaces, and data-heavy businesses — where reliable financials, clean reconciliation, and credible reporting are essential for attracting institutional investors and passing due diligence.
What is MatchData.ai?
MatchData.ai is reconciliation software Doug built over a decade of CFO work and patented (U.S. Patent 11,475,026), which matches messy financial data across two systems and reports three outcomes — matched, unmatched, and uncertain, where more than one combination balances and the software refuses to guess.
