Fractional CFO
Quick definition
A part-time, ongoing CFO who owns strategy, forecasting, and fundraising for a fraction of a full-time hire's cost.
A fractional CFO is an experienced finance executive who works with a company part-time on an ongoing basis, typically 15-40 hours per month, owning strategic finance: forecasting, budgeting, board reporting, fundraising preparation, and capital allocation. Startups use fractional CFOs to get CFO-level judgment years before a full-time hire (often $200K-$400K in total comp, higher at growth stage) is justified. Distinct from an interim CFO, who works full-time for a defined transition period. Outsourced CFO, virtual CFO, and part-time CFO are largely synonyms for the same engagement model.
