Part-Time CFO SF

A part-time CFO gives a San Francisco business ongoing senior finance leadership one to three days a week — without the salary, equity, and overhead of a full-time hire. Hayat Amin runs the part-time CFO seat for founders and scaling startups across San Francisco on a fixed monthly retainer, and flexes up around the moments that matter.

What ongoing part-time looks like

• A steady cadence. One to three days a week, plus daily Slack, so finance never goes dark between visits.
• Month-end that closes. A reliable close and a board pack that ships on time.
• Fundraise-ready, always. The model and data room stay current, so a raise doesn't start from zero.
• Runway you can see. Rolling forecasts and clear levers, reviewed every cycle.
• Flex. More days around a raise or board meeting, fewer in quiet months.

Who it suits

Part-time works best for San Francisco founders past the bookkeeper stage but not yet at full-time-CFO scale — Seed through Series B — who want a senior operator in the business every week rather than a firm rotating faces. If your need is instead urgent full-time cover for a fixed window, that is an interim CFO.

Part-time, fractional, or interim?

Part-time and fractional are the same ongoing model. Interim is full-time cover for a fixed window. See how Hayat compares to other San Francisco providers in the 2026 Best Fractional CFO SF ranking.
