The CFO you bring in before you can hire one.
I embed in venture-stage companies. I build the model, the cap table, and the data room, then run the raise alongside you.

“We had a product and no infrastructure. Jonathan came in and built the financial model, cap table, data room, and pitch deck. The first investor meeting we walked into, we were ready.”
“Most fractional CFOs hand you a spreadsheet. Jonathan installed an operating system. The difference shows up in every board conversation.”

Jonathan Oh
I was CFO of the Pittsburgh Knights for six years, from inception through three rounds of capital. I built the financial architecture and the operating systems, and scaled the team past 70.
Since then I have worked as an embedded CFO across gaming, AI, SaaS, and entertainment. I am one operator, not a firm. When you hire me, you get me.

The engagement, as a term sheet.
- Structure
- Embedded retainer, or a defined project.A project is one outcome: a model build, a data room, a capital narrative, or an operating reset.
- Term
- Six months minimum on retainer. Most continue open-ended.
- Compensation
- Cash, equity, or a deferred mix when a raise is close.
- Seat
- Fractional CFO or COO. I own the model, the cap table, reporting, and the raise.
- Handoff
- When you hire a full-time CFO, I hand over the system and train them.
- Out of scope
- Audit, tax filing, legal advice, and broker-dealer activity.I set up the books and run the close until you need a bookkeeper.
What founders ask first.
What does a fractional CFO do for a startup?
I run your finance function part-time. That means the financial model, the cap table, board reporting, the data room, and the raise. A bookkeeper records what already happened. I work on what happens next. Capital strategy vs. bookkeeping →
When should a startup hire a fractional CFO?
Six to twelve months before a raise is the usual answer. The other trigger is an investor asking for numbers you can't produce quickly. When to hire a fractional CFO →
How much does a fractional CFO cost?
My minimum retainer runs about 20 to 25% of what a full-time CFO costs. I take cash, equity, or a deferred mix when a raise is close.
How long until we're investor-ready?
Usually 30 to 60 days from kickoff to a model and a data room an investor can open.
What stages and sectors do you work with?
Pre-seed through Series A. Right now that's media, software, gaming, esports, and AI companies in the US and Canada.
Where are you based?
Pittsburgh, with regular time in New York. The work is remote-first, and my current companies are in New York, Florida, Houston, Los Angeles, Madison, and Toronto.
What I have been thinking about.
The blind spot every full-time team has: its own documents.
