Fractional CFO and operator

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.

Former CFO, Pittsburgh Knights. Backed by the Pittsburgh Steelers, Bob Nutting, and Wiz Khalifa.

If you are a founder

You want to know what you actually get.

  • A model you can defend in a partner meeting.
  • A cap table that matches the signed documents.
  • A data room that is ready before the first request.
  • Someone in the raise with you, not commenting from the side.
If you are an investor

You are checking who runs the numbers.

  • The model ties to the books and the bank.
  • The cap table ties to the ledger, every SAFE, and every note.
  • Diligence requests get answered from one data room.
  • I take the finance questions on the call myself.

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.

08Questions

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.

Install structure before it becomes urgent.

If you are six to twelve months from a raise, or in the middle of one, a short call will tell us both whether there is fit.
