Jonathan Oh.
Fractional CFO for venture-stage companies. One operator, not a firm. Based in Pittsburgh, often in New York, and embedded in six companies today.
I have been a venture-stage CFO for eight years. Six of them were inside one company, the Pittsburgh Knights, from inception through three rounds of capital and more than $7M raised. The last two have been as an embedded CFO across several companies at once, in gaming, media, software, and AI.
The job, as I do it, is not advice. I build the financial model, the cap table, and the data room, then I run the raise alongside the founders. I set up the books when there is nobody to do it, I write the board pack, and I take the finance questions on the investor call myself.
I run all of it on a platform I built, Oh Ventures OS. AI drafts inside it. I decide what goes out. That is how one person carries six finance functions without any of them noticing the other five.
Six years, three rounds, one company.
I was with the Pittsburgh Knights from inception and left six years later as CFO of a company with more than 70 staff. The Knights were an esports and entertainment company backed by the Pittsburgh Steelers, Bob Nutting, and Wiz Khalifa. Over those six years I took the company through three rounds of capital. I built the financial architecture and the operating systems, and I was in the room each time an investor questioned them.
Three rounds means three sets of diligence, three cap table restructurings, and three board compositions. The model that went into each one was mine. So was the data room, the board pack, and the answer when the numbers were challenged.
Most of the operating work had nothing to do with spreadsheets. We ran the Knights Gaming Zone inside the Steelers stadium for all ten home games a season, a physical activation that put Madden stations in front of sports fans and gave brand partners logo placements and on-air shoutouts. Riot Games, Sheetz, McDonald's, eBay, and HyperX all shipped activations through the company.
In March 2020 every event on the calendar was cancelled inside a week. Three days later I was running a live Madden tournament from my apartment: two Steelers players, Benny Snell and Terrell Edmunds, against our professional Madden player, with Sheetz as title sponsor, on a broadcast rig I had put together over years of streaming for fun. Inside twelve months that one broadcast had become Knights Arena, an online event business working with Riot Games. The full story is here.
Four things I still run on.
Move when the market freezes.
The companies that act during a shock take share that takes years to build in normal times. When other event companies stalled in 2020, we ran.
The model is the business.
The deck is a summary of the model, not the other way round. Build the model first and let it tell you what the company is.
Smaller setup, faster execution.
A real broadcast company needed a control room and three weeks. We had a desk and three days. For an early company, smaller is faster.
Own the number before anyone asks.
Runway, burn, and dilution should be answerable in ten seconds. If they are not, the company is running on a guess.
I stopped advising and started embedding.
After the Knights I did what most finance people do after an operating run: I started advising. It took about two engagements to see the problem. Advice produces memos. Companies need the model built, the cap table reconciled, the data room filled, and someone on the call when the investor asks why churn moved. So I stopped advising and started embedding.
I also noticed that every fractional CFO carries a folder of spreadsheets from client to client, and every engagement looks a little different as a result. I got tired of that and built the system instead. Oh Ventures OS holds every company's model, cap table, cash, pipeline, and meeting notes in one place. Executives sign in to a live dashboard with an emailed code. Investors get a link to the cap table and the projections. Nothing to install.
AI runs inside it. It drafts the first version of a board update, categorizes the ledger, and summarizes a diligence request. I read everything before it leaves. I think that is the right division of labor for a CFO in 2026: the machine does the transactional work, and I do the deciding.
One operator, not a firm. When you hire me, you get me, on the call and in the model. I keep the number of companies small enough that this stays true.

The first sixty days are the build.
I plug into the tools you already use, read everything, and build the model and the cap table in the first six weeks. The data room opens by day sixty. After that we run: weekly numbers, a monthly close, a board pack on the same day every month, and the raise when it comes. How I work, in full.
If one of my companies is in your pipeline.
The model you receive ties to the books and the bank. The cap table ties to the signed documents, every SAFE and note included. Diligence requests come out of one data room, and I take the finance questions on the call myself. If something does not tie, tell me and I will show you why.
