I'm John Fong — fractional CFO, AI finance builder, and someone who learns in public.

I've spent 25+ years inside finance functions at every stage of a company's life — bootstrap to IPO, private to public, startup to scale. I've been the person building the model at 2am before a board meeting and the person presenting to institutional investors on a roadshow.

I founded F28 because the fractional CFO market has a gap: most fractional CFOs give you advice. Very few build you anything. I want to build the system, train your team, and leave your finance function materially better — and smarter — than I found it.

Over the past two years I've been rebuilding finance workflows with AI at the core — not as a side experiment, but as the operating model. I've done it at my own firm first. I share every experiment, every prompt, every mistake on LinkedIn. Because the best way to get a team to adopt AI isn't a memo. It's showing them what's possible — in real time, with real work.

Excel has been around 40 years. It's not going anywhere. It's just being reimagined. And that's exactly where I start — with the tools your team already lives in, and AI layered on top.

I work with a small number of clients at a time. That's by design.

The 70/30 Principle

AI gets you 70% of the way there. The last 30% — validation, stress-testing, strategic judgment, board communication — is where the CFO earns the seat. That last mile still belongs to the subject matter expert.

What F28 stands for
01
Builder, not advisor

F28 doesn't just tell companies what to do. It builds the system, implements the workflow, trains the team, and hands off something that runs. Every engagement leaves a tangible artifact.

02
AI as infrastructure

AI is not the product — it's the leverage mechanism that makes senior CFO judgment accessible at a fraction of the cost. F28 was AI-native before it was a selling point.

03
Learning in public

F28's credibility is built in real time — every experiment, prompt, and mistake shared openly. Transparency is the differentiator in a market where most advisors hide behind polished decks.
