Fractional CFO · Boston, MA

a million-dollar
company.

Most founders are flying blind on their finances — making gut-feel decisions that quietly cost them. StackedCFO brings Big 4-caliber financial leadership to ambitious entrepreneurs without the full-time price tag. Strategy, systems, and AI-powered automation — built to scale with you.

The Problem

Growing revenue isn't the same as building a real business.

Ambitious founders hit a wall — not because they lack vision, but because their financial infrastructure can't support their growth. No real reporting. No cash flow visibility. No financial systems that scale. Decisions made on gut feel instead of data.

I've spent 13+ years inside Big 4 firms and PE-backed companies fixing exactly this. Now I do it for founders who see $1M, $10M, $100M ahead — and need a CFO-level partner to help them get there.

"The founders who reach $10M aren't smarter — they just have better financial infrastructure than the ones who stall at $2M."
— Casper Zhao · Founder, StackedCFO

Why It's Different

Big 4 depth. Founder-first thinking.

Most fractional CFOs come from industry. I came up through PwC and BDO — building technical accounting chops on some of the most complex transactions in the market. That rigor is now yours.

01
CPA with Big 4 Pedigree
13+ years across PwC, BDO, and CFGI — advising PE-backed companies, public registrants, and IPO candidates on the most complex financial reporting situations. Active CPA license, Commonwealth of Massachusetts. You're not getting a generalist — you're getting someone who has sat across from CFOs, Audit Committees, and PE sponsors and delivered.
02
AI-Native from Day One
Most CFOs are still using Excel from 2010. StackedCFO builds AI-powered financial workflows — automated reconciliations, Python-based reporting, dynamic dashboards — that make your finance function run like a company 10x your size. The tools exist. Few CFOs know how to actually deploy them.
03
Operator Experience, Not Just Advisory
I've served as acting Controller for PE-backed platforms — running close cycles, managing teams across three continents, compressing month-end close from 20 to 5 business days. I don't just advise on what should happen. I've done the work and can build the systems alongside you.
04
Transaction-Ready at Every Stage
Whether you're raising a seed round, closing a Series A, preparing for acquisition, or planning an eventual IPO — I've supported $2B+ in capital markets transactions. Your financials will be investor-grade before you need them to be.
How It Works

From first call to financial clarity

Step 01
Discovery Call
30 minutes. We talk through your business, your financial situation, and where you're trying to go. No pitch — just an honest conversation about whether and how I can help.
Step 02
Financial Diagnostic
I assess your current financial infrastructure — reporting, close process, cash flow visibility, and gaps. You get a clear picture of where you are and what needs to change.
Step 03
Build & Implement
We design and implement the financial systems and processes your business actually needs — customized to your stage, industry, and goals. Not a template. A real build.
Step 04
Scale With You
Ongoing fractional CFO support as you grow — monthly reporting, strategic guidance, investor readiness, and AI automation that compounds over time. The infrastructure scales as you do.
Who This Is For

Founders who know they're worth more than their current financials show.

You're a great fit if…

You're doing $200K–$5M in revenue and growing fast, but your financials are a mess or invisible.
You see yourself building a $10M+ company and want the financial infrastructure to match that ambition now.
You're preparing to raise capital, get acquired, or bring on investors and need investor-grade financials.
You're making important business decisions without reliable financial data — and you know that's a problem.
You want a real CFO partner, not just a bookkeeper who sends you a P&L once a month.

This probably isn't for you if…

You just need basic bookkeeping. That's important but it's not what StackedCFO does — we go several layers deeper.
You're not yet generating revenue. Pre-revenue companies need a different kind of help at this stage.
You want someone to just execute tasks, not think strategically. StackedCFO is a thought partner, not a data entry service.
You're a large enterprise with a full finance team already in place — this is built for growth-stage founders.
