Fractional & Interim CFO · Growth-Stage Tech

Fractional CFO leadership,
built for your next stage of growth.

I'm an embedded fractional CFO for small-to-mid-market and growth-stage companies — board-ready and IPO-tested. I run the full finance function and add specialized depth where the economics get technical: SaaS & subscription economics, product & gross-margin finance, and supply chain — all held to board-, investor-, and lender-grade standards.

Everything I build runs on repeatable, AI-driven workflows — board decks, cost models, and lender/investor packages that stay precise and auditable as you scale, not one-off spreadsheets rebuilt every cycle.

One fractional CFO.
The full finance function, with specialized depth by business model.

As your fractional CFO, I own the forecast, the cash, and the numbers behind the decisions — a complete finance function for a small or mid-market company. On top of that, I bring real depth in the areas that make or break the model: SaaS and subscription economics, product and gross-margin finance, and supply chain — all reported to board, investor, and lender standards.

The Role

Fractional CFO

Embedded finance leadership for companies that need CFO-level thinking before they can justify a full-time hire. I run the complete finance function — planning and close, cash and forecasting, go-to-market and sales finance, board reporting and fundraising support — and bring the specialized practice areas below to bear wherever they create the most value. For a small or mid-market company, it's a full finance function in a single engagement.

  • Cash flow management & forecasting
  • Fundraise & runway planning support
FP&A & Planning

Capital Markets & Investor Reporting

Not a separate service — the reporting layer under everything above. Whatever the practice area, the output is built to satisfy the people who scrutinize your numbers: your board, your investors, your lenders, your PE sponsors, and your auditors. I've reported across the full ownership lifecycle — public company, PE-owned, and back to public again.

  • Full M&A lifecycle: take-private → PE → strategic sale
Diligence-Grade Rigor
  • Automated covenant & investor workflows
  • Sponsor / lender standards, not just board optics

CFO
OPS

CFO judgment with hands-on technical depth.

Few fractional CFOs have modeled a GPU cluster's unit economics, costed 10 million SKUs, or rebuilt a SaaS retention model — and the specialists who have rarely also run a board meeting or prepped an S-1. I've done both — at Palo Alto Networks I built the AI-compute cost models and served as Interim CFO of a 600-person division. Whether you're a SaaS, product, or physical-goods company, that combination is hard to find in one person.

A company at Series B usually doesn't need a full-time CFO yet — but it absolutely needs CFO-level thinking. What separates the businesses that scale cleanly from the ones that hit financial walls is usually this: someone in the room who's done it before.

I'm a fractional CFO who has run the finance function for divisions and companies through two IPOs (ThredUp, Leapfrog) and a $1B+ capital line of business at Dolby Laboratories. For a small or mid-market company, I'm a complete finance function. And on top of the standard CFO toolkit — planning, cash, close, go-to-market and sales finance — I bring depth in the areas that quietly decide margins and growth: SaaS & subscription economics, including the compute and cloud costs underneath them; product finance — R&D, product P&L, and gross-margin management; and supply chain & operations — the costing, inventory, and logistics layer beneath the P&L. Every engagement is reported to board, investor, and lender standards.

A thread runs through all of it: I build the workflow, not just the deliverable — repeatable and auditable, not a one-off spreadsheet that only works once. At Palo Alto Networks I drove a ~20% reduction in MDR and MTH managed-services compute spend by reconciling open tenants against customer-paid contracts and permitted usage — through business-partner interviews and deep Tableau analysis — and recovered $1.7M in supply-chain balance-sheet cash in 90 days through found inventory, return-to-vendor recovery, and unconverted Try & Buy. I'm completing an MBA in AI Product Management alongside this work, bringing modern tooling to finance processes that used to be manual and one-off.

Across a 30+ year career — including 15 years in senior finance and operations roles at Poly (formerly Plantronics), where I was a President's Award recipient among 3,500+ employees — I've learned that the businesses that scale best are the ones whose finance leader actually understands what's being built, not just what it costs.

Working with me means a partner who's been through IPOs, capital deployment at scale, and hands-on product, compute, and supply-chain cost builds — not a consultant who's only read about them.

"The best fractional CFOs don't just close the books — they give you the financial clarity to make bolder strategic bets."
