Head of Finance

The Role

You’ll be finance hire #1 at Comfy. Comfy is growing fast with 4 million users, a fast‑scaling cloud business, and a fresh $30M raise. So far we’ve run finance out of spreadsheets, outsourced bookkeeping, and founder intuition. That’s no longer enough.

As our Head of Finance you will build the entire finance function from zero. You will be the senior‑most finance person in the company, reporting directly to the founders, and you will own everything with a dollar sign attached to it — from the financial model and runway to the next fundraise, from the unit economics of a compute‑heavy AI business to payroll, accounting, and controls.

This is a true 0→1 mandate. You won’t inherit a team, a model, or a playbook — you will build them. You will move between boardroom‑level strategy and the operational plumbing in the same afternoon, and you will bring the financial rigor that lets us make sharp, fast decisions as we scale.

What You’ll Do

• Build the finance function from scratch: stand up FP&A, accounting, treasury, and controls. Choose the tools, design the processes, and decide what to keep in‑house vs. outsource — then run it.
• Own the financial model and FP&A: build and maintain the company model, budget, and forecast. Drive the annual and quarterly planning process, track actuals vs. plan, and turn variances into decisions.
• Master a compute‑heavy business: get deep on our unit economics — cost‑to‑serve, GPU/inference COGS, gross margin, and the levers behind them.
• Manage cash and runway: own cash flow forecasting, burn, and runway. Give the founders an always‑accurate picture of how much time and room we have to maneuver.
• Run accounting, close, and controls: own the monthly close, the books, and the relationship with outsourced accounting/tax partners — and build toward bringing the right pieces in‑house as we grow.
• Partner on the next raise: build the board and investor materials, own the data room and diligence, and be a trusted partner to the founders through fundraising and strategic decisions.
• Inform pricing and monetization: work with GTM and Product on pricing, packaging, and the economics of new offerings so growth and margin move together.
• Own the critical back‑office: payroll, benefits, equity and cap table management, tax, audit, insurance, and vendor/contract management.
• Build the team: as the function grows, hire and mentor the finance and accounting team behind you.

Who You Might Be a Good Fit If You

• Have 9+ years across strategic finance, FP&A, and/or accounting — including time at a high‑growth startup — and have either been the senior‑most finance person or a strong #2 ready to step up and own it.
• You have built things 0→1: a model, a planning process, or a finance function from a blank page, not just maintained someone else’s.
• You are an exceptional modeler who can move from a clean three‑statement model to a back‑of‑envelope answer in a Slack thread without losing rigor.
• You are equally comfortable with strategy and the operational plumbing — you will set the financial direction and also reconcile the books.
• You understand usage‑based / consumption business models and COGS‑heavy economics (bonus: AI, infrastructure, or compute).
• You are data‑literate — comfortable getting your own answers from the data (SQL or BI a strong plus) rather than waiting to be handed a report.
• You operate from first principles with high agency and low ego. You bias toward action, communicate proactively, and own outcomes end‑to‑end.
• You are SF‑based or willing to relocate to join our in‑person rhythm near Alamo Square.

Bonus If You Have

• Experience at an open‑source, developer‑tools, or creator‑tools company.
• Been a core finance partner through a fundraise (Seed → A → B).
• Carried early‑stage scrappiness alongside later‑stage rigor — you’ve seen both and know which to apply when.
• Used Comfy or have real familiarity with AI creative tools.

Compensation

Base salary: $200K–$300K

Equity: meaningful equity

Plus benefits and relocation support for SF.
