Head of Finance

Comfy•San Francisco, CA

1d•$200,000 - $300,000•Onsite

About The Position

Comfy is seeking its first Head of Finance to build the entire finance function from the ground up. As the senior-most finance person, reporting directly to the founders, you will own all financial aspects of the company, including financial modeling, runway management, fundraising, unit economics for a compute-heavy AI business, payroll, accounting, and controls. This is a 0→1 role where you will establish the finance function, including building the team, models, and processes. You will balance strategic, boardroom-level discussions with operational tasks, bringing financial rigor to support rapid decision-making and company scaling. Every dollar deployed effectively will contribute to Comfy's growth trajectory.

Requirements

9+ years across strategic finance, FP&A, and/or accounting, including time at a high-growth startup.
Experience as the senior-most finance person or a strong #2 ready to step up and own it.
Proven ability to build things 0→1: a model, a planning process, or a finance function from a blank page.
Exceptional modeling skills, capable of moving from a detailed three-statement model to quick back-of-envelope calculations.
Comfort with both strategy and operational plumbing, from setting financial direction to reconciling books.
Understanding of usage-based/consumption business models and COGS-heavy economics (bonus: AI, infrastructure, or compute).
Data-literate, comfortable extracting own answers from data (SQL or BI a strong plus).
Operates from first principles with high agency and low ego, biases toward action, communicates proactively, and owns outcomes end-to-end.
SF-based or willing to relocate to join our in-person rhythm near Alamo Square.

Nice To Haves

Experience at an open-source, developer-tools, or creator-tools company.
Core finance partner experience through a fundraise (Seed → A → B).
Ability to balance early-stage scrappiness with later-stage rigor.
Used Comfy or have real familiarity with AI creative tools.

Responsibilities

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. Be the person who knows exactly how a usage-based AI business makes (and loses) money.
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 — the unglamorous things that have to be exactly right.
Build the team: As the function grows, hire and mentor the finance and accounting team behind you.
