Director, Finance at Spellbook

Job description

Spellbook is the most comprehensive AI copilot for transactional lawyers. It works directly inside Microsoft Word to help legal teams draft, review, and negotiate contracts up to 10x faster and with greater precision. Today, more than 4,000 law firms, in-house teams, and solo practitioners rely on Spellbook to simplify their workflows and eliminate the drudgery of everyday contract work. We are backed by leading investors including Khosla Ventures, Thomson Reuters Ventures, Inovia Capital, The LegalTech Fund, Bling Capital, and Moxxie Ventures. The company recently raised $50 million in Series B funding, led by Keith Rabois at Khosla Ventures, bringing its total funding to more than $80 million. *This is an existing vacancy ABOUT THE ROLE We’re looking for a Director of Finance to help shape Spellbook’s next stage of growth. You will work closely with our VP of Finance, executive team, and leaders across the company to translate strategy into financial plans, guide our most important investment decisions, and create a clear view of business performance. This role sits at the intersection of finance, strategy, and company execution. As the company scales, you will build the capabilities, processes, and operating cadence to develop insight into the drivers of our business and bring analytical rigor to decisions across growth, product investment, organizational capacity, and capital allocation. We’re looking for a business-oriented finance leader who can move comfortably between the details and the bigger picture. You should be equally capable of building a rigorous model, challenging assumptions, building board-level presentations, and helping an executive decide what action to take. RESPONSIBILITIES Build investment cases for major strategic bets, new segments, market entry, GTM and product investments, and lead post-investment reviews to assess expected versus realized returns. Own the framework for allocating spend and headcount across GTM, R&D, and G&A, including the mechanisms and decision criteria for reallocating resources as priorities change. Own the annual planning, quarterly forecasting, and rolling outlook processes, establishing clear inputs, owners, timelines, and accountability for forecast accuracy. Make unit economics legible to non-finance leaders, including gross margin and model/inference costs, cost-to-serve, CAC payback, customer profitability, and NRR/GRR, so teams can understand the economics of their decisions and run their own math between reviews. Partner with GTM and Product on pricing and packaging as the model evolves, including usage-based components. Model alternatives, stress-test downside scenarios, and establish clear economic guardrails for commercial decisions. Work with the finance team to shape our systems roadmap: CRM, billing, ERP, expense, and reporting. Set priorities, define requirements, and drive implementation with RevOps, Data, and external partners, with clear ownership for data integrity and reporting accuracy. Partner with the VP Finance and executive team on board and investor materials, translating company performance, forecast changes, and strategic decisions into a clear financial narrative. Build the capabilities, processes, and operating cadence required for a high-performing strategic finance function, including developing the team and establishing clear ownership across planning, forecasting, analytics, and business partnering. QUALIFICATIONS What you've done: Run planning, forecasting, and business partnering at a high-growth B2B software company, ideally through a phase where the model or motion changed underneath you. Worked inside a usage-based, consumption, or hybrid pricing model, or built the transition to one. You know why consumption forecasting is different, and you have been wrong at it before and learned something. Owned or led a meaningful finance systems or process change, and can talk specifically about what you scoped, what you deferred, and what broke. T
