No endless meetings here – if it can be done today, we're all about getting it done today.

About the role

We're looking for a Head of Finance who has been here before — not at a Fortune 500, but at a fast-moving, high-growth startup navigating the messy, exciting stretch from $10M to $100M ARR. You've built the financial infrastructure that lets a company scale without losing control. You've sat in the room when hard decisions were made and given leadership the data to make them confidently. This is not a bookkeeping or reporting role. This is a company-building role. You will own financial strategy, planning, and operations as we scale from where we are today to a company ready for a major liquidity event.

What You'll Own

Financial Strategy & Planning

• Own the company's financial model, annual plan, and multi-year outlook
• Drive the FP&A function — forecasting, scenario modeling, and board-level financial reporting
• Partner with the CEO and leadership team on strategic decisions: pricing, unit economics, resource allocation, and growth investments
• Build and maintain a real-time pulse on the business through dashboards and KPIs that actually get used

Revenue & Business Finance

• Own ARR tracking, cohort analysis, and SaaS metrics (NRR, CAC, LTV, payback period)
• Partner with Sales and Customer Success on deal structuring, pricing strategy, and revenue recognition
• Build the infrastructure to understand where we make money and where we don't

Capital & Investor Relations

• Prepare materials and data packages for investors, board meetings, and future fundraising processes
• Manage relationships with existing investors and support due diligence processes as needed
• Own cash management and runway visibility at all times

Accounting, Compliance & Controls

• Oversee accounting operations and ensure GAAP-compliant financials
• Own audit readiness and manage relationships with external auditors and tax advisors
• Build scalable internal controls and financial processes that won't break as we grow

Team & Infrastructure

• Build and lead a lean, high-output finance team
• Own the finance tech stack: ERP, billing, expense management, and reporting tools

What We're Looking For( We’re open to candidates who don’t check every box but show strong potential.)

• Bachelor’s, Master’s degree or MBA from a top-tier academic institution (e.g., Ivy League, Oxbridge, top global business/engineering schools)
• 8+ years in finance, with meaningful experience at a high-growth B2B SaaS or marketplace company
• Proven track record of scaling a company from the $10M–$100M ARR range — you know what breaks at each stage and how to get ahead of it
• Deep fluency in SaaS metrics and business model economics
• Strong financial modeling skills — you build models that drive decisions, not just decks
• Experience managing accounting operations and working with external auditors
• Exposure to fundraising, investor relations, or M&A processes
• High ownership mentality — you run toward ambiguity, not away from it

Nice to Have

• Experience preparing for or navigating a Series B/C fundraise or pre-IPO readiness
• Background in investment banking, venture-backed startups, or high-growth SaaS
• Familiarity with ad tech, marketplace, or e-commerce business models
• CPA or MBA (preferred, not required)

What We Value

At Topsort, we seek professionals who embody the following qualities to drive our mission forward:

• Deep dive into details: Professionals who are not content with superficial answers and dive deeply into the details to uncover root causes and optimal solutions.
• Team first: A low need for individual recognition, always prioritizing collective results over personal credit.
• You thrive with ambiguity: Exceptional ability to tackle open-ended problems in unstructured environments, turning chaos into structured innovation.
• Adaptability: Willingness to learn, mentor, lead, and follow as the situation demands, fostering growth at all levels.
• Urgency: A disproportionate sense of urgency in execution, while keeping scalability and the creation of replicable processes in mind to ensure long-term success.
• Curiosity: Genuinely curious individuals who can quickly learn difficult concepts and apply them effectively.
