Monstro is the operating system for governed financial intelligence. We build governance and intelligence infrastructure that enables artificial intelligence to operate safely, explainably, and at institutional scale.
We exist because the level of financial guidance historically available to a small group should be accessible to many more people. By combining AI with deep institutional infrastructure, we help financial institutions deliver more personalized, responsible, and life-changing financial support to millions of individuals.
We’re building mission-critical systems in a highly regulated domain, and we care deeply about doing it right. If you’re motivated by meaningful problems, high standards, and shaping infrastructure that improves financial outcomes, you’ll feel at home here.
About the RoleMonstro is hiring a hands-on SVP Head of Finance & Accounting to own the entire finance function: accounting, close, back-office operations, client billing, vendor cost management, reporting, and compliance.
As the founding finance hire, you'll build the finance function from the ground up - creating the infrastructure required to support Monstro's growth deliberately and ahead of the demand.
The scope is broad by design. This person keeps the books, runs close, and manages back-office operations - while simultaneously architecting the control systems that govern client revenue recognition, vendor and API cost attribution, and spend compliance in a regulated fintech environment. At Monstro, finance is operational infrastructure, not administrative support.
Why This Role MattersThis role exists to set a solid foundation for every financial and accounting transaction at Monstro. The primary objective is exhaustive, highly accurate, and scalable systems to manage spend - across every function, vendor, and client relationship.
Client billing is a major focus - revenue is usage-based, contracts are complex, and institutional clients require precision. Vendor cost management is equally critical, particularly API and data usage, which are variable, high-volume, and directly tied to product delivery. Monstro's internal controls must reflect the same standards as the banks and financial institutions we partner with - the reporting and compliance of that spend must be airtight.
Success is measured by the quality and integrity of the financial infrastructure this person builds - and how well it holds as Monstro scales.
What You’ll DoMonstro, Multi-Entity & International Finance
- Manage all things finance across Monstro's multi-entity structure, both in the US and globally as we scale
- Ensure revenue, contracts, and costs are correctly attributed across entities in line with multi-layered corporate structuring across IP, jurisdictions, tax, and corporate planning
- Own tax compliance and filing obligations across all active jurisdictions, including applicable benefits and credits
Client Billing & Revenue Recognition
- Own end-to-end client billing - usage data ingestion, invoice generation, collections, and revenue recognition
- Build billing infrastructure for B2B2C complexity: tiered pricing, usage-based models, per-user cost attribution, and institutional invoicing
- Partner with product and engineering to ensure usage data is accurate, reconciled, and traceable to the client and end-user level
Vendor Cost Management - API & Data
- Build a vendor cost management framework that tracks and attributes all API consumption, data licensing, and third-party infrastructure costs by product line, client, and environment
- Work with engineering to instrument cost attribution at the infrastructure level - spend should be traceable and verifiable, not estimated
- Surface cost trends, anomalies, and unit economics to support pricing, product, and executive decisions
Spend Reporting & Compliance
- Build the reporting layer that makes spend visible, attributable, and defensible - by client, product line, and cost category
- Build and enforce a spend compliance framework: policy documentation, approval chains, exception handling, and periodic review
- Serve as the primary point of accountability for financial controls, working with legal and external auditors as needed
Accounting & Back-Office Operations
- Own all day-to-day accounting: general ledger, AP/AR, payroll coordination, and month-end close
- Select and configure the accounting stack - ERP, expense management, and supporting tooling - built to scale
- Maintain audit-ready books and documentation from day one
Financial Reporting & Planning
- Build and maintain the core reporting package: P&L, cash flow, balance sheet, and cost-by-function on a monthly close cadence
- Develop operational reporting connecting financials to business performance - gross margin by product line, cost per unit of compute, billing efficiency
- Partner with leadership on budget-to-actual tracking, variance analysis, and financial modeling
- Clear, auditable picture of every dollar spent - by vendor, product, client, cost & category
- Client billing is accurate and fully traceable, with no disputes attributable to internal process failures
- API and data vendor costs are attributed at the user and client level, directly informing pricing and product decisions
- Multi-entity financials are clean, correctly attributed, and compliant across all active jurisdictions
- Monthly close completes on schedule with reporting leadership can act on immediately
- 12+ years of progressive finance and accounting experience, with at least 4-5 years in a senior leadership role such as Controller, VP Finance, or Head of Finance at a high-growth fintech or SaaS company
- CPA and Big 4 background are not required, but are strongly preferred
- Bachelor's in Accounting or Finance required, MBA or MAcc a plus
- Experience building financial infrastructure at a high-growth SaaS or fintech from scratch
- Hands-on experience with B2B2C or usage-based billing where cost attribution at the end-user level is a real operational challenge
- Familiarity with API economics, cloud infrastructure costs, and data licensing
- Understanding of multi-entity corporate structuring across IP, jurisdictions, tax, and corporate planning
- Strong command of GAAP, ASC 606, and documentation requirements in a regulated environment
- Experience implementing accounting and spend management systems (e.g., NetSuite, Sage Intacct, Airbase, Ramp)
- Calm, precise communicator across founders, institutional clients, and auditors
- Ownership & Impact: Shape the future of AI-powered finance—building a category-defining product used by consumers and institutions around the world.
- Elite Team: Join a team with leadership that has a track record of scaling companies from early stage to major exits.
- Principles-Driven Culture: Work in a culture that values speed, ownership, and impact—what most companies achieve in 90 days, we do in 45.
- Comprehensive Compensation Package: Competitive salary, equity, and robust benefits package, including paid health, vision, dental, and disability coverage.
