Iterate, validate and share financial models faster than any spreadsheet
NUMERUS is an AI-powered workspace for finance professionals designed to make you productive.
Trusted by industry leaders
Agents turn ideas into models
Accelerate model crafting by handing off repetitive tasks to agents — like building LBOs from term sheet or balancing 3-statement while you focus on decision making.
Numerus has transformed how I build and track my financial models daily. Multiple agents tackle my workspaces simultaneously, slashing build time by 50%. Can't imagine modeling without it. Setup was effortless!

NUMERUS
The Cursor for finance — a purpose-built IDE for financial modeling
NUMERUS is a purpose-built IDE for financial modeling. Where Cursor gave software engineers an AI-native coding environment, NUMERUS gives finance professionals an AI-native modeling environment — built from scratch around the .num DSL, not bolted onto Excel.
Four Pillars
IDE Experience
A familiar spreadsheet-like canvas with the power of a developer environment underneath. Syntax highlighting, formula intelligence, and error detection built into the editing experience. Designed for keyboard-first power users — FP&A analysts, CFOs, and finance teams.
.num DSL & File Format
A proprietary domain-specific language designed exclusively for financial modeling — the first of its kind. Native primitives for time periods, fiscal years, typed values, named scenarios, and explicit dependency graphs. Files are human-readable, text-based, and diffable.
Version Control & Collaboration
Git-style version control as a native feature, not a plugin. Full audit trail on every assumption change. Real-time collaboration enabled by the text-based .num format. No more emailing files or _FINAL_v2_USE_THIS.
AI Copilot
AI that understands financial model structure and business logic — not just formula syntax. Trained on the .num DSL: suggests, completes, audits, and explains. Can generate entire model sections from natural language prompts. Understands context across revenue models, cost models, and cap tables.
Frequently Asked Questions
- What is NUMERUS?
- NUMERUS is a purpose-built IDE for financial modeling — the Cursor for finance. It is built from scratch around the .num DSL, a proprietary domain-specific language designed exclusively for financial modeling. It combines a spreadsheet-like IDE, git-style version control, real-time collaboration, and an AI copilot that understands financial model structure.
- How is NUMERUS different from Excel or Google Sheets?
- Excel is a general-purpose grid. NUMERUS is a purpose-built financial modeling IDE with its own domain-specific language (.num), native version control, real-time collaboration, and an AI copilot that understands financial logic. Different category entirely.
- How does NUMERUS compare to Pigment, Mosaic, or other FP&A tools?
- Those are planning tools, not modeling environments. NUMERUS is an IDE built around a proprietary DSL with native primitives for financial modeling — time periods, fiscal years, typed values, scenarios, and dependency graphs. The architecture is fundamentally different.
- How does NUMERUS compare to Cursor?
- Cursor is the closest analogy in spirit — both are AI-native IDEs purpose-built for their domain. Cursor is for software engineering, NUMERUS is for financial modeling. Different domain, same philosophy.
- What is the .num file format?
- The .num format is a human-readable, text-based, diffable file format for financial models. It is powered by the NUMERUS DSL which has native primitives for time periods, fiscal years, typed values, named scenarios, and explicit dependency graphs.
- How do I get started?
- NUMERUS is in MVP stage. Sign up at app.numerus.one or request a demo at /demo. The team is looking for design partners and early adopters to co-build the product.
- Does it replace a CFO or finance team?
- NUMERUS is a financial modeling environment and co-pilot — not a replacement for experienced finance leadership. It gives you the IDE, version control, and AI assistance to build and iterate on models faster, especially before you can afford a full-time CFO.
- Is my data secure?
- Financial data is encrypted end-to-end, stored securely, and never shared with third parties. Industry best practices for data protection and compliance.
