About Bridge Town

Financial planning that
speaks your language

Bridge Town replaces proprietary tools like Anaplan and Pigment with an AI-native, code-first approach. FP&A analysts describe business logic in plain English — we handle the Python, the version control, and the collaboration.

What we're building

A platform where financial models are code — readable, testable, and version-controlled.

AI-native modelling

Describe your budget, forecast, or variance analysis in natural language. Bridge Town writes the Python, connects the data, and runs the model.

Version control built-in

Every model has a complete, versioned project history. Branch, diff, merge, and roll back — the same discipline that made software engineering reliable, applied to financial models.

Real collaboration

Review model changes like code changes. Impact diffs show exactly how a proposed change affects your forecast before you merge.

Google Sheets integration

Connect your existing Sheets as data sources. Drivers, actuals, and assumptions flow directly into your models without manual exports.

Interactive dashboards

Models produce Plotly dashboards automatically. Share a link — stakeholders get a live view without touching a spreadsheet.

MCP-first interface

Bridge Town is built around the Model Context Protocol. Use it via Claude Desktop, Claude Code, or any MCP-compatible AI client.

Our principles

The decisions behind how we build.

  • 1

    Open standards over proprietary lock-in

    Your models are plain Python. Your data pipeline runs on open tools. You own your work — export it, run it locally, or move on without a migration fee.

  • 2

    Reproducibility is non-negotiable

    Re-running a model at a past commit against the same snapshot produces the same output. That is the foundation of trustworthy financial reporting.

  • 3

    AI is the interface, not the gimmick

    We use Claude to translate analyst intent into well-structured, testable Python models. The AI is useful because the underlying platform is solid — not the other way around.

Why we built this

Read the docs

  • Anaplan costs too much

    Enterprise FP&A tools charge six figures for features that add complexity without adding value. Bridge Town does more for a fraction of the cost.

  • Spreadsheets do not scale

    Version control, peer review, and automated testing exist in every other field of knowledge work. FP&A deserves the same infrastructure.

  • Analysts should not need to learn proprietary languages

    Pigment and Anaplan have their own formula languages that go nowhere. We use Python — the most widely-used language in data work — so analysts build transferable skills.
