Claude + Rockhopper | AI Finance Stack

Claude builds the model. Rockhopper audits it.

Claude generates the model. Rockhopper governs. Model-building and independent audit, working as one - the AI finance stack your organization can actually trust.

Claude Domain

Intelligence. Analysis. Generation.

Rockhopper Domain

Trust. Control. Accountability.

The new bottleneck

Reviewing models was hard before. Now, it feels impossible.

Your team moves fast with AI agents — Copilot, Claude, custom analysts. But fast shouldn't mean unaudited. Every model that reaches a CFO needs an independent reviewer who actually understands the math.

"Did you check the Q4 model the agent built?"

"Which one? It's shipped 14 versions today."

The governance and audit layer

Let Claude build the model. Rockhopper proves it can be trusted.

An independent audit layer for every change an AI agent makes inside Excel and Google Sheets.

Cell attribution

Every cell Claude touches, attributed.

Cell-level attribution for every agent edit — with timestamp and quantitative impact, grouped by change set.

Approval routing

Material changes wait for a human.

Changes above the thresholds you set route to named approvers before anything reaches committee.

SOX · IFRS

Enterprise audit trail

Built for the auditor's questions.

Every action, AI or human — immutable, attributed, timestamped, and exportable on request.

Version control

Every version, with the why.

Each AI-produced version retained and one-click restore.

The full workflow

From Claude prompt to controller sign-off in one governed flow.

Fast because of Claude. Trustworthy because of Rockhopper.

Claude · Rockhopper · Human reviewer

  1. Step 1 · Claude

Claude executes the instruction

Prompt: update the revenue model from the Q4 memo, revise EBITDA, and check covenant headroom against the credit-agreement terms in the Debt tab. Claude applies the changes across the pricing, volume, EBITDA, and debt tabs.

FY26_Revenue_Model.xlsx updated · 47 cells across 4 tabs

  1. Step 2 · Rockhopper

Rockhopper captures and classifies

Every changed cell is logged by type — structural or input — with quantitative impact and a reviewer-ready summary.

47 changes · 15 structural · 32 input · EBITDA −$11.4M · net leverage 3.1x → 3.4x (covenant 3.5x)

  1. Step 3 · Rockhopper

Rockhopper surfaces what to review

Rockhopper highlights the changes worth a look — structural edits, material impacts, and the covenant flag — then offers routing options. The preparer chooses to send the review to their manager by email via MCP, with the spreadsheet and full change context attached.

Routed via MCP · email to controller with spreadsheet + change context attached

  1. Step 4 · Human reviewer

Controller reviews and approves

The controller opens the spreadsheet, reads the comments the preparer left, reviews the context behind each change, and approves the version.

Version approved by controller · preparer comments and change context retained

  1. Step 5 · Rockhopper

Version locked, audit complete

The approved version is locked, an immutable snapshot is created, and the full agent + human decision trail is stored.

Rockhopper's role in the Claude Excel stack

Six conditions that make AI deployment possible in enterprise finance.

01 — Observability

See everything agent touched

Cell-level visibility into what changed, by how much, and what it means before human sign-off.

Cell diff Impact calc Agent attribution

02 — Trust

Human control at thresholds

Materiality gates and approval workflows apply to every contributor, including agents.

SOX controls Approval gates Distribution locks

03 — Reversion

Undo agent actions instantly

Every version retained indefinitely with one-click rollback and context of what is being restored.

Version history One-click revert Forever retained

04 — Collaboration

Faster human review

Review concise change narrative and thread questions directly where agent edits occurred.

Change summary @mentions Threaded review

05 — Governance

Enterprise-grade audit trail

Immutable logs combine every agent action and human decision into export-ready evidence.

06 — Source of truth

One version everyone trusts

Version pinning and context-aware sync keep controllers, FP&A, and leadership on same state.

Where Claude stops, Rockhopper starts.

Claude is exceptional at intelligence. Intelligence is not governance. Rockhopper is the control system around every spreadsheet an AI touches.

Claude · Cell-level citations

Explains every calculation with citations to the exact cells.

Rockhopper adds

Cell-level attribution of every model change, materiality logic, and SOX-grade approval trails.

Claude · Review before apply

Highlights and explains each edit; nothing is saved until you approve.

Rockhopper adds

Permanent version history, one-click restore to any point in time, and full rollback context.

Claude · Reusable skills

Save a workflow once; the team runs it as a one-click skill.

Rockhopper adds

Governance over those skills — approved versions only, inherited controls, and version lineage.

Claude · Enterprise deployment

Runs inside your compliance setup via Bedrock, Vertex AI, or Foundry.

Rockhopper adds

Workflow governance: segregation of duties, thresholds, approval routing, and sign-off logging.
