# Solutions: Endex + Rockhopper

Endex builds the model. Rockhopper owns the truth.

Endex delivers AI-native spreadsheet intelligence. Rockhopper delivers governance, control, and accountability that make it deployable in enterprise finance workflows.

## Endex domain

### Intelligence. Speed. Accuracy.

AI built for Excel to create, model, and research inside the workbook.

## Rockhopper domain

### Trust. Governance. Accountability.

Workflow assurance layer that verifies, routes, and governs every model change.

## Endex capabilities

#### Builds financial models in Excel

Generate three-statement models, DCFs, and LBO structures in minutes from natural language prompts.

### Data ingestion

#### PDF to table conversion

Eliminate manual data entry by moving statement and deck data directly into live Excel cells.

### Cited outputs

#### Deep research with verified sources

Use contextual workbook-aware research outputs with citations and attributed source links.

### Reference tracing

#### Trace cell references end-to-end

Follow labeled references across complex workbooks and jump to cited cells quickly.

## Rockhopper governance layer

### Cell attribution

#### Captures every cell Endex touched

Get cell-level attribution for all agent edits, plus timestamp and quantitative impact by change set.

### Approval routing

#### Routes material changes for approval

Changes above configured thresholds route to human approvers before committee distribution.

### SOX · IFRS

#### Enterprise audit trail

Every Endex and human action is immutable, attributed, timestamped, and exportable for auditors.

### Version control

#### Full version history with context

Every AI-produced version is retained with plain-English context and one-click restoration.

## Where Endex stops, Rockhopper starts

Endex is exceptional at intelligence. Intelligence is not governance. Rockhopper is the enterprise control system around AI-generated spreadsheet work.

### Endex: Undo changes

Revert unwanted changes in-session with minimal context.

### Rockhopper adds

Adds permanent version history, one-click restore to any historical point, and full rollback context.

### Endex: Auditable from start to finish

Citations attribute outputs to source data.

### Rockhopper adds

Adds cell-level model-change attribution, materiality logic, and SOX-grade approval trails.

### Endex: Firm templates

Reusable templates that autocomplete new input data.

### Rockhopper adds

Adds template governance from approved versions with inherited controls and version lineage.

### Endex: Enterprise security

Security certifications and enterprise retention agreements.

### Rockhopper adds

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

## The full workflow

From Endex prompt to controller sign-off in one governed flow. Fast because of Endex. Trustworthy because of Rockhopper.

1. **Step 1 · Endex**  
   **Analyst prompts Endex to build model**  
   "Build a three-statement model and DCF for Project Heron..." Endex ingests CIM data and builds workbook outputs in minutes.

```
   Project_Heron_Model.xlsx created. 847 cells populated across 6 tabs.
   ```

2. **Step 2 · Rockhopper**  
   **Rockhopper captures every cell Endex created**  
   Rockhopper logs assumptions, formula structures, and valuation drivers without requiring manual analyst documentation.

```
   847 cells captured. 12 key assumptions tagged. Version v1 indexed.
   ```

3. **Step 3 · Endex**  
   **MD requests downside scenario**  
   Endex applies stress assumptions and updates key valuation outcomes in seconds across affected workbook regions.

```
   94 cells updated. EV down $470M. IRR shifts from 14.2% to 9.8%.
   ```

4. **Step 4 · Rockhopper**  
   **Rockhopper routes material change for review**  
   Materiality threshold triggers approval routing and distribution pause until designated approver signs off.

```
   IRR delta flagged. Distribution paused. v2 snapshot locked pending approval.
   ```

5. **Step 5 · Human approver**  
   **MD reviews summary and approves**  
   Approver validates context and change impact quickly, then records decision in the same versioned workflow.

```
   v2 approved. Audit log closed. Deal committee distribution unlocked.
   ```

## Rockhopper's role in the Endex stack

Six things the agent produces. Six things only governance can hold.

01 — **Observability**  
   ### Every Endex action, visible  
   Cell-level attribution for every generated or revised model region, including quantitative impact context.

- Cell diff  
   - Impact calc  
   - Agent attribution

02 — **Control**  
   ### Human gates at thresholds  
   Material changes cannot be distributed without configured human approvals and segregation-of-duty checks.

- SOX controls  
   - Approval gates  
   - Deal-level config

03 — **Memory**  
   ### Version history Endex does not keep  
   Persistent cross-session timeline with one-click restore and comparison across any two historical versions.

- Permanent history  
   - One-click revert  
   - Deal timeline

04 — **Collaboration**  
   ### Faster human review of agent work  
   Condense large change sets into concise narratives and anchor review questions to exact cells.

- Change narrative  
   - Cell comments  
   - @mentions

05 — **Governance**  
   ### Audit trail for committees  
   Every agent action and human decision is immutable and export-ready for internal governance and LP requests.

- Immutable log  
   - IFRS · SOX  
   - LP exports

06 — **Source of truth**  
   ### One version always current  
   In multi-analyst, multi-agent deal workflows, Rockhopper surfaces authoritative version and full change context.

- Version pinning  
   - Live sync  
   - Team alignment

## Built and building

Parts of this stack are live today. Additional governance depth is being shipped as Endex + Rockhopper integration evolves.

### Live now

- **Cell-level change tracking for Excel**  
  Every Endex edit attributed, materiality-ranked, and retained with quantitative valuation impact context.

  Each model version gets plain-English summary and one-click rollback to prior state.

- **360 collaboration hub**  
  Cell-level comments, threaded by version, with @mentions attached to Endex-touched cells.

### Coming soon

- **Endex action capture and deal-level routing**  
  Model build and scenario events route to role-appropriate reviewers using deal-specific policies.
