Overview of River features
This short video highlights the key features. You'll find more details below.
Model validation and traceability
Visual model design
River uses visual design techniques to enable intuitive structuring, validation and handover of models.
- Interactive model map letting you design and navigate your model visually: no more separate. documentation or getting lost in cell references.
- Intuitive explanation for each operation, to validate end-to-end logic.
- Visual indicators to spot areas in the model that need attention.
Risk management
Automated error prevention
Error prevention is built at the core of River. Decades of observation of typical errors allow us to prevent most user mistakes and build more safety into the models.
- User-friendly configuration: no tedious formulas.
- Configuration errors clearly explained: no more #VALUE! that you don't understand.
- Automated data quality checks: surface issues such as data loss or out-of-bounds variables.
- The risk dashboard indicates all model areas that could use more checks (coming soon).


Privacy first
Privacy is a must in critical models in consulting, investment and finance, for instance. We can't afford any sensitive data to leak out.
- Desktop-only application: the River application runs only locally, no cloud service is necessary to run it.
- Local files: the model's logic and data is saved in the Excel workbook, so that you can completely control how to share it.
- No data exchange: no input, output or intermediary data is ever sent out of your computer
Modeler productivity
Integrated in Excel
Professional modelers need to build fast. River integrates a powerful model designer and calculation engine right in Excel, where you need it.
- Keep using Excel: all features available within Excel from the toolbar.
- Model saved in the Excel workbook: model and data are saved in the Excel file, easy to share.
- Use data in the Excel workbook: just paste data in the workbook and use it in the model.
- Visualize all model data in Excel: full transparency with the click of a button.
- Dynamic updates: River calculations update automatically when inputs change.

Business-focused components
Business models constantly recreate the wheel, so we have integrated the most common features built by our users, and the list keeps growing:
- Assumption management: automatically manage sets of values that you want to test.
- Scenario management: combine assumptions into scenarios, toggle between them to inspect results, or generate multi-scenario outputs for comparison.
- Forecast horizon: extend historical data with future years, and manage base year automatically.
Advanced features
High performance
River embeds its own calculation engine, which bypasses Excel's data size limitations.
- Unlimited data size: River can ingest and process more than Excel's 1-million row data tables.
- Scalable performance: River processes data as tables, making it much more efficient for large data volumes and complex calculations.
