Ventity is software for modeling dynamic systems. It combines a friendly, pretty interface with the power of modular entities, data-friendly architecture and dynamic model structure changes.

Some features & applications of Ventity:

  • Dynamic Structure

    In Ventity, you can introduce new entities on the fly during a simulation. You can introduce them via data, or programatically with discrete Actions. Introduce a firm into a market when you need it, or delete a cohort of products when they’re all sold. Simulate and review just your real behavior, without lots of clutter

  • Team Oriented Design

    Ventity’s modular model format allows for multiple people to work on different parts of a model at the same time. This video shows some of the opportunities for team model building in Ventity.

  • Interactive Charting

    You can pop up a chart on any variable in a diagram or list from a context menu. Charts feature smart scaling, brushing for values and legends, and drilldown, all a right-click away.

  • Introduction to Ventity – Projects & Reuse

    Our workshop from ISDC 2024 in Bergen is recorded below. This introduces modeling in Ventity, using a simple project model. It features the basic operations needed to build and run a model, as well as highlighting references and attributes, and reuse of structure an data.
