  • 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

  • Vensim Model Import

    One of the newer features of our recent releases is the Vensim Model Import tool, and we’d like to take a few moments to walk through some of its uses and some tips for importing models from Vensim to Ventity. The first thing to keep in mind is that importing a Vensim model can only

  • Data Science meets the bottom line

    Ventity can be used to put big data in context, by incorporating the learnings from big data in simulations that account for organizational structure and finances. Ventity can also do data intensive simulation, with an architecture friendly to relational data and dynamically changing lists, optimization for calibration, and much more  on the road map.
