Commercial, Government, Consulting Use
Ventana Systems is proud to support education with tens of thousands of free PLE downloads every year.
However … we need the support of non-educational users to sustain our Vensim development efforts. Therefore we ask that commercial and government users purchase an inexpensive license for uses other than software evaluation. This requirement includes any research that lacks an educational component or is proprietary or classified. If there’s any doubt, please consult section 7 of the Vensim license.
The Vensim Model Reader may be distributed for free with your models (including commercial use).
