Petriflow was originally created in 2008 to teach students business process management and process driven application development. Several releases of Petriflow modeler and Petriflow engine implemented by founders of NETGRIF enabled hundreds of students to apply theory of Petri nets, workflow processes, and case management in agile development of different use cases inspired by real world systems. We were fascinated by the speed of the learning curve of the students and by the overall time during which they were able to build applications by deploying the Petriflow processes. After we have shown some of our PoC applications implemented in Petriflow modeler and deployed in Petriflow engine to people from industry, the positive feedback motivated us to implement the first commercial version of Petriflow modeler and Petriflow engine and to found NETGRIF company.
