Actually Qlik as a plataform isn't the only deciding where be present. The partners an resellers take it for new customers and industry, it is in practically all areas in all industry and kinds of organisations (Like ONU, Med Air and others...), so if you want to make that kind of question you don't have to ask simply do Qlik where they focus, but to all partner network, that is aprox. a few hundreds of companies in dozens of countries... Its like asking to oracle where they want to focus Oracle DB , it is a abstract product* that can be moulded to the specific needs of each company.
