In Open Innovation, companies open up their innovation activities to external stakeholders. Using web-based ideation platforms (WBIP), companies crowdsource ideas for innovations from their customers. Ideation can be considered as a create process. Therefore, in this research we analyze how current web-based ideation platforms run by firms support Shneiderman’s GENEX framework that aims at supporting creativity in information systems. By doing so, we were able to identify the state-of-the-art in practice as well as further research areas. We analyzed 16 web-based ideation platforms in total. Results indicate that current WBIP use creativity tasks different intensive and that some GENEX tasks are already well implemented, while others require further research. Results are discussed and theoretical and practical contributions, limitations and identified research questions provided.
