Within the open innovation debate, significant attention has been
paid to the fact that customers can be a useful source for bringing
new ideas and concepts into a company. In this context, online
platforms have become a widely used instrument to facilitate
interaction between companies and customers. While prior
literature discusses various aspects of open innovation platforms,
a market-oriented analysis covering all types of platforms for idea
creation and concept development seems to be still missing. By
evaluating a total of 44 different innovation platforms, we identify
the degree of interrelation between five major platform attributes
and develop two key differentiating dimensions: The platform
operator (company vs. third party) and the platform purpose (find
solutions vs. understand customers). The resulting classification
matrix highlights a newly emerging category of online open
innovation platforms, opening the field for deeper investigation in
future research.
