On the Blender Network we really want that everybody is recognizable and uses real names and pictures.
Companies, such as studios, schools, and the like, have obviously particular requirements in terms of naming and appearance, therefore corporate accounts have higher flexibility. Since we expect corporations to have a stronger financial position than other members, we have decided to differentiate the subscription fee, so to make the service accessible also to freelancers and non-for-profit organizations.
Corporate accounts are thought for studios, multi-person ventures, but also for one-person enterprises. In this last case, however, you can opt for a freelance subscription following all related guidelines and additionally mentioning in your description that you own/founded/run your personal company.
