Kickstarter does not allow product design campaigns that don't have any physical products and also no rewards in mass quantities. Indiegogo is less strict.
>>>
Projects cannot offer rewards in bulk quantities (more than 10).
<<<
>>>
No product simulations or photorealistic renderings
Technical drawings, CAD designs, sketches, and other parts of the design process are awesome and encouraged. Photorealistic renderings and simulations that could be mistaken for finished products or real events, however, are not allowed.
