I want to start a crowdfunding website where people can raise money for whatever cause they seem important, including legislation. What type of company should I file this as? I am not concerned about making a living from this. Would this qualify for a 501c3 since the lobbying is executed by a member of the website? What if these funds constitute less than 20% of expenditures? Should this become a 501c4 instead so there is no limit on lobbying? What about a benefit corporation or a flexible purpose corporation? I want to start this company out as small as possible and in California, so what would the requirements be for things such as the board of directors, if it is required at all (for the benefit corp. and flexible purpose corp.)?
