My LLC partner and I are needing additional capital for expansion. We would prefer not to borrow any cash for this right now. We both know someone who is willing to invest in the venture knowing there is a risk (like owning any stock would be). My partner and I would prefer that this investor not be an actual member of the LLC. Is there any way at all to accomplish this or must the investor be a member, knowing that this person can be specified in the operating agreement that they are a nonvoting and non-manager member? The LLC was formed in Delaware.
