Can a syndicate enter another LLC as partner?

[Matt Lockwood]

My question here is, is it possible to raise private money and syndicate that money into a legal entity that would then join as a member of a separate LLC for the purpose of contributing capital to fund new construction? To me (unless the members have a role) this seems like it meets most or all of the criteria to be considered a security to those members of the original syndication of funds. Has anyone done this or something similar and is willing to share experience? My goal here is to figure out how I can pursue private money investors and be able to put that money to work and earn my investors a handsome return while maintaining control of the LLC for my construction projects. Seems like the only way to do this would be to make it more of a loan from these private investors.
