All you have to do is go to the state where they registered and look them up on the state business registration. All of the information is public domain, even LLC's. You only need the registered business name, or address, or individuals who filed/etc. There's even some websites out there which will look through all available states.
Kingdragon doesn't "secure" this information. When you become a Corp, all signees/trustees go on public record. He, and anyone working for the LLC, are required by law to provide the full disclosure when requested by an interested party.
I've been on the board of 3 Full Corporations and 1 LLC, and a part of numerous private ownership and similar businesses.
