Who presented this offer? Who are you demoing this to? I'm not asking for names here, just the nature of the entity: is it a sole practitioner legal representative, or is it a larger firm of some sort? Are they reputable? Is your technology or product sexy enough that it'd even warrant anonymous money in the first place? IANAL (or even remotely an expert on this subject for that matter), but one would think reputable anonymous money would just use reputable firms as a conduit to avoid exactly this scenario. Also if it's organized crime you're worried about, favorable terms right now absolutely do not matter. They have a long history of investing in businesses, only to later use that investment as leverage to systematically milk the business for all its assets. Your terms now are only worth as much as your ability to resist agreeing to unfavorable terms at a later time under potentially extreme duress. I don't know if that's what's happening here (it probably isn't), but keep in mind that anonymous could also mean competing interests trying to tamper with your business in a legal manner, or any number of other bad-news scenarios. If it's too good to be true, it probably is. Anonymous or not, personally I'd only touch money that you're able to verify as being highly reputable. Anything less isn't worth the potential hell that could ensue.
