Which gets to my point, and for which a lawyer, as an emotionally uninvolved 3rd party can be far more valuable than as someone who merely knows the law: Decide what you want to get out of this: Do you want to destroy the company? Perhaps take them over/replace them in some way? (A good lawyer will ask "What does this accomplish", although deterrence is not illegitimate in my viewpoint). Get paid for your work, with suitable interest and penalties? Get a piece of the action of the other company? If you're telling the truth, there's a good chance you've got them in an exquisitely delicate situation. While they've officially raised a lot of money, if it just happened there it's unlikely it's all been transferred to their bank account. Even if so, you can mess them up going forwards with justified legal action. For those panicking over defamation, truth is an absolute defense to it, you just have to be able to afford to get your day in court. Although I'll note everyone who's every been in a lawsuit, on whatever side, says it becomes a consuming thing, you've got to think about the opportunity cost. Something a good lawyer will bring up.
