Worry about making users happy. Competitors are a second order problem.
A request to abide by the NDA is about all you can do, and in our case it wasn't really ever going to make a difference.
Thank you for replying, I'm honored that you've read my note and taken the time.
I am having trouble understanding this. Isn't "why" trivial, if not obvious? I think "what" and "how" are far more important than "why".
In my last company, we once were "probed" and our books were opened up, I am guessing to see "where we were at".
Maybe your situation was a probe, maybe an acquisition gone bad - but I wouldn't sweat it too much. Your already steps ahead if they even did try and copy you. Your a startup, your a survivor, and just keep trucking on.
Frustrating and emotional I know. You had your hopes up, and the acquisition didn't go through, but take it as a learning experience and use it as motivation to keep kicking ass.
Best of luck.
I presume you're waiting for your lawyers to call you back, because this is why you have lawyers in the first place. You might as well sit down with your accountants and start trying to quantify the gap between your best and worst-case scenarios in order to get a handle on your economic loss and establish what the efficient settlement price is. I'm only a law student so I can't give you any real guidance, other than to avoid becoming emotionally invested in who's right or wrong.
PS: they might sue you anyway, if the economics makes sense. It's not unheard of.
