Disclaimer: I don't know anything about anything. >my company is in public beta and haven't even launched yet! Buy low, sell high. You don't approach this early for no reason. >they specifically said that their senior M&A team and C-level execs have been thinking about building a product similar to ours That was meant to scare you. Ironically, if you're smart, it achieves the opposite. "Ok, so why don't you? What does a 6-man startup have that a global player doesn't?" My tentative vote, pending further information: Nay. From your thread comments, you seem psyched about the product - see how far that enthusiasm can push your product before you risk losing it. When you're enthusiastic, you want to "control your own destiny," as they say in college football. Also, beware "best case scenario" bias. If it were me, I would promise you creative control, teams on top of teams beneath you, fair captain. But where do you see that. Google acqui-kills 100 companies a year.
