Everyone is not open to being aquired by Facebook until they get a $10B offer. Even if they say no now, that’s no guarantee for the future.
Thanks to my previous company's acquisition, we are financially set. More money at this point won't mean much to us. Instead, being able to have a positive impact on the world is what really drives us. Hopefully, this is visible from what we've written, and what we've built (there are no growth-hack-y, spam-your-friends "features" in our app). And in the coming months, we'll continue to expand on this vision in our product. We hope you'll use the product so you can see this for yourself.
