No? From what I can see they've taken less than a 10th of that in VC. And this is the first time in over a year that I've heard anything about them. Buzz isn't everything, and maybe there was a viable business there. But they certainly weren't setting the world on fire.
It's pretty hard to see how a near $100 million exit in circumstances like that would be disappointing or "really cheap". (And congrats certainly seem in order for everyone involved).
That's great to hear. But since pretty much nobody here has access to those awespme internals, I still don't see where the gp's "really cheap" impression would be coming from.
When you have used the technology and seen with your own eyes the amount of time and effort it saves you when developing a mobile app, $85M really seems very cheap, especially when you compare it to how much they paid for an Instagram for example. Plus it should be mentioned that although their primary focus was on mobile platform, their SDK's also support Windows desktop, MacOSX, and traditional web dev. The potential is absolutely huge.
