A bit misleading this part:
Less than four months after launch, Quip now runs on 76% of the world's smartphones and tablets.<p>I didn't know I had Quip on any of my devices.<p>Also:
Available in 11 languages on 8,560 distinct mobile devices, Quip can now be used by 1.3 billion people on mobile devices, and over 2 billion people on PCs.<p>Last time I checked there were only about 1.5 billion PCs in the World.<p>I do like the website, but I'd be a bit spooked by the big numbers.
