Tl;dr: the sexting app. I met one of the cofounders at the Stripe CTF meetup. They're a Waterloo U. Team, seemed like a sharp group. Pair was their pivot. Initially they had a 3D mouse based on the iPhone accelerometers.

Going from a 3D mouse to Pair seems like more than a pivot. It's more like a back handspring or some larger acrobatic maneuver.

Someone should compile a list of initial ideas vs pivots. It would be interesting to see how many groups had pivots this drastic.

Haha, what can we say, we're just that flexible. ;)
