Earlier quoted context omitted.
Bump is known for their ingenious methods of relating lots of data to figure out which two phones were being bumped at the same time (there's a really cool answer on Quora about how they do it). I would assume this is their tech team figuring out how to apply the same techniques across two devices (browser/pc -> phone). I bet there is some really cool stuff at play here.

I think that may be the one I read.
