When Northeastern University alumnus Charles Svirk and his best friend Matthew Valich, a graduate of Emerson College, released Photos to Photos in the App Store in mid-July, they warned potential users:

If Apples to Apples and Cards Against Humanity had a baby, this would be their wild child.

With a description like that, it’s no surprise the new mobile game attracted so much attention the duo’s server crashed. “It’s a good problem to have,” admitted Svirk, adding that they have since signed on a chief technology officer to help handle the app’s complexity and growing popularity.

Photos to Photos is a free, social game of photo comparisons that transpired at the beginning of 2013. Svirk and Valich were playing Apples to Apples over winter break and had this sort of aha moment. The physical product didn’t have a mobile component, yet their mobile devices held an overwhelming amount of user-generated content — all sitting stagnant, just waiting to be incorporated into some wildly addicting game.
