I read this and still have no clue what this business is. You may want to consider the possibility that Silicon Valley isn't massively broken and you simply don't have a good elevator pitch.
I understood but only because I work very near the world of PR, which is the language in which the parent post was written.
The background is that big companies like Coke or Nike need creative content to post on Facebook and Twitter. They pay PR agencies huge dollars to come up with that content.
My plain English translation would be something like: this company helps PR agencies make custom online games for their clients. The agencies will look good because lots of people will play the games. (Maybe the games also collect consumer preference data--not clear.) Agencies with developers on staff can self-service; agencies without developers can pay extra to get help.
