What's the issue here? That Parker interned for Pincus directly, but not necessary for Zynga? Or that he's more well known for his role at Napster a year or two later? Or...?
Zynga was founded in 2007. If Parker is 38 now then he'd have been at high school 20 years ago, when Zynga didn't exist. It's a basic error anyone who did two seconds of fact checking on Wikipedia would have caught.
So this sentence makes the same point, but accurately, right?
"Just above them on the list in age is Sean Parker, now 38, who took up programming early and interned for Mark Pincus (later CEO of Zynga) while he was still in high school."
