Joe Lonsdale, co-founder of the unambiguously sinister data-mining startup Palantir and Clarium Capital alum, is just like the rest of us. When he turns 30, he rents out a castle. And when it's time to watch Game of Thrones, he procures a replica Iron Throne for himself.

Also in attendance at Lonsdale's viewing party—because who doesn't want to hang out with a guy who identifies with Joffrey?—were venture capitalist John Fogelsong, the Wall Street Journal's Evelyn Rusli, Square's Isabelle Bicaci, and someone in a viking helmet who has perhaps never watched Game of Thrones.
