There are a few people in tech who resemble each other so closely, they'd make you do a double take.
For a while, these pairs were documented on a popular Tumblr, Tech Look-Alikes.
From investor Mo Koyfman and Sean Parker to Drew Houston and Elon Musk, here are the men who not only share similarly successful tech careers, but they also share similar facial features.
(For simplicity's sake, we only compared men in this list. If we missed any pairs, let us know in the comments.)Kiva.org CEO Matt Flannery looks like Appspavy founder Chris Cunningham.
Tumblr's David Karp has the same light eyes and messy mop-top hair as Artsy's Carter Cleveland.
Billionaires Elon Musk of Tesla and Drew Houston of Dropbox could make you do a double take.
Mark Zuckerberg's tech doppleganger lives in Dublin. He's Paddy Cosgrave, founder of Web Summit and F.ounders. Even their "F" logos look similar.
Billionaire Sean Parker even wears the same kind of glasses as Spark Capital's Mo Koyfman.
I Can Haz Cheesburger founder Ben Huh and Mixpanel's Spencer Chen love the same kind of glasses.
Mashable's Pete Cashmore and Shelby.tv's Reece Pacheco have almost the same amount of scruff.
Bonus: PolicyMic founder Chris Altchek resembles actor James Marsden
Bonus: Quora co-founder Charlie Cheever looks like the product of actors Josh Hartnett and Michael C. Hall (Dexter).
Bonus: It's impressive that tech influencer Robert Scoble and actor Philip Seymour Hoffman share the same hair shade. They no longer have the same glasses (Scoble wears Glass now).
Bonus: There's something about Techmeme founder Gabe Rivera that reminds us of Hills reality star Brody Jenner.
Bonus: Obama and Infor CEO Charles Phillips have the same beaming smile.
