16 David Hammer
Hammer chose Google over Facebook upon graduation, writing a prescient essay about building a Facebook platform to secure his Google gig. After six years as a product manager, he left to found SpotCouncil, a site for expert networks.
“We did problem sets together our sophomore spring, as Facebook was taking off,” Hammer said. “I have vivid memories of hanging out with Mark and Kang-Xing in a dorm basement, looking at Facebook’s usage stats as they went through the roof and being pretty excited about it.”
