The three founders of Weebly have come a long way since their apartment at Penn State nearly ten years ago. Since starting a website-hosting service, David Rusenko, Chris Fanini and Dan Veltri now employ more than 300 people globally, with about half of them located inside their San Francisco headquarters.
Weebly serves 32 million users in 170 countries. The startup raised $35 million in its last round of funding, in which is hasn't used, and says its been cash flow positive since 2009.
The company even built a small library inside their office and if you pull out the right book, the book shelf opens to reveal a secret room.
"This was an ode to the speak easy era of the building," Veltri told CNBC. "It used to be a liquor distribution center and got shut down during the prohibition."
