The Night Owl When the clock
strikes midnight, David Sacks is
often still at the office.
David Sacks, a former PayPal executive, has pursued several pet projects
since leaving the online payment company in 2002. He produced the
film Thank You for Smoking and launched Geni, a genealogy website.
For that start-up, he created an internal communication system to help
employees share information. He liked the tool so much, he spun it off
into a new company called Yammer. These days, Yammer, which is based
in San Francisco, employs more than 200 people. Its software is used
by more than 100,000 organizations, including eBay, Thomson Reuters,
7-Eleven, and, of course, Yammer.
