David O. Sacks’s Experience

Founder/CEO

Yammer, Inc.

(Privately Held; Computer Software industry)

September 2008 — Present (1 year 3 months)

Yammer.com is a communication and collaboration tool for companies and organizations. Initially dubbed "Twitter for enterprises" because of its focus on microblogging, Yammer has extended its functionality to become a full-fledged social network for inside your company. Yammer was originally developed as an internal productivity tool at Geni, and spun out into a new company after winning TechCrunch50 in September 2008. Today, employees at over 40,000 businesses worldwide use Yammer, including many Fortune 1000 companies.
Founder/CEO

Geni, Inc.

(Internet industry)

June 2006 — Present (3 years 6 months)

Geni.com is creating a family tree of the whole world, enabling millions of family members to connect, collaborate, and preserve their lives. With over 25 million people connected in one family tree, Geni is rapidly becoming the Wikipedia of genealogy. Geni has won numerous accolades; Time Magazine named it one of the Top 50 websites in 2008.
Producer

Thank You For Smoking

(Media Production industry)

2003 — 2006 (3 years )

Through my company Room 9, I produced and financed the independent film THANK YOU FOR SMOKING, for which I was nominated for a Golden Globe. The movie was acquired and distributed by Fox Searchlight.
COO

PayPal

(Public Company; 5001-10,000 employees; ebay; Internet industry)

1999 — 2002 (3 years )

As Chief Operating Officer, I was PayPal's product leader, managed 700 employees, and built many of our key teams.

I was responsible for product management and design, sales and marketing, business development, international, customer service, fraud operations, and human resources functions at PayPal.

During my tenure, we grew payment volume from $0 to $500 million/month and revenue from $0 to $240 million/year. We beat eBay on its own platform, winning the auction payments space. We became the world's #1 financial website, from nothing. We introduced business accounts and made our users pay. We expanded into multiple currencies and over 80 countries. Finally, we successfully IPO'd and became a public company, before ultimately selling to eBay for $1.5 billion.
