David O. Sacks’s Experience

Founder/CEO

Yammer.com is a communications tool for enterprises. It makes companies and organizations more productive through the exchange of short frequent answers to the question "What are you working on?" Yammer was originally developed at Geni, and spun out into a new company. It launched on stage at Techcrunch 50 on September 8, 2008, and won Best In Show.

Geni.com is creating a family tree of the whole world, enabling millions of family members to connect, share, and preserve their lives. Geni has won numerous accolades; most recently it was named one of the Top 50 websites by Time Magazine.
Producer

Thank You For Smoking

(Media Production industry)

2002 — 2006 (4 years)

Through my company Room 9, I produced and financed the indie movie THANK YOU FOR SMOKING, for which I was nominated for a Golden Globe. A TV series based on the movie is now in development at USA Network.
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.
