He was PayPal's chief operating officer and product leader, taking the company from startup to IPO and eventual sale to eBay for $1.5 billion. Subsequently, he founded Geni.com, a genealogy website that enables millions of family members to collaboratively build an online family tree. Geni was acquired by MyHeritage in 2012. He also produced and financed the movie "Thank You For Smoking." Also in 2012, David sold Yammer to Microsoft for $1.2 billion.
