David Sacks is a technology entrepreneur, venture capitalist, and co-host of the All-In Podcast. As a member of the legendary "PayPal Mafia," Sacks helped build one of the most influential companies in internet history before founding Yammer and establishing Craft Ventures as a leading enterprise software investor.
Early Life and Education
Born in Cape Town, South Africa in 1972, Sacks immigrated to the United States as a child. He attended Stanford University, where he earned a BA in Economics (1994) and later a JD from Stanford Law School (1998).
At Stanford, Sacks became friends with Peter Thiel, editing the conservative student newspaperThe Stanford Review together. This partnership would later prove pivotal in his career trajectory.
Before fully entering tech, Sacks co-authored the controversial book "The Diversity Myth" (1995) with Peter Thiel, critiquing multiculturalism in higher education. The book remains divisive and is rarely discussed by Sacks today.
PayPal: The Foundation
Joining PayPal (1999)
In 1999, Peter Thiel recruited Sacks to join Confinity (which later became PayPal) as Chief Operating Officer. Sacks was responsible for building the product and operations infrastructure that would scale PayPal from a startup to a payments giant.
Key contributions at PayPal:
- Product leadership - Oversaw development of core payment features
- Anti-fraud systems - Built fraud detection that saved millions
- Operations scaling - Managed explosive user growth (10M+ users by 2001)
- IPO preparation - Helped prepare company for public markets
eBay Acquisition (2002)
eBay acquired PayPal for $1.5 billion in 2002. As COO, Sacks received a substantial payout that provided the capital for his next ventures. More importantly, he became part of the "PayPal Mafia" — the group of former PayPal executives who went on to found or fund companies like LinkedIn, YouTube, Tesla, SpaceX, Palantir, and Yelp.
PayPal Mafia Connections:
- Peter Thiel - CEO, later founded Palantir and Founders Fund
- Elon Musk - Co-founder (X.com merger), later Tesla and SpaceX
- Reid Hoffman - EVP, later founded LinkedIn
- Max Levchin - CTO, later founded Affirm
- Keith Rabois - VP, later Khosla Ventures and Founders Fund
Yammer: Enterprise Social Networking
Founding Yammer (2008)
After PayPal, Sacks tried several ventures (including Geni.com, a family networking site) before hitting his stride with Yammer in 2008. Yammer was an enterprise social network designed to improve internal communication at companies.
The pitch: "Facebook for the enterprise" — but secure, compliant, and IT-approved.
Explosive Growth
Yammer's freemium model drove viral adoption:
- Free for individuals to join their company network
- Paid upgrades for enterprise features (admin controls, integrations, analytics)
- Network effects: value increased as more employees joined
- 85% of Fortune 500 companies used Yammer by 2012
Microsoft Acquisition (2012)
Microsoft acquired Yammer for $1.2 billion in 2012, one of the largest acquisitions in enterprise social software history. Sacks stayed on to integrate Yammer into Microsoft's Office 365 suite.
While Yammer eventually lost ground to Microsoft Teams and Slack, the acquisition validated enterprise social networking and made Sacks a proven founder-operator in the SaaS world.
Craft Ventures: Building a VC Powerhouse
Founding Craft Ventures (2017)
In 2017, Sacks founded Craft Ventures, a venture capital firm focused on enterprise software, SaaS, and marketplace businesses. The firm's strategy: back experienced founders building category-defining companies.
Fund size: Started with $350M Fund I, now manages over $2B+ across multiple funds.
