David Sacks

Overview

David Sacks entered the White House in December 2024 as America’s first AI and crypto czar — and left the job in March 2026 with the clock running out exactly as planned. Bloomberg His appointment carried a built-in expiry date: as a special government employee, Sacks was legally permitted to work only 130 days a year, and he said the time had simply run out. PYMNTS That pre-engineered ending is the detail most biographies of the venture capitalist skip — but it explains why a man at the center of Washington’s tech-policy apparatus moved, without drama, to co-chairing the President’s Council of Advisors on Science and Technology instead.

Before government, Sacks was a defining figure of two Silicon Valley eras: chief operating officer of PayPal during the dot-com boom, then founder of Yammer, the workplace-chat company Microsoft bought for $1.2 billion in 2012, and later co-founder of the venture firm Craft Ventures in 2017. Bloomberg Along the way he took a detour into Hollywood, producing the 2005 satire Thank You for Smoking, and became a public voice of tech-politics as a co-host of the All-In Podcast. Bloomberg

A government job designed to expire

Trump announced Sacks on Truth Social in early December 2024, saying he would “guide policy for the Administration in Artificial Intelligence and Cryptocurrency, two areas critical to the future of American competitiveness,” and would also lead the Presidential Council of Advisors for Science and Technology. Bloomberg The appointment was a reward for one of Trump’s most prominent Silicon Valley backers: Sacks had co-hosted a fundraiser at his San Francisco home with tickets at $300,000 a head. Bloomberg

The terms of the job were unusual from the start. As a special government employee, Sacks did not have to divest his assets or publicly disclose them, did not face Senate confirmation, and did not have the direct power of a formal office — but he was capped at 130 days of service per year. Bloomberg His firm said at the outset that he would stay on at Craft Ventures, a promise that held throughout his tenure. Bloomberg

The flagship deliverable of his tenure was the Strategic Bitcoin Reserve. In March 2025, Trump signed an executive order creating the reserve, capitalized with bitcoin the federal government already owned through criminal or civil asset forfeiture — with commerce and treasury secretaries authorized to develop “budget-neutral” strategies to acquire more, imposing no incremental costs on taxpayers. Reuters Sacks announced the details himself, declaring that “The U.S. will not sell any bitcoin deposited into the Reserve” and that it would be kept as a “digital Fort Knox.” Reuters He estimated the government held roughly 200,000 bitcoin and claimed premature sales had already cost taxpayers $17 billion — figures Reuters noted came with no clear methodology.

When the 130 days were up, Sacks told Bloomberg Television on March 26, 2026, that the time was simply gone: “We had 130 days. We’ve now used up that time.” PYMNTS The day before, the White House had named him co-chair of PCAST alongside Michael Kratsios, the former chief technology officer and tech investor, on a 13-member council including Mark Zuckerberg, Sergey Brin, Larry Ellison, Marc Andreessen, Jensen Huang and Lisa Su. AFP The council dates to the Franklin Roosevelt era and is purely advisory — it produces reports and recommendations with no regulatory or enforcement powers. AFP Sacks framed the move as an expansion, not a demotion: as PCAST co-chair he could make recommendations “on not just about AI, but an extended range of technology topics.” PYMNTS

From PayPal to Yammer to Craft

Sacks’s path to the West Wing began in the late 1990s at PayPal, where he served as chief operating officer alongside figures like Elon Musk and Peter Thiel — the cohort later known as the “PayPal Mafia.” Bloomberg After PayPal was sold to eBay, he turned briefly to Hollywood and produced the 2005 film Thank You for Smoking, an unlikely résumé line for a future tech envoy. Bloomberg Back in Silicon Valley, he founded Yammer, the enterprise social-network service Microsoft acquired for $1.2 billion in 2012, and in 2017 founded Craft Ventures, which backed companies including Musk’s SpaceX.

Born in South Africa and educated at Stanford, Sacks became one of the most visible political voices in tech through the All-In podcast, which Trump called the “top podcast in Tech” in his announcement post. Bloomberg His closeness to the administration’s orbit included a close association with Vice President-elect JD Vance, the investor-turned-senator. Bloomberg But the Trump-era crypto push was not without scrutiny: the president’s family had launched meme coins and held a stake in the crypto platform World Liberty Financial, raising conflict-of-interest questions that followed the administration’s digital-asset agenda.

What this profile does not claim

It does not claim that the AI and crypto czar position was abolished after Sacks’s departure — that assertion appears only in sources this profile did not read in full. It does not treat his $17 billion and 200,000-bitcoin estimates as independently verified figures; Reuters explicitly noted the methodology was unclear. Reuters It does not catalog his private investments or net worth, which are not documented in the sources used here. And it presents his move to PCAST as he framed it — a continuation on a broader portfolio — while noting that the council is advisory only and has no enforcement authority. AFP
