Joe Lonsdale: American Optimist

When Kevin Mandia’s phone rings, it’s often a Fortune 500 CEO or government leader with a billion-dollar problem. How did he become the go-to expert in cybersecurity? What new threats from AI led him back into the arena? And what is he building to protect the good guys?
Kevin began his career in the U.S. Air Force, defending the U.S. military from some of the earliest cyber attacks. He went on to found and lead Mandiant, scaling it into an industry leader which Google acquired in 2022 for over $5 billion. In 2013, he famously exposed China’s massive state-sponsored cyber espionage inside America. Kevin has also served on the National Security Telecommunications Advisory Committee (NSTAC) and the CISA Cybersecurity Advisory Committee. He recently launched Armadin to address new AI possibilities in the cyber domain.
To begin, Kevin takes us behind the scenes of the early cyber skirmishes in the 1990s, and what it was like confronting some of the first cyber incursions from Russia and China, as well as the rise of criminal cyber enterprises. In the early 2000s, Kevin noticed glaring gaps in conventional antivirus approaches and launched Mandiant. Learn how he quickly became the first person that CEOs and governments would call if they’d been hacked. After scaling Mandiant and exiting to Google, Kevin is now back in the arena building cutting-edge solutions to new AI cyber threats. He explains the dramatic increase in the productivity and sophistication of AI agents, and why it’s upending how we build cyber defenses. Find out what he’s most worried about in 2026, and what steps governments and CEOs need to take to secure their networks and infrastructure.

America’s capital markets are the envy of the world, but in recent years, misguided policies have driven innovation offshore and stifled the number of companies going public. SEC Chairman Paul Atkins is reversing course. What’s his plan to make IPOs great again? What will it take for America to become the crypto capital of the world? And does he think we should expand access to private markets for retail investors?
This week, we’re honored to feature a conversation with Paul Atkins, Chairman of the Securities and Exchange Commission. He also served as a commissioner at the SEC from 2002 to 2008, and worked on the staff of two SEC chairmen from 1990 to 1994. Prior to returning to the SEC in 2025, Chairman Atkins was the founder and chief executive of Patomak Global Partners, a financial services firm he founded in 2009.
We begin with Chairman Atkins’ visit to Texas, the significance of Texas’ new business courts, and the importance of innovation in our financial markets. Whereas his predecessor, Gary Gensler, took an adversarial, regulation-by-enforcement approach, he’s embracing new technologies and regulatory clarity. In this vein, the Chairman lays out his strategy for making IPOs great again. Learn why the number of public companies has dropped by nearly half since 2007, and how Chairman Atkins is reforming the rules around litigation and corporate governance to deter activists from harassing America’s builders. We also discuss President Trump’s vision for making America the crypto capital of the world, and what it looks like to provide clear guidelines that promote innovation and protect investors. Finally, we explore the steps he’s taking to enable retail investors to access private markets and other alternative assets.

First, he digitized the entire federal retirement process, cutting it from six months to a few days. Now, he’s overhauling the U.S. government’s online presence, one website at a time. And Joe Gebbia has been in Washington, D.C. less than a year! Learn why he stepped up to serve, and the impact our best minds can have on D.C., in a conversation with our nation’s first Chief Design Officer.
As co-founder of Airbnb, Joe turned a living-room experiment into a multi-billion dollar global brand. Then, he launched Samara, helping homeowners reimagine their yards with state-of-the-art Accessory Dwelling Units. He also sits on the boards of Airbnb, Airbnb.org, and Tesla. Last February, he joined Elon Musk and the DOGE team in D.C. to overhaul retirement for federal workers, before setting his sights on modernizing the nation’s 27,000 .gov websites.
We begin with Joe’s journey to D.C., and how a former Democrat came to support President Trump and take on problems that have plagued government for decades. His first challenge: federal retirement and “the mine” — a storage facility inside a Pennsylvania mountain that houses all federal employees’ retirement paperwork. Learn how Joe worked alongside career civil servants to transform a broken, six-month slog into a digital-only process that takes mere days. Now, he’s set his sights even higher: overhauling the government’s digital portals and delivering an Airbnb-like experience, starting with the Trump Gold Card, TrumpRX.gov, and, more recently, RealFood.gov and TrumpAccounts.gov. We go inside the Oval Office and Joe reveals his conversations with Pres. Trump on the importance of aesthetics, functionality, and design. Drawing inspiration from President Nixon’s beautification initiative, he worked with Pres. Trump to launch the government’s first digital makeover. It’s inspiring to see Joe’s leadership, and if you, or someone you know, wants to join his elite team of designers and engineers, there are a few spots remaining.

Emil Michael directs the U.S. military’s research and development of advanced technologies. Previously, he led global business growth for Uber — one of the fastest moving organizations in Silicon Valley history. Can he bring that startup speed to the Department of War? What are the six critical areas of innovation he’s prioritizing? And how is he investing in these key technologies to bolster the defense industrial base?
We’re honored to go inside the Pentagon for a special episode with Emil Michael, Chief Technology Officer and Under Secretary of War for Research & Engineering. He oversees the Defense Advanced Research Projects Agency (DARPA), the Office of Strategic Capital, and other critical organizations. Prior, he helped scale multiple businesses, including D-Wave Systems, Tellme Networks, and Uber Technologies. Earlier in his career, he also served as a White House Fellow and later on the Defense Business Board.
We begin with Emil’s decision to join the Trump administration, and why he believes this is a generational opportunity to transform the culture and pace of innovation inside the Pentagon. Learn how he rolled out GenAI.mil (Google’s Gemini) to the entire force — roughly three million people — in a matter of months. Next, we dive into his decision to pare down the all-important Critical Technologies List, which drives the Pentagon’s R&D spending, from 14 areas to six. Then, we discuss the Department’s shift to a “commercial first” approach and what that means for the defense industrial base. Finally, we cover his priorities for the Office of Strategic Capital, plus how he’s thinking about talent and encouraging our best and brightest to step up and serve the country.

Chris Sununu is an MIT-educated engineer who won four terms as governor of New Hampshire. Now, he's leading the charge for a balanced budget amendment to the U.S. Constitution. What are his key lessons in political leadership? Why is he telling Harvard students to be wary of AI? And are real fiscal constraints on Washington, D.C. close to becoming reality? The former governor of New Hampshire, Chris Sununu is now the President and CEO of Airlines for America and National Chair and Board Member of Balanced Budget Now, which has secured 27 of 34 states required to call a convention for a constitutional amendment. They're on the cusp of landing several more states and closing in on a convention of states, which he hopes will pressure Congress to step in and pass an amendment through the traditional process. This is a generational opportunity to upend how D.C. operates; my friends and I are supporting their work and hope you will too. We begin with Gov. Sununu's path to politics, and how he succeeded in lowering taxes, expanding school choice, and combating an opioid epidemic with a sharply divided state legislature. Next, we talk about the right political strategies for cutting wasteful spending, lessons from DOGE, and what he would do differently to make DOGE an enduring movement. Then, we dive into his efforts to get a balanced budget amendment across the finish line. Learn why nearly all states (even California, albeit it plays games with pension math) have a balanced budget requirement and what it will take to get D.C. on board. Finally, we discuss the AI revolution and why he's bullish on plumbers and welders over students pursuing "elite" white-collar professions. As Gov. Sununu suggests, more tradespeople and fewer lawyers might not be a bad thing for our society.
