It's a tough time to lead one of the biggest companies in the world - one that depends on supply chains, physical infrastructure, and top tech talent to stay competitive. But Andy Jassy, who took over as CEO of Amazon from legendary founder Jeff Bezos in 2021, manages in a way that he says helps him stay focused on what is best for their products and ultimately their customers. He explains his decision to get workers back to the office five days a week, why he is building an organization less dependent on managers, and how their artificial intelligence strategy differs from the rest.

Many industries depend on the government to finance infrastructure and research before a true private market can develop. In the case of space, there is still a strong need for public-private collaboration. But as costs drop to reach space, more private-sector companies can enter the market. Matthew Weinzierl is a senior associate dean and professor at Harvard Business School, and Brendan Rosseau is a strategy manager at Blue Origin. They explain the evolving role of the U.S. government to foster innovation and competition as the space economy increasingly privatizes. They also identify the emerging opportunities for businesses and individuals. Weinzierl and Rosseau are authors of the book Space to Grow: Unlocking the Final Economic Frontier.

It's a common story: an immigrant arrives in a new country, sees a need, and works hard to build a successful business around it. Think of Chobani, Google, or Tesla. Indeed, 45 percent of Fortune 500 companies had immigrant founders. While most research focuses on why these people launched their businesses, perhaps more interesting is how they achieved lasting success. Neri Karra Sillaman is an entrepreneurship expert at Oxford University and the founder of luxury leather goods company Neri Karra. She's studied these entrepreneurs and shares her findings, which offer lessons for anyone in the corporate world. Sillaman wrote the book Pioneers: Eight Principles of Business Longevity from Immigrant Entrepreneurs.
