HBR IdeaCast

What does it look like for a business in 2025 to build a strategy around sustainability? In this Future of Business series, IdeaCast hosts Alison Beard and Adi Ignatius sat down with four leading CEOs to understand where global business is going. In this episode, host Adi Ignatius speaks with Poul Weihrauch, CEO of Mars, about how he manages the family-owned global pet care, snacking and food company. They discuss balancing short-term performance with long-term goals, resilience, and the business case for sustainability-driven innovation.

Most companies say they want to be more innovative, agile, and customer-centric. But in reality, many still operate like 20th-century factories: hierarchical, risk-averse, and slow. Jana Werner, executive in residence of enterprise strategy at Amazon Web Services, argues that organizations should instead think of an octopus: an organism that manages complexity, can work in many different modes with some autonomy, but all moving in concert toward a common goal. Werner says the future belongs to companies that distribute decision-making, empower teams at the edge, and treat innovation as everyone’s job, and explains steps you can take as a leader to make this cultural shift. She's the coauthor along with Phil Le-Brun of the HBR article "Become an Octopus Organization" and the book, The Octopus Organization: A Guide to Thriving in a World of Continuous Transformation.

What are CEOs across industries doing to build resilience and strong cultures in an age of uncertainty? In this Future of Business series, IdeaCast hosts Alison Beard and Adi Ignatius sat down with four leading CEOs to understand where global business is going. In this episode, host Alison Beard speaks with Noubar Afeyan, the CEO of Flagship Pioneering and Chairman of Moderna. Afeyan shares the organizational models and practices that work best to produce innovation, the difference between managing risk and managing uncertainty, and what separates true breakthrough innovation from everyday, incremental improvements.

It's harder than ever for companies to get their marketing messages in front of the right customers. One increasingly popular -- but also risky -- tactic is fastvertising, the rapid development of ads that tap into a cultural moment, aiming to increase brand relevance and awareness. Harvard Business School associate professor Ayelet Israeli shares pitch-perfect examples, including those from her coauthor, the actor Ryan Reynolds, and his marketing firm Maximum Effort. She explains the importance of timing, describes the talent, culture, and processes you need to succeed, and outlines how to extend the impact of these ads. Ayelet, along with Leonard Schlesinger, Matt Higgins, and Ryan Reynolds, wrote the HBR article "Marketing at the Speed of Culture."

Even in difficult times, leadership must be about empathy, authenticity, fairness and service. That's according to Darren Walker, the outgoing CEO of the Ford Foundation, a nonprofit with an endowment of billions of dollars and a charge to reduce poverty and injustice. Drawing on his own upbringing in rural Texas to his time at the helm of one of the world’s largest philanthropies, Walker explains how inequality erodes hope, why discomfort is essential for meaningful change, and how leaders can build the courage to speak honestly.

In uncertain times, leaders at all levels can learn from what the world's best CEOs are doing to protect themselves and forge a path ahead. In this Future of Business series, IdeaCast hosts Alison Beard and Adi Ignatius sat down with four leading CEOs who manage across different industries and geographies to understand where global business is going. In this episode, host Adi Ignatius speaks with Walmart CEO Doug McMillon, who since announced he'll be retiring in early 2026. They discuss how the world's largest company makes it through global disruption and supply chain shocks, their ongoing digital transformation including the implementation of AI, and how McMillon aims to stay close to the original purpose of the company.

Geopolitics are no longer a tailwind for businesses today, opening markets and boosting global trade. Instead, argues ESSEC Business School associate professor Srividya Jandhyala, rising national security concerns and protectionist economic policies have created a headwind for many organizations, and that's changing how executives need to operate. She explains what’s changed in the global balance of power, how it's affecting even small to medium-sized companies and unexpected industries —from shrimp farming to fast fashion -- and why leaders need new talent and risk management strategies to adapt. Jandhyala is the author of the book The Great Disruption.

In uncertain times, leaders at all levels can learn from what the world's leading CEOs are doing to protect their companies from risk and forge a path forward. In this Future of Business series, IdeaCast hosts Alison Beard and Adi Ignatius interview four chief executives from different industries and geographies to better understand where global business is going. In this episode, Alison speaks with Sim Tshabalala, the CEO of Standard Bank. He explains how his childhood in apartheid South Africa informed his decision to go into finance, why purpose drives the company's approach to everything from strategy to customer service, and the role he believes businesses like his must play in promoting sustainable growth.

Leadership takes daring and steadfastness even in the best of times. In eras of shaky political, economic, and social stability, researcher and author Brené Brown argues it is more important than ever to stay true to your values, make thoughtful decisions, and avoid succumbing to external pressures. The podcast host and University of Houston research professor shares what she's learned in her latest studies and explains how to avoid reactivity as an organizational leader navigating a distrusting and disconnected world. Brown is author of Strong Ground: The Lessons of Daring Leadership, the Tenacity of Paradox, and the Wisdom of the Human Spirit.

It isn't always easy to feel like you can have it all: career, family, hobbies and inner peace. Harvard professor Arthur C. Brooks studies happiness and says it is a direction, not a destination. Brooks believes happiness is especially important for leaders, as the higher you climb the more stressful the job can get - and the wider impact you can have on others. Live in conversation at Harvard Business School's Klarman Hall, he speaks with IdeaCast host and HBR editor at large Adi Ignatius about the importance of empathy and having a greater purpose in your life, not just in your career. Brooks is author of the book The Happiness Files: Insights on Work and Life.

When Wikipedia was founded in 2001, the idea that people around the world could come together to create an accurate online encyclopedia covering virtually any topic seemed far-fetched. But today many people see the website as a trusted source of well-curated and -cited information. That's because of careful decisions that its leaders made about how to operate. Cofounder Jimmy Wales explains how introducing a simple purpose, insisting on certain rules of engagement, and other strategies helped the organization to build trust with contributors and users -- and maintain it even in a world bombarded by misinformation. Wales is the author of The Seven Rules of Trust: A Blueprint for Building Things That Last.

When you hit a roadblock in your career, it's easy to blame external factors like the economy, the organization, or your boss. But leaders are just as often stymied by their own beliefs about how they need to show up and operate at work, shares executive coach Muriel Wilkins. Through decades of work counseling high-powered executives, she's uncovered the seven main ways that people limit their own success and has advice on how to overcome those mental blocks. Wilkins is author of the HBR article "The Hidden Beliefs That Hold Leaders Back" and the book Leadership Unblocked: Break Through the Beliefs That Limit Your Potential.

When it first came out in 2005, Freakonomics unearthed the hidden side to everything, helping bring behavioral economics to the forefront of popular culture. But it also has had lasting impacts on how leaders understand problems, how advertisers understand consumers, and how we all understand the workplace. Coauthor Stephen Dubner explains the difficulty of bringing complex economic concepts to the masses, what's surprised him about the hidden side of everything, and what he sees as the impact of his work. Dubner is coauthor of Freakonomics: A Rogue Economist Explains the Hidden Side of Everything and host of the Freakonomics podcast.

In a crowded media and marketing environment, it can be hard to catch the attention and imagination of consumers. Two people paying close attention to what's working now are Tonight Show host Jimmy Fallon and seasoned marketing executive Bozoma Saint John, and they've just launched a reality show called "On Brand" to showcase the work that creatives and companies do to sell their ideas, products, and services. Fallon and Saint John share what their different career paths have taught them about personal branding, working collaboratively, managing teams, and how to navigate the changing media landscape.

Cory Doctorow, author and digital rights advocate, argues that big tech companies from Facebook to Google and beyond have evolved - or devolved - in a disappointing way. He says that many large tech companies begin with a good product, but that over time they prioritize first business customers, and then ultimately shareholders and profits over end users. That creates a decline in service quality, and Doctorow explains why that's bad for customers, companies, and the broader economy and society. Doctorow wrote the new book Enshittification: Why Everything Suddenly Got Worse and What to Do About It.

Courage involves taking bold action despite uncertainty and fear. In a volatile business environment, it's hard to be brave. But Ranjay Gulati, a professor at Harvard Business School, says that there are strategies any of us can use to get improve our ability to make smart bets on the future. He's studied dozens of leaders across industries and explains how they embolden themselves and their organizations by building a positive narrative around the mission, cultivating self-confidence, stepping their way into a better understanding of the situation, finding connection, and staying calm. Gulati wrote the HBR article "Now is the Time for Courage" and the book How To Be Bold: The Surprising Science of Everyday Courage.

As a leader, psychology is fundamental to your success - whether that means understanding consumer behavior, team dynamics, or even your own biases and blind spots. Harvard professor Steven Pinker says that an important phenomena to understand is that of common knowledge and its downstream effects. It's the idea that there is power in knowledge, but also power in knowing what other people know - and that when a large group of people know what others around them know, and vice versa, that's when major change can happen. He explains how common knowledge underlies meme stocks, the rise of crypto, meeting etiquette and the success of Super Bowl ads. Pinker wrote the new book When Everyone Knows That Everyone Knows . . .: Common Knowledge and the Mysteries of Money, Power, and Everyday Life.

Across industries, organizations are struggling to move as quickly as they need to on key priorities and new initiatives. The solution for many, says Stanford's Melissa Valentine, might be "flash teams" -- project groups that can be instantly, efficiently, and cost-effectively brought together and organized via online labor markets and AI and other digital tools to solve any problem. She explains why companies and leaders should embrace this new type of collaboration, how flash teams work in practice, and the pitfalls to look out for. Valentine is coauthor along with Michael Bernstein of the book Flash Teams: Leading the Future of AI-Enhanced, On-Demand Work.

A fast-moving lie can do more damage to a company’s reputation than a slow, careful truth can fix. Executives who think fake news is just a political problem are underestimating its reach and cost. Patrick Haack, professor of strategy and responsible management at HEC Lausanne, explains why traditional responses like silence or fact-checking aren’t enough. He outlines what companies should be doing instead: building credibility in advance, monitoring for signs of virality, and enlisting outside allies to push back. It’s a playbook designed not just to correct the record but to protect trust before it erodes. Haack is coauthor of the HBR article “How to Counter Fake News.”

At every stage of leadership, it's important to hand some tasks and even decisions off to team members to foster their development and free up your time for higher level work. But even seasoned bosses often have trouble effectively delegating. Elsbeth Johnson, senior lecturer at the MIT Sloan School of Management, explains the four main reasons why we struggle -- both internal and external -- and outlines strategies for overcoming them to level up your delegation game. Johnson wrote the HBR article "Why Aren’t I Better at Delegating?"

Leading an organization is a serious job, but Adam Christing argues that humor is a shortcut to building trust at an organization - and without it, you might be missing out on an important leadership tool. Christing is a comedian, speaker and author and he walks through five main kinds of humor that are most effective at work. It's not about knock-knock jokes, he says, but finding a style that's authentic to you. Christing is author of the book The Laughter Factor: The 5 Humor Tactics to Link, Lift, and Lead.

Amid great economic, political, and technological change, it can feel impossible to predict what might happen next. Nick Foster, a futurist and designer who has worked at Google X, Sony, and elsewhere, says that most of us struggle because we tend to fall into one pattern of thinking about the future. A better approach -- for leaders, teams, and entire organizations -- is to consider the long-term view through multiple lenses, understanding the strengths and weaknesses of each. He explains how more deep and rigorous thinking and discussion on these issues can yield better outcomes for businesses of all kinds. Foster is the author of the book Could, Should, Might, Don't: How We Think About the Future.

AI ecosystems are moving fast, and smart leaders are considering all options when it comes to staying competitive. Amit Joshi is a professor at IMD Business School, and he argues that leaders should be looking to Chinese technology as a possible way to power up their strategies and growth. The adoption comes with some risks that leaders must be aware of, Joshi explains, but a careful combination of multiple AI tools could be the answer. He also explains just how far Chinese AI platforms have come since the arrival of DeepSeek, what makes them different, and examples of how companies are integrating them into their tech stacks the right way. Joshi is coauthor of the HBR article "How Savvy Companies are Using Chinese AI."

Whether your organization encourages working from home or the office, much of your business is no doubt conducted virtually — over email, on Slack, or via Zoom meetings. But few of us think very carefully about how to most effectively use these tools or which to employ when. And few teams and companies have established best practices for virtual communication, which can hurt collaboration, sales, engagement, and performance. Andrew Brodsky, a professor at the McCombs School of Business at the University of Texas at Austin who has researched these issues, outlines practical ways to be more conscientious and intentional about our communication choices and patterns. Brodsky wrote the book Ping: The Secrets of Successful Virtual Communication.

It might seem risky to base decisions as a leader on your gut feeling or intuition. But Laura Huang's research has found that intuition isn't just an arbitrary thought or emotion; that it’s the culmination of years of data and observation, and that it is worth listening to. The Northeastern University professor shares what she's learned about intuition, how we can recognize it and tap into it, and why it is a strength for business leaders. She's the author of the book You Already Know: The Science of Mastering Your Intuition. She also wrote the HBR article "How CEOs Hone and Harness Their Intuition."
