HBR IdeaCast is Harvard Business Review's weekly interview show, co-hosted by Adi Ignatius and Alison Beard, who lead conversations with one guest per episode. Most episodes are tied directly to a recently published HBR article or book, with the guest walking through their research, data, and recommendations for managers. Guests are predominantly academics and authors: Marcus Buckingham on customer and employee loyalty, Gautam Chalagala of IMD Business School on sustainability strategy, Andy McAfee of MIT on AI adoption, Don Tapscott on AI agents and 'Identic AI,' Stefan Volk of the University of Sydney on circadian rhythms at work, and Tim Elmore on managing Gen Z employees. A recurring throughline across recent episodes is artificial intelligence's effect on management and productivity, covering AI-generated 'workslop,' agentic AI, and how leaders should structure AI adoption rather than mandate it top-down. Other frequent subjects include workplace scheduling and biology (chronotypes, circadian troughs), customer experience design, sustainability strategy tied to business value rather than altruism, and generational differences in workforce motivation. Episodes often cite specific studies or statistics, such as a cited $9 million annual productivity loss from AI workslop or a 0.12 correlation between sustainability and profit, rather than relying only on anecdote. The format is consistent: a short framing segment from the hosts followed by a guest interview, occasionally referencing HBR's Leadership Summit or other HBR programming. The show is aimed at managers, executives, and organizational leaders looking for research-backed perspectives on strategy, leadership, and changing workplace norms. Production is credited to HBR staff including producers Rob Eckhart, Mary Du, and Ian Fox, with no narrative or documentary framing — it functions as a recurring interview digest of HBR's own published thinking.
