Ming Min Hui, executive director of Boston Ballet, is unique in her field. As a young, Asian American woman with a HBS MBA and a background in finance, she focuses on ensuring the ballet company stays true to its art form and still relevant to its times.

Harvard Business School Assistant Professor Edward Chang and Hui join host Brian Kenny to discuss the case Ming Min Hui at Boston Ballet. They explore how she balances the past, present, and future—and how these lessons translate from this nonprofit arts organization to any company, anywhere.

Bill Wilson was an incredibly entrepreneurial young man with tremendous potential. He was also a drunk, until an epiphany made him sober. With his personal drive and fellowship with former drinking buddies, Wilson built a social movement and worldwide organization.

In this episode of Cold Call, HBS Professor Robert Simons joins host Brian Kenny to discuss the case, “Bill Wilson: Changing the World.” They explore how Wilson navigated life’s choices, transformed his life and those of others, and left a lasting impact on the world.

Keurig Green Mountain (KGM) invented a category and became a household name in at-home coffee brewing in North America. But by the early 2010s, the public company suffered a series of product missteps, negative media scrutiny, and challenging partner relationships. In late 2015, the company was acquired by JAB Holding Company. The new CEO Bob Gamgort first strengthened partnerships, raised productivity, and reduced costs. In 2017, the company then focused on new growth. Gamgort considered four major options: take the company public again through an IPO; set out for greater global expansion; combine with another coffee business to become a larger player in North American coffee; or diversify beyond coffee through a “pure play beverage” strategy. In this conversation, HBS Senior Lecturer David Fubini and Research Associate Patrick Sanguineti discuss the four strategic options from their case study, “Keurig: A Return to Growth.”

The 2023 movie Barbie and its accompanying marketing blitz reinstated a celebrated icon at the forefront of cultural conversation. This sudden goodwill stood in contrast to decades of criticism of the Barbie brand. Although proponents had celebrated Barbie for her promise to “inspire the limitless potential in every girl,” detractors felt that the doll promoted a narrow beauty standard and perpetuated gender stereotypes. In this episode of Cold Call, HBS Professor Elie Ofek and coauthor Ryann Noe join host Brian Kenny to discuss the case “Barbie: Reviving a Cultural Icon at Mattel.” They explore how Mattel planned to sustain the Barbie brand’s positive momentum and replicate its success across other toy brands.

The company also saw the potential of Gen AI to power innovative products beyond languages. CTO Severin Hacker envisioned a future in which AI would transform the app into an educational ecosystem, tapping into the $56 billion edtech market. HBS Senior Lecturer Jeffrey Rayport and coauthor Nicole Keller join host Brian Kenny to discuss the case “Duolingo: On a Streak” and the long-term benefits and risks of this diversification strategy.

In 1952, Palenstinian refugee Elia Nuqul started a trading business in Jordan. Nuqul Group subsequently grew into one of the country’s largest family businesses.

In this episode, FHH chairman Ghassan Nuqul and HBS Senior Lecturer Christina Wing join host Brian Kenny to discuss enduring family businesses, a founder’s  legacy, and how business decisions affect family ties in the case “Ghassan Nuqul and the Nuqul Group: Preserving a Father's Legacy.”

Many observers were excited to have the two-time Super Bowl champion as CU’s new head coach. But some questioned whether Sanders had the experience needed to turn around a team in a highly competitive athletic conference. Others wondered whether his “old school” leadership style would be effective with today’s student-athletes. Still others doubted whether his approach would be sustainable. In this conversation with host Brian Kenny, Harvard Business School Senior Lecturer Hise Gibson discusses Sanders’ leadership style and effectiveness exhibited in the case study “Deion Sanders: The Prime Effect.”

Sebenius joins host Brian Kenny and a live audience of Harvard Business School alumni to discuss how to deal with tough negotiators effectively and ethically.

With operations in 70 countries and 20,000 employees, Pernod Ricard is a leader in premium international spirits. The company had achieved its leadership position in the market largely through strategic acquisition and an ability to build and grow its brand over time. But pressure to continually expand its extensive brand portfolio in order to meet customer demand meant that its traditional analog processes were not allowing the company to effectively manage its huge portfolio of products. In response, the company launched four key digital programs (KDPs) aimed at using data and artificial intelligence to automate processes and enable data-driven decision-making.

Katie Holyfield and Taylor Matkins founded Lucky Ones Coffee in 2017, a coffee shop with a mission to create jobs in Park City, Utah, for people with intellectual and developmental disabilities.

Early in her career Brooke Boyarsky Pratt (MBA 2013) enjoyed considerable success in roles at McKinsey and Berkadia, a Berkshire Hathaway portfolio company. But a routine visit to the doctor in 2020, where she experienced weight stigma yet again, led her to address the problem of obesity care. Boyarsky Pratt had struggled with her weight since she was young. So when she started knownwell, an integrated weight and primary care provider that was designed to support people with obesity, it was a huge step for her both personally and professionally. In the spring of 2023, knownwell opened its first weight-inclusive clinic in the Boston area. But Boyarsky Pratt had to make a fundamental decision on how she wanted to grow the company. Should she grow slowly and build a small footprint of clinics in the Boston area over the next few years? Or should she scale fast to potentially help millions of people across the U.S.?
