Özyeğin Social Investments was founded by Hüsnü Özyeğin, one of Turkey’s most successful entrepreneurs, with a focus on education, health, gender equality, rural development, and disaster relief in Turkey. The company and the Özyeğin family have spent decades serving and improving communities in need. Their efforts led to the creation of one of Turkey’s top universities, the establishment of schools and rehabilitation centers, post 2023 earthquake humanitarian shelter and facilities, nationwide campaigns and an internationally recognized educational training initiative for young children, among other achievements.

Harvard Business School senior lecturer Christina Wing and Murat Özyeğin (MBA 2003) discuss how the company is a model for making a significant impact across multiple sectors of society through giving and how that legacy can be sustained in the future, in the case, “Özyeğin Social Investments: A Legacy of Giving.”

In the spring of 2021, Raymond Jefferson (MBA 2000) applied for a job in President Joseph Biden’s administration. Ten years earlier, false allegations had been used to force him to resign from his prior U.S. government position as assistant secretary of labor for veterans’ employment and training in the U.S. Department of Labor. Jefferson filed a federal lawsuit against the U.S. government to clear his name and used his entire life savings to pursue the case for eight years. Why, after such a traumatic and humiliating experience, would Jefferson want to work in government again?

Harvard Business School senior lecturer Anthony Mayo traces Jefferson’s personal and professional journey from upstate New York to the U.S. Military Academy at West Point and eventually to President Obama’s administration. Mayo also discusses how Jefferson faced adversity at several junctures in his life, and how resilience and vulnerability shaped his leadership style in the case, “Raymond Jefferson: Trial by Fire.”

Paul English is one of the most imaginative and successful innovators of his generation. He cofounded several companies, including Kayak, before starting Boston Venture Studio, where he is currently a partner. This multimedia case, “Bringing Ideas to Life: The Story of Paul English,” explores his process of creative idea generation, examining how he was able to bring so many ideas to market.

In this episode, Harvard Business School professor Frances Frei and English discuss how to tell the difference between a good idea and a bad one, the importance of iteration, and taking a systematic (but fast) approach to developing new ideas. They also explore how his process dovetails with Frei’s “move fast and fix things” strategy from her recent book.

Harvard University aims to be fossil-fuel neutral by 2026 and totally free of fossil fuels by 2050. As part of this goal, the university is trying to decarbonize its supply chain and considers replacing cement with a low-carbon substitute called Pozzotive®, made with post-consumer recycled glass. A successful pilot project could jump start Harvard’s initiative to reduce embodied carbon emissions, but it first needs credible information about the magnitude and validity of potential carbon reductions.

Harvard Business School professor emeritus Robert Kaplan and assistant professor Shirley Lu discuss the flow of emissions along the supply chain of Harvard University’s construction projects, the different methods of measuring carbon emissions, including the E-liability approach, and the opportunity to leverage blockchain technology to facilitate the flow of comparable and reliable emissions information in the case, “Harvard University and Urban Mining Industries: Decarbonizing the Supply Chain.”

In 2015, Apple debuted the iPhone 6S, which employed a default encryption system preventing both Apple and government authorities from accessing data stored on the device. Then, in 2016, a federal judge ordered Apple to provide technical assistance to unlock the iPhone used by one of the mass shooters in San Bernardino, California. Apple refused to comply.

Years later, as the COVID-19 pandemic swept across the globe in 2020, Apple and Google partnered to develop a contact tracing application that would collect information about users infected with the disease and notify those who they had been in contact with. The app would keep information about infection and contact private, but some governments wanted more access. When Apple and Google declined to provide this information, they sparked a debate about the companies’ responsibilities for their customers’ personal privacy versus public health.

Most recently, in September 2021, Apple decided to delay operating systems updates that included features to fight child sexual abuse. While many praised Apple, others worried that Apple’s new features risked undermining the privacy of all users.

As each of these situations unfolded, Apple CEO Tim Cook had to consider both his responsibilities to global governments and society, as well as to Apple’s customers, employees, and shareholders. Harvard Business School senior lecturer Henry McGee and professor Nien-hê Hsieh discuss the tension between privacy and safety in their cases, “Apple: Privacy vs. Safety” (A), (B), and (C).

Raízen, a bioenergy company headquartered in São Paulo, is Brazil’s leader in sugar and ethanol production and the world’s leading ethanol trader. Since its creation in 2011, the company had primarily produced first-generation ethanol (E1G) from sugarcane, a crop that can also be used to produce sugar.

In 2015, Raízen also started to produce second-generation ethanol (E2G), a biofuel derived from residual and waste materials, such as cane bagasse and straw – which don’t compete with food production. The company’s growth strategy focused on developing and boosting a low carbon portfolio that focused on E2G, based on the belief that Raízen—and Brazil—could help the world decarbonize and profit from the energy transition.

Paula Kovarsky, Raízen’s chief strategy and sustainability officer, was confident the company could become a global green energy champion. But after the board’s approval for the first round of E2G investments, she faced a complex challenge: how to expand the market for second-generation ethanol and other sugar-cane waste biofuels, in order to ensure Raízen’s long-term growth.

Harvard Business School professor Gunnar Trumbull and Kovarsky discuss the company’s strategy for bringing second-generation ethanol to the world in the case, “Raízen: Helping to Decarbonize the World?”

In December of 2020, SolarWinds learned that they had fallen victim to hackers. Unknown actors had inserted malware called SUNBURST into a software update, potentially granting hackers access to thousands of its customers’ data, including government agencies across the globe and the US military. General Counsel Jason Bliss needed to orchestrate the company’s response without knowing how many of its 300,000 customers had been affected, or how severely. What’s more, the existing CEO was scheduled to step down and incoming CEO Sudhakar Ramakrishna had yet to come on board. Bliss needed to immediately communicate the company’s action plan with customers and the media. In this episode of Cold Call, Harvard Business School Professor Frank Nagle discusses SolarWinds’ response to this supply chain attack in the case, “SolarWinds Confronts SUNBURST.”

Should businesses take a stand for or against particular societal issues? And how should leaders determine when and how to engage on these sensitive matters?

Harvard Business School senior lecturer Hubert Joly, who led the electronics retailer Best Buy for almost a decade, discusses examples of corporate leaders who had to determine whether and how to engage with humanitarian crises, geopolitical conflict, racial justice, climate change, and more in the case, “Deciding When to Engage on Societal Issues.”

When Ferrari, the Italian luxury sports car manufacturer, committed to achieving carbon neutrality and to electrifying a large part of its car fleet, investors and employees applauded the new strategy. But among the company’s suppliers, the reaction was mixed. Many were nervous about how this shift would affect their bottom lines.

Harvard Business School professor Raffaella Sadun and Ferrari CEO Benedetto Vigna discuss how Ferrari collaborated with suppliers to work toward achieving the company’s goal. They also explore how sustainability can be a catalyst for innovation in the case, “Ferrari: Shifting to Carbon Neutrality.”

This episode was recorded live December 4, 2023 in front of a remote studio audience in the Harvard Business School Live Online Classroom.

Which sales candidate is a startup’s ideal first hire? What marketing channels are best to invest in? How aggressively should an executive team align sales with customer success?

Harvard Business School senior lecturer Mark Roberge discusses how early-stage founders, sales leaders, and marketing executives can address these challenges as they grow their ventures in the case, “Entrepreneurial Sales and Marketing Vignettes.”
