Cold Call

In 2021, a breakthrough in sanitation technology – developed under the Gates Foundation’s “Reinvent the Toilet” challenge – stood ready for commercialization. The Single User Reinvented Toilet (SURT) offered an off-grid, self-contained system capable of processing waste, generating water, and reducing environmental impact. Turning this technical success into a viable product, however, meant confronting intertwined challenges around behavior change, infrastructure compatibility, financing models, and stakeholder incentives. Harvard Business School Assistant Professor Maria Roche and SURT engineer Dr. Shannon Yee join Brian Kenny to discuss the case “Toilets for the Underserved: The SURT Commercialization Challenge” and the central question of how to launch and then scale a technology particularly important for underserved markets, but not a lucrative short term investment opportunity.

After launching Wasabi Technologies, a successful cloud storage company, founder and CEO David Friend was ready to scale the venture rapidly. The company had focused primarily on direct sales, but an opportunity to pivot toward channel sales was on the horizon. However, making this pivot would mean changing its sales, marketing, and staffing strategies dramatically, and effectively veering the company away from its already successful course. Harvard Business School Senior Lecturer Lou Shipley joins Brian Kenny to discuss the case, “Wasabi Technologies” and the questions Friend wrestled with: Was channel sales the right play for the burgeoning cloud storage provider? If so, how should it best be implemented? They also explore ideas connected to Shipley’s new book, Unlikely Entrepreneurs.

Software startup InsightSquared had recently hit $2 million in revenue and secured an $8 million round of venture capital. However, the founders disagreed on the path ahead, specifically on the sales and marketing plan. Should they focus on a sales-centric approach to growth or a marketing-centric one?

Harvard Business School Senior Lecturer Mark Roberge joins Brian Kenny to discuss the case, “InsightSquared: Developing the Sales and Marketing Plan” and ideas related to his new book, The Science of Scaling.

They explore the benefits and potential drawbacks to the bank “oversharing” information with customers.

The U.S. Men’s Olympic speed skating team devised a new approach to the team pursuit event following their disappointing performance in the 2018 Winter Olympics. The team saw promising initial results from their innovations, but they faced a decision about whether to reveal their new techniques. The U.S. Team’s strategy was easily imitated if competitors witnessed it in a race, but it was a risk not to test it in competition before the Olympics. And, were here possible upsides to imitation if it improved the entire sport? Should they share their techniques, and if so, when? Harvard Business School Assistant Professor Rebecca Karp joins Brian Kenny to discuss the case, “A Winning Strategy: Innovation in Olympic Speed Skating.”

They join Harvard Business School Professor Shane Greenstein and host Brian Kenny to discuss the case “The Acquired Podcast: Scaling the Mic.”

In 2025, Golden Goose, the Italian brand known for its handcrafted, distressed sneakers, was at a crossroads. CEO Silvio Campara had grown the label from a cult favorite into a $650 million global force, but sustaining that growth raised tough questions: Should the company double down on sneakers, expand into ready-to-wear and accessories, or push into emerging international markets? Harvard Business School Professor Juan Alcacer and entrepreneur Alexandre Daillance co-wrote the case “Golden Goose: Reshaping Luxury.” They join host Brian Kenny to explore how the brand has upended traditional fashion norms by embracing imperfection, inviting co-creation, and redefining what it means to scale in the luxury world.

In 2019, Equitable’s CEO, Mark Pearson, set out to change how the 163-year-old financial services firm gets work done. He wanted the firm to speed up decision-making and empower employees through a flatter hierarchy, agile teams, and more opportunities to lead. Most divisions thrived under the new model. Others clung to old habits. Several years in, the effort sheds light on core questions: What does true cultural change look like? What makes it last? And how do leaders bring skeptics along? Harvard Business School Professor Das Narayandas joins Pearson and COO Jeff Hurd to discuss the case “New WOW at Equitable: A New Way of Working.”

In 2020, cryptocurrency exchange Coinbase made two bold organizational moves: going fully remote and banning political discussion at work.

In this episode, Chief People Officer L.J. Brock joins case author and HBS professor Charles Wang and host Brian Kenny to discuss how Coinbase’s strategy, explored in the case “Mission First at Coinbase,” raises critical questions about focus, inclusion, and attracting top talent in a volatile industry.

Apollo Global Management has transformed itself from a traditional private equity giant into an insurance-fueled credit powerhouse—thanks to its acquisition of life annuity issuer Athene. CEO Marc Rowan makes a bold bet that an asset-heavy model, which is backed by hundreds of billions in long-term insurance liabilities, can drive repeatable, superior returns and propel Apollo’s assets under management to $1.5 trillion. However, public markets award Apollo a multitude on its earnings that is far lower than asset-light peers like Blackstone, which highlights important trade-offs. Harvard Business School professor George Serafeim joins host Brian Kenny to discuss the questions raised by the case, Apollo Global Management, and explore what Apollo’s transformation reveals about business-model innovation and risk management in today’s rapidly evolving private markets ecosystem, and what it means to be a modern investment firm.

Tata Power stood at the forefront of India’s energy transition. The firm’s long history was deeply intertwined with the country's development. As Mumbai’s power needs increased, Tata Power built out thermal assets across India, and while thermal power generation remained Tata Power’s mainstay, the firm slowly started diversifying. In 2020, Tata Power boldly announced a commitment to net-zero emissions by 2050, concurrent with a complete phase-down of thermal capacity. It later brought this commitment forward to 2045. To prepare for declining revenues from thermal power generation, Tata Power was actively expanding its renewable business, but stakeholders had concerns about the company’s ambitions. Was the firm’s decision to sacrifice potentially high returns in thermal power generation financially imprudent, or did it position the firm well as India inevitably accelerated its energy transition? In this episode, host Brian Kenny welcomes Harvard Business School Professor Vikram Gandhi and Tata Power CEO Praveer Sinha to discuss the case Tata Power and India’s Energy Transition, and how India’s largest private power producer is reimagining its future.

In April 2024, writer, podcaster, and entrepreneur Tim Ferriss—known for his hugely popular podcast “The Tim Ferriss Show” and NYT-bestselling books like The 4-Hour Workweek—found himself at a crossroads. Although his podcast was generating millions annually, he questioned the sustainability of podcasting and his own competitive advantage given the increasingly saturated market and the advent of AI tools and video-centric formats. He faced a difficult choice: innovate from within his proven format, pivot to entirely new ventures—possibly in film, premium consumer products, or venture capital—or risk a slow decline by maintaining the status quo. Complicating matters further was Ferriss’s desire to start a family, a goal he prioritized above all business ventures. Every month of indecision narrowed his window for successfully transitioning. Senior Lecturer Reza Satchu and Tim Ferriss joined Cold Call host Brian Kenny to discuss the case, “Tim Ferriss: What Might This Look Like If It Were Easy?”

For 35 years, Dollar Tree, a discount retail chain selling general merchandise, had held its fixed price point steady, charging $1.00 for its ever-changing assortment of household items, food, stationery, books, seasonal items, gifts, toys, and clothing. That changed in late 2021, when the company announced that Dollar Tree was raising prices on all goods to $1.25. Harvard Business School Senior Lecturer Jill Avery joins host Brian Kenny to discuss whether the retail chain could remain relevant to its price sensitive shoppers through smart marketing, pricing, and branding strategies in the case, “Dollar Tree: Breaking the Buck.”
