Summary
Caroline Schmidt, 55, chief strategy officer of Edelweiss Corporation, has just led her company through a remarkable turnaround. When Henri Vonlanthen, CEO of Léman Corporation – a company twice Edelweiss’s size – invites her to join Léman’s board, Caroline sees a genuine opportunity: a bigger stage on which to apply the strategic and financial expertise that turned Edelweiss around, and a chance to help a storied family enterprise chart its next chapter. Léman, built over three generations by the Keller family and taken public in 2010, is a company with real assets and real needs: a strong balance sheet but a flat top line, two fast-growing subsidiaries alongside stagnant ones, and no clear long-term strategy. Its aging patriarch, Samuel Keller, remains chairman, and the board might need refreshment. Could Caroline, working alongside her ally Henri and maybe other board members, build the coalition needed to drive the strategic change Léman requires? Or would she find herself without the influence to move a set board, exposed instead to legacy issues and a possible conflict of interest with her own company? As Caroline’s first appointment to a major board, her decision also carries a signaling dimension; the boards that a rising executive chooses to join, and how visibly she vets them, shape how the market will read her judgment for years to come. The case gives students a realistic, decision-forcing vehicle for weighing a directorship’s opportunities against its risks: What due diligence a prospective director should conduct, how to assess whether one can genuinely influence and ally with fellow directors, and how a first major board appointment signals character and judgment to the market.

Summary
BARCELONA, JANUARY 2023. What started in 2016 as a humble entrepreneurial attempt to contribute to a more sustainable future had turned into a solid eyewear brand present in major Western markets. François van den Abeele was even more excited by the rapid development of the Sea2see Foundation, which he set up in Ghana. But success brought its own new questions and issues. From the start, he had relied on the superb craftmanship and dedication of an Italian frame manufacturer. Over time that relationship had turned into a mutual dependency: He was now one of its major clients but, reciprocally, had developed a key supplier risk. What if something happened to that relationship? Should he develop a broader set of suppliers and, if so, how could that be done without antagonizing a great working relationship? Recycling very much set the stage for the brand’s sustainability claims, but it also took massive amounts of time to manage. As other companies started to develop their own fishing net recycling supply chains, did it still make sense to invest so much time in the upstream phase or should he pour his energy into his beloved brand? Finally, maybe it was also time to revisit the growth/profitability dilemma and open up the capital to increase the speed of growth, all for the benefit of the environment as impact fed on scale.
