Summary
The case examines the entrepreneur-led carve out and buyout of dss+, DuPont’s safety and sustainability consulting division, by Gyrus Capital and dss+ management team. dss+ (formerly “DuPont Sustainable Solutions”) played a pivotal role in high-risk industries such as oil, gas, and chemicals, providing critical consulting services at a time when global regulatory pressure on operational safety and sustainability was intensifying. Gyrus Capital, a mid-market private equity specialist, came together with the management team to engineer the buyout, based on the firm’s strong and predictable revenue streams, long-term client relationships and specialized expertise in safety and sustainability consulting. What emerged out of the 2019 transaction was an independent sustainability consulting powerhouse with over 1,500 consultants around the world. By 2024, dss+ was still expanding rapidly in terms of staff and domains of expertise, not to mention geography, and had to respond to quickly evolving external and internal demands, with clients increasingly expected to be served globally on a full range of sustainability-related services. With a strong sense of purpose (saving lives and creating a sustainable future), a potent pitch line (Protect. Transform. Sustain), over 750 clients on 1,800 projects across 41 countries, a global team of 1,500 people and plenty of organic growth across 7 core industries, the company was clearly heading for the stars. Yet, new questions loomed: Was it time to start managing that wild growth, deepening competitive advantages and building functional moats? How would dss+ remain competitive? Was it time to put a few new initiatives on high octane fuel: Leadership? Digital transformation? Global growth? Some totally new ideas?

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.

Summary
The case focuses on Contabilizei, a Brazilian startup providing online accounting services for small and medium-sized enterprises (SMEs). The case study delves into the challenges faced by the company’s founder and CEO, Vitor Torres, as he navigated Brazil’s complex social and economic landscape. Issues such as Brazil’s byzantine tax system, disparate educational quality and accessibility, and the high cost of doing business in the country are explored. Despite these barriers, Contabilizei demonstrated impressive growth, transforming digital innovation into standardized services. However, the rise of competitors and persistent profitability concerns prompt Torres to thoroughly explore future strategies to maintain market leadership and improve financial performance. The case provides an in-depth analysis of Brazil’s entrepreneurial ecosystem, examining its business, educational, legal and infrastructural realities and their implications for startups as well as the difficult step for startups to become established companies.

Case reference: IMD-7-2540 ©2024
Summary
Terry Burns launched UniMag in 2007 and went on to develop its ecosystem of affiliated companies over several years. As most media were rapidly shifting online, UniMag established its brand as a high-profile magazine with a counter-intuitive focus on high-quality print and journalism. Since then, digitalization has increasingly shaped the media landscape, opening many opportunities for Burns. By 2023 digital activities most effectively drive the business of the many affiliated companies in UniMag’s ecosystem. In contrast, its print magazine sales have stalled, and costs keep growing. Burns and her team must make a strategic decision: What to do and what to stop? Where to perform and where to transform? In the context of a transforming media industry, the case illustrates how to set strategic direction in the face of disruptive forces in order to drive change and open opportunities.
