Malcolm Nogueira and Gustavo Ozório, Brazilian alumni of the 2025 Aspire Leaders Program, have been selected to advance to the second phase of the Global Sustainability Challenge (GSC), an initiative led by the Stanford Doerr School of Sustainability, with their impact-driven project SolarLink.
College classmates, Malcolm and Gustavo encouraged one another to apply to the Aspire Leaders Program, recognizing it as an opportunity to strengthen their leadership skills and turn ideas into real-world impact projects. Throughout their Aspire journey, both developed a stronger critical perspective, expanded their knowledge, and gained access to tools that proved essential not only for shaping their initiative but also for navigating the path to the GSC.
The Global Sustainability Challenge brings together students from around the world to create, test, and present practical solutions to sustainability challenges. The program offers mentorship from international experts, intensive workshops, methodological support, and access to a global network of universities and talent. Over the course of the program, projects evolve from early concepts to prototyping and real-world validation, culminating in presentations before panels composed of representatives from institutions such as Stanford and Zhejiang University. Finalist teams compete for funding of up to $10,000.
According to Gustavo, the connection between Aspire and the GSC was decisive in bringing the project to life.
All of this was only possible because, through the Aspire Leaders Program Brazil and the Aspire Institute, I gained access to this global network and discovered the Global Sustainability Challenge itself — a connection that opened doors, provided references, and gave me the confidence to turn this idea into reality.

Malcolm and Gustavo’s team includes four additional members and emerged from a shared concern about the growing challenge of energy insecurity and the high costs of accessing electricity. In response, the group founded SustainEdge, the organization through which they developed SolarLink — a solution designed to strengthen small businesses through the co-creation of shared microgrids. These systems rely on minimal battery usage and are powered by solar energy and other clean sources suited to local contexts, such as traceable biogas or micro-hydropower.
Rather than requiring each user to individually bear the high costs of diesel or deal with the instability of conventional power grids, SolarLink organizes mixed-use energy clusters. In these arrangements, staggered energy demands naturally smooth load curves, reducing the need for energy storage, lowering carbon intensity, and increasing overall system efficiency.
The solution also includes a simple application featuring green, orange, and red pricing bands, indicating when energy is cheapest, cleanest, and most abundant. In parallel, a transparent accounting system fairly distributes costs among participants and facilitates access to financing models such as pay-as-you-save schemes and green loans linked to corporate social responsibility (CSR) initiatives.
Currently, SustainEdge is in the second phase of the GSC, focused on prototyping, solution validation, and preparation for the Americas Regional Final. Participation in the challenge represents a significant opportunity for social impact and reflects Aspire’s role in strengthening collaborative pathways and developing leaders committed to transforming realities.
