In this conversation, Josh walks through the path that led him there, from being born in Hong Kong and moving to Toronto as a child, to studying electrical engineering and starting his career at Toronto Hydro, where he saw firsthand how difficult it is to operate the grid in practice. That experience led him to found Opus One, an early platform for modeling and managing distributed energy systems that was later acquired by GE. After the acquisition, Josh found himself returning to the same core problem that had defined much of his career: the grid is becoming more complex, but the tools used to understand and operate it haven’t kept pace, ultimately leading him to start ThinkLabs. He also speaks candidly about the personal side of his journey, including the mental health challenges he faced after his first company, and reflects on what it means to start over while tackling one of the most critical bottlenecks in modern energy.
