About Tori S.
Operations executive with a track record for building the backbone of breakthrough companies. I specialize in designing operational infrastructure that empowers technical teams to innovate without friction and unlocks efficient scale for category-defining businesses. I am the Chief Operating Officer at Radiant, a Series C startup backed by a16z, DCVC, USV, ARK Invest, and others, with $226M raised to date. As COO, I lead all operations—biz strategy, finance, people, legal, supply chain, and factory ops—building execution infrastructure that keeps our engineering team unblocked as we scale to commercial production of the world’s first portable nuclear microreactor. Before Radiant, I led operations scaling strategy at Happy Returns, helping structure the company for its Series B and supporting its $350M acquisition by PayPal. Post-acquisition, I stayed on to operationalize their automation strategy, tripled warehouse capacity, and built a high-performance operations organization from the ground up. I honed my operational discipline at McMaster-Carr Supply Company, a multi-billion dollar industrial supply company renowned for execution and systems thinking. Over nearly a decade at McMaster-Carr, I rose through the ranks to lead teams of 900+ and developed deep expertise in high-efficiency logistics, process design, and organizational leadership.
