Product-as-a-Service Strategists design business models where products are offered as services rather than sold outright, enabling circularity through reuse, maintenance, and lifecycle management. They develop subscription or usage-based models that enhance customer engagement and resource efficiency. Their role is critical in transforming traditional business models into sustainable and recurring revenue systems. With growing interest in circular economy and service-based models, demand for such expertise is increasing globally. Professionals must combine business strategy, customer experience design, and sustainability knowledge to implement scalable and profitable service-based solutions.
