A Sandbox is a place where ideas and prototypes can be put in front of end users (patients, caregivers, clinicians) on a regular and repeated basis for feedback, a place where solutions can be clinically validated and solutions can be piloted in both simulated clinical settings and real-world settings. We work with clients to solve the big health problems that require not just singular scientific advances but design for the complexity of human health. Our multidisciplinary team and access to a connected suite of prototyping and testing settings allow us to unite people-centered design thinking, a rigorous understanding of human behavior in context, and state-of-the-art biomedical and information technology.
