Iterative Health is pioneering the use of artificial intelligence-based precision medicine in gastroenterology (GI), with the aim of helping to optimize clinical trials investigating treatment of inflammatory bowel disease (IBD). We use advanced machine learning and computer vision to interpret endoscopic images along with other types of data, helping clinicians to better assess patients with potential GI problems. This gives practitioners enhanced capabilities in the detection, annotation, disease scoring and treatment of GI related diseases. Iterative Health is initially applying these advances towards standardizing disease severity characterization for inflammatory bowel disease. Ultimately, the company aims to establish more meaningful endpoints to serve as better predictors of both therapeutic response and disease outcomes. The company is headquartered in Cambridge, Massachusetts.

At Improbable, we believe that simulations as large and complex as the real world are the next fundamental breakthrough technology. Like in the real world, objects in these simulations will change in response to their environment, and their interactions will combine to form massive, complex systems.

Our technology creates permanent, persistent and engaging experiences: worlds where your actions really matter. The same technology that makes imaginary worlds feel real can also illuminate complex systems at work in reality. We use insight acquired through simulation to solve real world problems.
