About

Unlearn.AI generates digital twins of clinical trial patients — AI models trained on historical trial data that predict how a specific patient would have responded as a placebo control. By supplementing small placebo control groups with these digital controls, pharmaceutical companies can run trials with fewer placebo patients (or none at all), reducing participant burden, trial costs, and development timelines without sacrificing statistical validity.

About

a2z Radiology AI has developed a whole-body CT analysis platform that simultaneously screens for over 24 medical conditions across a single CT scan, including incidental cancers, coronary artery disease, aortic aneurysm, bone density loss, and organ abnormalities. The AI acts as a second reader that radiologists can use to catch incidental findings that fall outside the primary reason for a scan — a major source of missed diagnoses.
