About Whiterabbit.ai

Whiterabbit.ai is a venture-backed artificial intelligence company based in Silicon Valley that specializes in transforming breast cancer screening through advanced AI technology. The company's mission is to make late-stage breast cancer a rarity by detecting it early through the power of AI, revolutionizing the screening paradigm by removing barriers to adoption and enhancing collaboration between artificial and human intelligence. Founded by executives with deep operational experience in radiology—having owned and operated 9 outpatient radiology sites—Whiterabbit brings a unique understanding of clinical workflows and constraints. This operational DNA informs their product development approach, ensuring solutions integrate seamlessly into existing clinical environments. The company's commercially available products, WRDensity and WRRisk, leverage a proprietary dataset spanning more than 2 million patients and 11 million datapoints. These AI-powered tools address critical challenges in breast imaging including mammographic density assessment and cancer risk stratification, helping to address the critical shortage of radiologists while improving clinical outcomes, optimizing patient experience, and reducing healthcare costs. Whiterabbit collaborates with leading academic and professional institutions including Washington University's Mallinckrodt Institute of Radiology, Stanford University, Guardant Health, and RadNet. The company's team comprises over 30-50 AI scientists, engineers, and healthcare professionals dedicated to advancing early detection and improving diagnostic accuracy in breast cancer care. Led by CEO Alexander Sardiña, MD, a physician with extensive experience in early detection, Whiterabbit continues to advance its mission with several patents pending and products in development.
