Company Summary

XStor provides cloud-based solutions for medical image and healthcare big data management, storage and distribution. Currently this information is locked in proprietary systems; thus collaboration across enterprises and geographies is very difficult leading to expensive and sub-optimal patient care. XStor solves the problem by making patient information securely available in realtime, anywhere on any device, to hospitals, clinics and physicians.
