Nucleus is a technology solution that was founded in 2014 at Harvard University. It offers an end-to-end solution for retailers and other brick and mortar businesses by capturing and providing previously unaccessed data through its proprietary blockchain and real-time sensor technology. The solution includes ION Sensors deployed in 10 live retail establishments, creating a valuable data network for unique visitor IDs and corresponding user data. Unlike other technologies, Nucleus's IoT sensor technology does not rely on RFID, WiFi, Bluetooth, or facial recognition.
