Chui, now operating as Trueface (part of BigBear.ai after the Pangiam acquisition), is a facial recognition and computer vision company. Originally launched as "Chui," the world's first faceprint API for access and identity, the technology is delivered today as a licensed developer SDK with C++, Python, Android, and iOS bindings, plus a Dockerized on-premises REST API (Trueface On-Prem / PTOP) for 1:1 and 1:N face matching, spoof and liveness detection, object detection, and identity verification. Deployment options span on-device, self-hosted Docker, and AWS. The technology has been evaluated in NIST FRVT and DHS/CBP testing and is applied across fintech, education, security, healthcare, retail, hospitality, and government. Surfaced as a 500 Global portfolio company and profiled by the API Evangelist network.
