Reality Defender
Reality Defender is a New York deepfake detection company founded in 2021 by Ben Colman, Ali Shahriyari and Gaurav Bharaj. The company develops security software that detects AI-generated and manipulated media across images, audio and video for enterprises and government organizations. Its current products include RealScan for media analysis, RealAPI for developer integrations, RealCall for voice-channel protection and RealMeeting for communications environments. Reality Defender also provides APIs and SDKs that allow developers to integrate its detection models into other systems. The platform uses an ensemble of detection models rather than relying on a single classifier and continuously tests and updates those models as generation techniques change. Current company leadership includes Colman as Co-Founder and CEO, Shahriyari as Co-Founder and CTO, and Bharaj as Co-Founder and Chief of Research and Development. TechCrunch reported that the company began as a nonprofit before moving to outside financing as commercial demand for deepfake detection increased. Crunchbase identifies Reality Defender Inc. as an active for-profit company and confirms all three founders.
