Reality Defender, one of several startups developing tools to attempt to detect deepfakes and other AI-generated content, today announced that it raised $15 million in a Series A funding round led by DCVC, with participation from Comcast, Ex/ante, Parameter Ventures and Nat Friedman’s AI Grant.

The proceeds will be put toward doubling Reality Defender’s 23-person team into the next year and improving its AI content detection models, according to co-founder and CEO Ben Colman.
