Sentinel to get $1.35 million from Jaan Tallinn, Taavet Hinrikus et all

Sentinel, a Talinn, Estonia-based cybersecurity SAAS developer, announced that it completed a $1.35 million capital investment round.

The money was provided by a range of investors from Estonia, including angels Jaan Tallinn, Taavet Hinrikus, Ragnar Sass, Martin Henk and the early-stage VC firm, United Angels VC.

Sentinel, founded in 2019 by Kaspar Peterson and CEO Johannes Tammekänd, develops tools to detect deepfakes via an AI detection platform used by governments, media and defence agencies for detecting disinformation campaigns, synthetic media and information operations.

The platform offers four layers of deepfake defence: an initial layer based on hashing known examples of in-the-wild deepfakes to check against (and which he says is scalable to “social media platform” level); a second layer comprised of a machine learning model that parses metadata for manipulation; a third that checks for audio changes, looking for synthesized voices, etc; and lastly a technology that analyzes faces “frame by frame” to look for signs of visual manipulation.
