Reken

Reken is an AI security company building a trust layer for the Internet to combat generative-AI-enabled fraud, phishing, scams, deepfakes, and automated social engineering. Co-founded by Shuman Ghosemajumder (who founded Google's Trust & Safety group) and Rich Griffiths, both formerly of Shape Security, Reken centers on the on-device Reken Private Core: the Reken Model Zero detection ensemble, the Reken Trust Sensor for verifying human activity, and an embedded Reken API that lets applications connect to the core while keeping data on-device with local AI models and zero AI token cost. Protected applications form the Reken Network, a self-assembling zero-trust mesh. The company is pre-launch, offering an Early Access Program; it does not yet publish a public developer API, SDKs, or documentation.
