## Executive Summary

Reken has moved out of stealth: the Reken Platform and Northstar, its first application, are now available through an Early Access Program. The platform is an on-device security subsystem, the Private Core, that pairs locally run AI models with human-verification telemetry, and Northstar applies it to actively block phishing, business email compromise, account takeover, and other AI-enabled social engineering inside email, direct messages, and group chat. The team remains the defining asset: co-founders Shuman Ghosemajumder and Rich Griffiths built AI defenses for major banks at Shape Security, and Ghosemajumder founded Google's trust-and-safety product group. The public record still names no customer, price, or attestation, so the products are real but adoption is unproven.
