CTO & Co-Founder (Equity-Based)Help us build Shadow — your other version.
About ShadowShadow is an AI-powered emotional companion that acts like a non-clinical psychologist in your pocket — a presence that listens, reflects, and helps people navigate emotional challenges without pressure or medication.
Born from lived experience in a conflict zone, Shadow was created for the moments where traditional support isn't accessible or immediate — when people need understanding more than solutions.
It's a new category of mental health support: grounded in therapy principles, enhanced by AI, and built for real-world use.
Our mission is to redefine how mental health care is experienced — combining psychology, storytelling, and cutting-edge AI to offer quiet, reliable, deeply human support through technology.
