k-ID is the global leader in privacy-first compliance and age verification infrastructure. Recognized as one of TIME’s Best Inventions of 2025, named a Tech Pioneer by the World Economic Forum and a winner of Fast Company’s Next Big Things in Tech, we are building the Age Layer for the internet—the fundamental infrastructure that allows digital platforms to verify age and manage compliance globally without friction.
Our core platform, anchored by the Compliance Development Kit (CDK) and AgeKit, is the trusted engine for the world’s largest game publishers and digital ecosystems. We replace fragmented, manual compliance with a unified API that handles age verification, parental consent, and regulatory logic across 200+ markets. Backed by top-tier venture capital firms like a16z and Lightspeed, k-ID is entering a phase of growth to define the standard for global digital safety.
