AI has made faces, voices, accounts, and entire interactions easy to fake. Helix is rebuilding the trust layer of the internet: giving banks, marketplaces, communication platforms, and digital services a fast, privacy-first way to know there is a verified human on the other end. Helix uses a short, randomized voice challenge to confirm a live, unique, account-bound human in about two seconds with 99%+ accuracy. The challenge is designed to resist replay, cloned voices, and deepfake injection. Processing happens on the user’s device, with no additional app, SMS code, ID upload, selfie, or stored voice recording. Unlike identity checks that prove someone once at signup, Helix can be invoked throughout the digital relationship—before a call, message, transaction, account recovery, age-gated action, prescription, or other high-trust event. It integrates with existing identity, fraud, and trust-and-safety systems to route humans and bots in real time through one signal: human, unique, authenticated. Helix is built by operators whose prior platforms blocked more than 100 billion bot attempts, protected over $50 billion in ticket sales, and helped power more than 97 billion matches worldwide.
