What Keyri does

Keyri helps companies implement simple, secure anti-fraud and authentication solutions to delight users and keep bad actors off their platform. Keyri's mobile application and browser fingerprinting suite ties user identities to trusted devices, preventing fraudulent activity such as account opening, account takeovers, bot attacks, and referral/promo abuse. Keyri is able to establish an immutable device fingerprint for every device, alerting companies of any suspicious devices during sign up, log in, or subsequent authentication events. Keyri also offers a passwordless authentication suite that leverages Passkeys, WebAuthn, and QR codes to enable biometric authentication on all platforms and devices, providing a seamless user experience, strengthening multi-factor account security, and reducing reliance on other tedious and unsecure authentication methods.

Secure fraud prevention and authentication platform

What is your company going to make? Please describe your product and what it does or will do.

We build a fraud prevention and authentication platform that helps companies detect and stop fraudulent activity by tying user identities to trusted devices. Our product combines a mobile app and browser fingerprinting to create an immutable device fingerprint, preventing account takeovers, fake signups, bot attacks, and promo abuse. We also offer a passwordless authentication suite using Passkeys, WebAuthn, and QR codes to enable biometric login across devices without relying on passwords.

Where do you live now, and where would the company be based after YC?

We live across San Francisco and remote locations. Post-YC, the company would be based in San Francisco, CA, where the core team is located.

Explain your decision regarding location.

We chose San Francisco because that's where the founders live and where the company's main operations and early customers are. Being in SF allows us to connect directly with our target B2B customers and security ecosystem.
