CartLatch

CartLatch is a web + mobile checkout layer that lets shoppers pay in one tap across participating merchants using a single, tokenized payment profile. Instead of forcing users to create yet another merchant account, CartLatch provides a lightweight “Pay with CartLatch” button that merchants can add via a plugin or simple API. Shoppers verify once (passkey/biometric), choose shipping details, and then reuse them everywhere CartLatch is supported. The product focuses on reducing checkout abandonment for small and mid-sized ecommerce brands that can’t build world-class checkout UX. It includes a merchant dashboard showing conversion lift, drop-off points, and A/B testing for the CartLatch button placement. It’s a traditional app with a small AI component for fraud/risk scoring and anomaly detection, but it’s not “AI-first” because payments success depends on reliability, not gimmicks.
