⚡️ Hey you,

Today, JUST offers a plug-and-play checkout experience that combines a high-performance, fast checkout with marketing triggers, enabling merchants to increase revenues and margins by an average of 10-15%. With over 500 merchants onboarded in France and more than 1 million users, we’re now extending operations to the UK to drive innovation that will impact millions of consumers and brands worldwide. Yes, we’re on a mission to reshape the entire customer journey and make shopping simple, smart, and social.

Our ambition is to serve a new generation of consumers for the next several decades, as PayPal did 30 years ago. But our vision goes beyond checkout: we draw inspiration from social commerce innovations in China. We believe the future of shopping lies in seamless experiences that merge simplicity, personalization, and social interaction. This will empower consumers to make purchases effortlessly, track orders, receive fast refunds, enjoy personalized shopping experiences, and even engage in real-time shopping with friends. "Becoming the new standard of shopping for the next decades" isn’t just a tagline—it’s our commitment to the future.

Join us on our mission to make shopping simple, smart, and social.
