about

We believe that every interface should light up the user’s life. Since day one, our mission has been clear: to craft the perfect user interface for your apps and business needs. With a strong focus on adding a new layer of user experience using design, innovation, and AI, always keeping humans in the loop, now an AI-driven team, we are dedicated to delivering dynamic, scalable, and human-centered digital tools.

Founded in 2014, we started by collaborating with OutSystems, helping improve their Silk UI framework. Over the years, we’ve expanded our expertise in UX/UI design, front-end development, full delivery of open-source solutions, and building AI agents to build your interfaces.

"Hi Interactive worked with Colliers to develop a B2C and B2E design system. The system has allowed us to bring consistency to all our applications built on OutSystems and has removed the need for extensive design on each project."

Simon Chester Director, Digital Agency @ Colliers

"Hi Interactive exceeded our expectations, the project managers, supervisors, and support teams of both application and UI/UX developers were all a pleasure to work with. They are instrumental in bringing our ideas to life using OutSystems."
