We Develop Game-Changing Solutions

ClairVista develops transformational technology solutions for delivering products or services with greater efficiency.

We developed Live Expert with a singular vision – to enable live consultation services across all forms of digital commerce (websites, email, kiosks, mobile devices) with one unified service platform. Live Expert, backed by three U.S. patents, is the most advanced and comprehensive system available for video chat services.

Prior to developing Live Expert, ClairVista helped McDonalds develop the Redbox DVD rental business (since acquired by Coinstar), which has grown to over 50,000 installations and $2.5 billion+ in annual revenue.
