vi is a contextual video platform. We connect publishers, content providers and brands through video storytelling. Video inventory is lacking, and users are hard to captivate. So our tools use contextual matching to create compelling video experiences on desktop, mobile and CTV. vi offers a full suite of self-serve tools: a video syndication engine powered by machine learning, a video ad server and an SSP. vi is trusted by over 35,000 publishers to deliver millions of contextual video stories every day.
