LATEST NEWS: The team is excited to announce that Openr Technology is joining a bigger family as part of a strategic acquisition. About Openr: Engage the engaged with Openr: When consumers are engaged with the content you share, they're much more likely to tune into your brand message. That's why we get an average 5% CTR. Get your slice of the action by using our platform to add messages to all the content that you share – on social, on email, even via paid-for distribution - and unlock the right action, at the right time, with the right audience. Integration is simple - rather than sharing an article or image with a normal URL on social or email, use an Openr link instead. Then when fans and followers click the link they'll see the content in all its glory but with the message and call-to-action too - encouraging further engagement and delivering tangible ROI on the content sharing. By closing the gap between content sharing and direct action Openr has already been selected by the Global Festival of Media for their start-up showcase in Rome; named a Must-Have Marketing Tool by Entrepreneur Magazine, and is being used by global brands and agency giants alike.
