Live Nation, the world's largest live entertainment company, used Atlas to promote Madonna's 2015 "Rebel Heart" tour globally. With many concertgoers using mobile to search for tickets but switching to computers to buy, it was difficult for Live Nation to target mobile audiences and measure mobile ad success. Atlas' people-based capabilities allowed Live Nation to attribute a 66% increase in ticket purchases to mobile ads, including from the dating app Grindr, showing ads reached the right audience. This helped Live Nation understand mobile marketing effectiveness for future campaigns.
