Born from a frustrating night of updating social-media bios, Linktree is a Melbourne-founded platform that gives creators, brands and businesses one link for sharing their online content. Brothers Alex and Anthony Zaccaria and business partner Nick Humphreys launched its first version in 2016 while running the digital agency Bolster; today, the company says more than 70 million people use it worldwide. Linktree has grown beyond link sharing to help users understand their audiences and earn from digital content, while remaining headquartered in Melbourne with offices in Sydney, San Francisco and Los Angeles.
