Linktree is a freemium social media reference landing page developed by Alex Zaccaria, Anthony Zaccaria, and Nick Humphreys, headquartered in Melbourne and Sydney, Australia. Founded in 2016, it serves as a landing page for a person or company's entire associated links in social media, which rarely allows linking to multiple sites. The site was inspired by the developers' annoyance with social media that can't allow multiple hyperlinks.
