Founded2016

Tellonym is a popular social networking application that allows users to send and receive anonymous messages, often in a question-and-answer format. Launched in 2016, it gained significant traction among teenagers and young adults by providing a platform for candid feedback and curiosities without revealing the sender's identity. Users create profiles and can share a link to their Tellonym inbox on other social media platforms, inviting others to send them 'Tells' (anonymous messages). While fostering open communication, the platform also continually works on features to promote safety and combat cyberbullying, a common concern with anonymous platforms.
