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.
The headquarters in Sarstedt serves as the central hub for Tellonym's operations, including software development, product management, user support, marketing, and strategic decision-making for the global platform.
Specific details about notable HQ facilities are not widely publicized, but it is expected to be a modern office environment conducive to a tech startup, fostering collaboration and innovation.

Emphasis would be on teamwork and adapting to the evolving social media landscape.
The Sarstedt headquarters is significant as the birthplace and primary operational base of Tellonym, from where its global reach is managed and its core technology is developed and maintained.
Tellonym is a globally accessible application available on iOS and Android platforms, and as a web application. It supports multiple languages, catering to a diverse international user base across numerous countries. Its core functions, such as anonymous Q&A, messaging, and profile interactions, are supported worldwide, enabling communication across geographical boundaries. While the operational headquarters are in Germany, the platform's reach and user community are international.
