Max Rellin, Tellonym: 6 Million Monthly Users at Age 21
About this episode
The Young Founder Behind Tellonym
Max Rellin is just 21 years old and already the founder and CEO of one of the most successful anonymous feedback apps: Tellonym. What started as an idea has evolved into a platform used by more than 6 million people monthly – with teenagers particularly embracing the app.
Dropping Out for the Big Dream
The path to success wasn't without risk. Max was studying Computer Science but made the conscious decision to drop out of university to focus entirely on Tellonym. It's a decision that has paid off: the anonymous feedback app has spread rapidly among young people and continues to expand into new markets.
Growth and International Expansion
Currently, a team of approximately 10 people works daily to achieve new growth targets and make Tellonym even more well-known. International expansion is a key focus – the app is conquering new countries and steadily building its user base.
The numbers speak for themselves: 6 million monthly users is an impressive result for a young startup. Particularly noteworthy is the strong resonance among the teenage demographic, who use Tellonym as a platform for anonymous feedback.
Networking in the Startup Scene
Max isn't just a successful entrepreneur but also well-connected in the German startup scene. He's part of YEP, the network for young founders jointly led by podcast host Fabian Tausch and Thomas Bachem, Chancellor of CODE University of Applied Sciences. This networking enables exchange with other young founders and valuable mentors.
Tellonym: Anonymous Feedback for Generation Z
Tellonym has identified and successfully filled a market gap. The app allows users to give and receive anonymous feedback – a concept that particularly resonates with young people. In an era where social media is often characterized by fear of judgment and public criticism, Tellonym provides a protected space for honest opinions.
Lessons Learned for Young Founders
Max Rellin's story demonstrates that age is no barrier to entrepreneurial success. At 21, he has already proven that courage, vision, and hard work can pay off. Dropping out was a calculated risk that paid off through his focused commitment to his own company.
For other young founders, Max serves as an inspiring example of how the right idea at the right time can achieve great success. Tellonym shows how important it is to understand your target audience's needs and develop a solution that's truly needed.
