From Berlin to the world, we're empowering developers to create experiences that truly connect with their users.
It started with a simple frustration: why was it so hard to deliver personalized experiences without building complex infrastructure from scratch?
In 2025, our founders were working on a project that needed real-time content personalization. After weeks of building custom solutions, they realized other developers faced the same challenge. The idea for Usertune was born in a small café in Berlin's Mitte district.
Today, we're a team of passionate engineers, designers, and product enthusiasts who believe that personalization should be accessible to every developer, not just tech giants with unlimited resources.

To democratize personalization technology, making it as easy to implement as adding a line of code.
"We believe every user deserves a personalized experience, and every developer should have the tools to deliver it without the complexity."
