ZOUNDR – Suite of Apps for Musicians (Germany)
An integrated platform offering musicians a suite of connected web apps under one SSO account. It includes an e-learning app for music and production, a copyright issuing system, and a virtual networking app similar to Hyhyve, providing creators with versatile digital tools.

The Challenge
Musicians in Germany lacked a unified digital ecosystem. Learning music production, protecting copyright, and networking with other artists each required separate platforms with no interconnection. Manuel Kellner, co-founder of ZOUNDR, wanted to build the all-in-one hub that the music creator economy was missing.
The Solution
We built the entire ZOUNDR app suite — three interconnected web applications under one SSO account. The e-learning app lets musicians learn production and theory; the copyright system lets creators register and issue rights to their work; the networking app connects artists in a virtual, community-driven space similar to Hyhyve.
- Single Sign-On (SSO) account connecting all three apps seamlessly
- E-learning platform with music production and theory courses
- Copyright registration and certificate issuance for original works
- Virtual networking space for artists to connect and collaborate
- Creator profiles with portfolio, discography, and social links
- Cross-app notifications and unified dashboard
