Our identity
Our Roots
Our History
Founded in 2010 as a product startup in Dortmund, we have undergone a transformation or two ourselves (in addition to various moves). In the beginning, we were only a service provider for "apps", which were brand new at the time, but soon we also developed the appropriate backends inhouse.
With apps for live TV productions, we then also ventured steps into the emerging "cloud" technologies, pushing not only us but also the cloud operators to their limits. Shortly after, we connected the first washing machine for a well known German company in 2014. The next step began with our involvement with a start-up from Düsseldorf: approached as a pure trade fair app development, we soon found ourselves in the middle of building an electronics lab to bring the Toniebox to life.
A steady growth, both in terms of workforce and customers, made us a modern service provider and consultant with our own products and a broad solution portfolio in 2019. This also convinced Vodafone GmbH, which acquired 100 % of our shares as of January 1, 2020.
Our goal: Connect your products.Management Team
