We are Gothenburg´s number one go-to company for high voltage battery assemblies, powertrains, prototypes and products. This is what we do.At Mattr we are doers. We love to build and to make stuff. We love to create new shiny things to challenge ourselves and the status quo. To challenge the perception of what can and can’t be done. It’s in our bones and in our culture. A culture of friendship. A culture of the power of the collective mind And the potential of cray-cray-genius go-my-own-way individualism.
