Company History

Stiernbrandt AB is established since 2009. Our company is committed to create and develop high-tech innovations with focus, precision and passion. This commitment proves to meet a need among product developing companies in various areas e.g. biotec and industrial-tech companies.

Stiernbrandt AB has, among other projects, developed the electronics and software for the companies below:  

The founders of Stiernbrandt AB brought two patents valid in Sweden and in the US, into the company. First the amplifier High-End Power Amplifier ZS50 and second, for an ever better sound, the Stereo PreAmplifier ZP1. Both of these High-End audio products are built with the same technique and are a part of the so called Z-Series.

Further patent is achieved in 2009 when ReLiif®Duvet is patented in Sweden. ReLiif®Duvet and duvet cover is a smart product series which offer more comfort and warmth than an ordinary duvet or comforter. The product line is ready for the market in 2010. Now ReLiif® Duvet is tested and ready to launch. Our company establishes contacts with manufacturers in Sweden and abroad. In 2011, ReLiif®Duvet is patented in the US.
