With his own company Wilhelm Perfume he designs olfactory signatures for brands, creates custom perfumes or creates fragrances for artists to be used for installations or exhibitions.

In 2017 Andreas created the GENESIS olfactory signature for Hyundai and created the scented part of Shirin Yousefi's KADINST award winning installation 'Tales of Cortex'.

He is part of the 'Scent Festival' in Switzerland where he makes his debut with his first own art project: the smallest or most intimate fragrance installation ever seen.

An olfactory punk, he recently launched his own line, perfume.sucks. At perfume.sucks, the whole formula is written on the bottle: a kind of open source project, with its always sarcastic eye firmly on the industry.
