About us


Founder and Managing Director


Peter Jäderberg’s first company focused on institutional equity trading (NYSE) and quantitative analysis (1985 to 1991). The deep insights made him a convinced financial market skeptic and a supporter of niche and real assets. From 2004 to 2010, his then-company initiated and structured 28 international alternative investment projects in various niche assets and imple¬mented them as white label products for third parties. More than 1.5 billion Euros were invested in these projects. In 2009, he stumbled over the unique sandalwood project IN Australia, for which he founded the Jäderberg & Cie. group in 2010. Since 2018, he has evolved to an entrepreneurial impact investor, actively living the impact investing philosophy, Deep Impact, publicly and passionately.
