## About

Jürgen Jaron, Dieter Rein and Erhard Rein established Bellevue Investments in 1993 following exits from Magix and related software businesses. The multi-family office manages the partners’ capital from those transactions. The firm allocates across real estate, private equity and technology. Asset classes include European commercial and residential property, SaaS platforms, mobile applications and renewable-energy projects. It executes direct co-investments and SPVs rather than broad fund commitments. Confirmed holdings include Bitcoin Group SE and multiple Berlin properties at Gradestraße 40-50, Tempelhofer Weg 60 and Quedlinburger Straße 1. Geographic reach covers Europe and North America. Team size and total deployment remain undisclosed. Additional vehicles include the Bellevue Campus commercial asset and mixed-use holdings in Dresden. Russmedia Equity Partners acquired Magix Software GmbH in 2025. The office supports WWF Germany through separate philanthropic channels. Ownership stays with the founding principals and their designated board members. This closed structure limits external capital raises and keeps decision rights inside the original partner group.
