Who we are
G4 is a boutique “invitation-only friends and family” office that manages the investments of a select group of people to the tune of some €40 million. We are constantly on the lookout for new investment opportunities.

Since 2011, we have invested in 70 projects across a variety of asset classes (equity, real estate, venture capital funds, start-ups, debt, and passive investments), for the most part in Slovakia.

Starting in 2016, we concentrated on two areas in particular – technology and real estate. We are a modest co-investor in UIPATH, Central Europe’s most successful tech company, which was valued at $38 billion at its NYSE IPO in April 2021.

Since 2021, our primary focus has been on investing in global technology blockchain funds. (www.g4-friends.com.cy)
