Prosperus Invest

Prosperus Invest was founded in 2010 in Zagreb as a growth equity and private equity fund manager focused on expansion-stage SMEs across Croatia and the broader Adriatic region. Led by Joško Miliša and Partner Luka Orešković, the firm has grown assets under management approximately 4× to around €200 million. Its flagship Prosperus Growth fund (first close ~€50 million, backed by EIF and HBOR under the CROGIP program) commits at least 75% to Croatian SMEs in IT, hospitality, renewables, healthcare, and publishing, with notable investments including IntechOpen (scientific open-access publishing, Rijeka) and Neos (data analytics and cloud IT services).
