Reimagining access to private markets
Openstone opens up access to institutional-grade funds in private debt and real estate private equity, until now reserved for institutional investors and the very wealthy.
Multi-manager selection applied to private assets
Accessible minimum tickets for broader diversification
From €100,000, private clients can build a diversified portfolio of several institutional-grade funds.
Partnerships with leading global managers
Openstone has privileged access to the world’s largest private-markets managers. Each one manages tens of billions of dollars in assets.
A proprietary selection methodology known as “M3”
Under the leadership of our Chief Investment Officer, Patrick Jenvrin, who has 35 years of investment experience, Openstone has developed a proprietary methodology known as “M3”: MULTI-manager, MULTI-strategy, MULTI-vintage.
Investment in unlisted assets requires a long-term investment horizon and carries risks (capital loss, illiquidity). Non-contractual content that does not constitute personalised investment advice.
