KINGSTONE Investment Management is expanding beyond real estate into infrastructure through the establishment of KINGSTONE Infrastructure Investments, a joint venture with ADVENTRA Asset Management targeting institutional capital.
The new platform, known as KII, will develop and manage infrastructure investment vehicles focused on assets considered important to economic and societal resilience. Its target sectors include energy and heat supply, energy storage, mobility, digital infrastructure, security of supply, defence-related infrastructure and civil protection.
Germany will be the platform’s principal investment market, supplemented by Poland and the Netherlands, where the partners already have a local presence. KII will be led by Managing Directors Friedrich von Carlowitz, Karsten Mieth and Maximilian Radert.
“Alongside real estate, infrastructure is becoming an increasingly important asset class for many institutional investors. We are responding to this shift and believe that it presents significant opportunities for our firm,” said Dr Tim Schomberg, CEO and founder of KINGSTONE Investment Management. “Establishing a dedicated infrastructure business is therefore the logical next step for KINGSTONE.”
The launch broadens KINGSTONE’s investment management activities at a time when European infrastructure requirements are increasing across energy systems, digital networks, transport and security. The partners intend to offer institutional investors access through a range of investment structures rather than concentrating on a single fund or strategy.
“Our ambition is to build a long-term infrastructure platform with a clear focus on resilience-related investments and investment solutions,” said Philipp Schomberg, Executive Partner and founder of KINGSTONE Investment Management. “With Karsten Mieth, Friedrich von Carlowitz and Maximilian Radert, we have brought together a management team with extensive experience in this field.”
ADVENTRA specialises in institutional infrastructure and real asset investments, with particular experience in energy, storage, security of supply and resilient infrastructure. Its founder and Managing Partner, Karsten Mieth, has more than 30 years of experience in regulated fund management and real assets.
“Germany and Europe face enormous challenges in delivering future-proof infrastructure and strengthening the resilience of their economies,” Mieth said. “Systemically important projects are becoming increasingly interconnected and complex and require private capital alongside public funding.”
Mieth also pointed to changes in the investment environment that are making infrastructure increasingly accessible to institutional investors, including more established valuation practices and a clearer regulatory framework.
Before establishing ADVENTRA, Mieth was spokesperson for the Management Board of Encavis Group, where he was responsible for institutional asset management. Encavis operates photovoltaic and onshore wind assets across Europe.
Friedrich von Carlowitz has been Managing Director of KINGSTONE Capital Advisory for approximately two years and previously gained infrastructure experience at Macquarie. Maximilian Radert’s background includes developing domestic and international fund structures, analysing infrastructure markets and structuring investment solutions for institutional capital.
The establishment of KII represents a diversification of KINGSTONE’s investment activities beyond its established property business. Rather than focusing exclusively on conventional infrastructure, the platform intends to position resilience as its central investment theme, covering assets supporting energy independence, supply chains, digital systems and security-related infrastructure across its three target European markets.
