Company Overview
Experienced Team with Institutional Background
Icosa Investments was established in Switzerland in 2023 by a team of experienced professionals with longstanding backgrounds in alternative fixed income, catastrophe bonds, institutional distribution, and client relationship management.
The team’s experience spans leading international financial institutions and specialised investment platforms. That background informs the firm’s emphasis on quality, technical depth, and long-term institutional relationships.
With backing from strategic industry partners and key investors, and as a firm chiefly owned by its employees, Icosa Investments combines entrepreneurial spirit with close alignment of interests and a clearly institutional orientation.
Founder’s View
“Professional and institutional investors in Switzerland are often interested in asset classes characterised by clearly identifiable risk drivers, quantifiable risk profiles, and institutionally relevant considerations. In that context, data, scientific methods, and disciplined processes can be important prerequisites for a well-founded understanding of such markets.”
Florian Steiger, CEO & Founder
