The overall investment objective is capital generation, achieved through precise risk-adjusted returns, with a pre-determined risk / volatility coefficient, whilst maintaining a focus on operational costs. Gardenia’s Investment focus is to acquire positions in Seed and/or Series A stage private companies, who provide a clearly defined, innovative, and disruptive solution to a predefined need within the financial services, trading, and similar industries. Our bias is towards financial technology platforms, data analytics and algorithmic IP investments, where we have already made significant successful investments.
