Cyan Investment Management is a Melbourne-based boutique fund manager co-founded by Dean Fergie, running a single, deliberately narrow strategy: the long-only Cyan C3G Fund, focused exclusively on ASX-listed small and micro-cap companies with market capitalisations roughly between $50 million and $200-300 million. The firm avoids resources, biotechnology and other pre-revenue speculative sectors, instead emphasising companies with demonstrable revenue growth, using quarterly cash-flow disclosures to assess financial health where traditional earnings metrics are unreliable. Cyan prides itself on close, direct relationships with its (often high-net-worth) investors, offering regular reporting and monthly liquidity. Fergie's philosophy of doing 'one thing well' has produced a long-running, tightly focused track record in Australia's under-researched micro-cap segment.
