Strategy
Real Assets
AUS
Our Real Assets strategy targets high-quality, long-duration assets with stable cash flows and inflation-linked returns.

Strategy
Private Equity
AUS

- Average hold period of 5–7 years
- Investments across 15+ countries

Co-Investments
Direct co-investment alongside leading global private equity sponsors, providing fee-efficient exposure to high-conviction opportunities.
Secondaries
Purchases of LP interests and direct assets in the secondary market, providing liquidity solutions and portfolio construction flexibility.
Strategy

Opportunistic investments in stressed and distressed corporate debt, targeting situations with clear paths to recovery or restructuring.
Special Situations

Our Differentiators
What Sets Aspis Partners Apart
In a crowded alternative investment landscape, Aspis Partners stands apart through four core competitive advantages built and refined over two decades of global investing.
