Aionis is a private investment company. We invest proprietary capital across public and private markets.
We invest with conviction and a long-term perspective, combining engaged judgement with discretion and hands-on support. Our approach reflects an ownership mindset shaped by prior experience across leading private equity and public market firms.
Long-term positions in listed businesses we understand, combining two complementary approaches: transformation cases, where a clear catalyst — strategic, operational, or governance — can unlock value; and quality compounders acquired at fair valuations. We remain agnostic across developed markets, adapting our balance between the two as the macro environment evolves.
Selective, hands-on partnerships focused on family and founder succession situations and corporate carve-outs across Europe, with a particular focus on the DACH region. We can act as a majority or minority owner and long-term steward of businesses.
If you are interested in our approach or want to discuss ideas, we would be glad to hear from you.
