Investment thesis

Aternus manages and invests its founders' assets where it sees the highest potential returns, while also weighing positive social impact. Its current portfolio is concentrated in private equity, real estate and venture capital funds focused on technology, marketplaces, SaaS, fintech and deep tech, with a smaller allocation to equities and bonds. The firm emphasizes the idea, strategy, communication and above all the quality of the people behind each fund or project. For exceptional, high-potential opportunities it co-invests alongside PE and VC funds, supporting portfolio companies not only with capital but also with expertise in HR, sales, marketing and business strategy.
