Company Profile

Gastauer Family Office (GFO) is a single-client private asset management firm dedicated to managing the substantial asset structure and the financial and personal affairs of the Gastauer Family. With over US$11.4 billion in assets under management, GFO employs global hedge strategies and maintains a broad mandate to trade and invest across various global markets and financial instruments. The firm's investment approach is driven purely by the needs and preferences of the Gastauer Family.

The firm was established in 2008 by its Chairman and Founder, Michael Gastauer, a German billionaire entrepreneur and investor. Gastauer's career began at the age of 24 when he founded his first company, an asset management firm in Zurich, which quickly reached a significant valuation and was later sold to a Swiss investment firm. In the early 2000s, he pioneered an online payment system for eCommerce, achieving a US$480 million valuation before its sale in 2008. Seven years later, Gastauer became an investor and founder of a digital banking group, Black Banx, which rapidly grew to a US$9.8 billion valuation by 2018, becoming one of the fastest-growing FinTech companies in Asia.

Gastauer Family Office has a dedicated venture capital arm that actively invests in FinTech companies, reflecting Michael Gastauer's extensive background and success in the financial technology sector. Beyond its core investment activities, GFO demonstrates a strong commitment to philanthropy through the Gastauer Nature Fund. Established in January 2024 with an allocation of $1.5 billion from the family's fortune, this fund aims to combat mass extinction, protect vital ecosystems, and safeguard at least 30% of land and ocean areas by 2030, aligning with global conservation goals. The fund supports local partners in securing land ownership in protected areas and strengthening their management.

The firm's investment activities span a global reach, with a particular focus on financial services, technology, and impact investing. Its venture capital arm targets various stages of FinTech companies, from seed to growth rounds. Michael Gastauer, as the sole identified key decision-maker for the family office, brings a wealth of entrepreneurial experience and a proven track record in building and scaling successful financial technology ventures.
