Austrian startup Tumbleweed has successfully raised a record €6.9 million in a seed round, marking the country's largest investment in the space sector. Led by PactVC, the funding round saw participation from Vanagon Ventures, Prototype Capital, EWOR, and international investors. Co-founder and CEO Julian Rothenbuchner elaborated on Tumbleweed's mission to democratize microgravity research.
Founded in 2024, Tumbleweed operates from Vienna and Delft, developing modular laboratory Pods for use on its free-flying Oasis orbital platform. The company's first mission, Oasis Alpha, launched in July 2026, carried experiments for first-time space users, all booked a year in advance. Tumbleweed's Pods provide power, data connectivity, and infrastructure for conducting microgravity experiments.
Rothenbuchner, inspired by the concept of rolling tumbleweeds, developed a wind-driven Mars rover from a young age, leading to the founding of Tumbleweed. By simplifying the process of accessing microgravity, Tumbleweed aims to remove complex barriers for pharmaceutical and biotechnology companies, making it more accessible for research and development teams.
