Austrian space technology startup Tumbleweed has secured €6.9 million in the country's largest spacetech seed funding round to date. Led by PactVC, the round saw participation from Vanagon Ventures, Prototype Capital, and EWOR. Founded in 2024 and operating across Vienna and Delft, the company develops modular laboratory pods that allow researchers to conduct experiments in microgravity without the need to build their own space infrastructure.
Tumbleweed's first commercial mission, Oasis Alpha, launched on July 7, 2026, carrying payloads for four first-time space users. Built in nine months, the platform provides fault-isolated containers equipped with power and data connectivity. This configuration allows researchers to monitor and control their experiments remotely, operating similarly to cloud computing infrastructure. The company's €15,000 offering covers the entire process, including the pod, launch services, and operational support.
Microgravity environments offer distinct conditions for materials science, protein synthesis, and pharmaceutical research. Researchers are utilizing the platform to explore accelerating the development of organoids derived from stem cells and to study biological changes associated with aging in the immune system. Tumbleweed is planning three additional missions for 2027, expecting to carry payloads for more than ten customers. Furthermore, the company aims to introduce Oasis Beta in 2028, a system with re-entry capabilities that will allow clients to retrieve physical samples from orbit for further analysis.
