Tumbleweed Raises €6.9Mn in Austria’s Largest-Ever Spacetech Seed Funding Round

The funding comes just four months after the company launched Austria’s first commercial satellite.

The round was led by PactVC, with participation from Vanagon Ventures, early investor Prototype Capital, EWOR, and several international investors and angel investors.

“We're moving from universities and hospitals towards national research institutes, contract research organisations and eventually much broader industrial adoption,” Rothenbuchner said.

“Our philosophy is to integrate microgravity into existing supply chains. For microgravity to become a major commercial market, it needs to become as unremarkable as the internet is today."

Daniel Dippold, CEO of EWOR, commented: “Julian has done exactly what he told us he would do when we first met him, only faster. Now every lab and manufacturer can use space without becoming a space company first.”

Andreas Klinger, founder of Prototype Capital, added: “Tumbleweed completely rethinks how R&D for industry and science in space should be done. This allows rapid iteration for the next generation of space technologies. It's hard to overestimate how important this can become.”

Founded in 2024, Tumbleweed operates in Vienna and Delft. The company is developing modular laboratory Pods that will be hosted aboard its free-flying Oasis platform in space.

Its technology allows researchers, manufacturers and research teams to carry out experiments in microgravity without having to build or manage their own space infrastructure.
