Tumbleweed Raises €6.9M for Microgravity Research
Austrian startup Tumbleweed has raised €6.9 million in the country's largest-ever spacetech seed round. PactVC led the round, with participation from Vanagon Ventures, Prototype Capital, EWOR, and international angels. Founded in 2024, Tumbleweed develops modular laboratory Pods hosted on its free-flying Oasis orbital platform, making microgravity accessible to researchers, manufacturers, and R&D teams. Its first mission, Oasis Alpha, launched on SpaceX Transporter-17 in July 2026, carried experiments for four customers, and was fully booked a year before launch. The company offers services from €15,000, with lead times of two to three months. Tumbleweed plans three missions in 2027, carrying more than ten customers, and aims to expand from universities and hospitals to national research institutes and industrial adoption. The company is developing its own reentry vehicle for Oasis Beta in 2028 to return physical samples to Earth.
This is a notable funding event in the emerging spacetech sector, but it is not directly relevant to the AdTech/MarTech industry. It may have implications for space-based data and research, but lacks direct advertising or marketing technology relevance.

SpaceX Launches Starfall Microgravity Capsule Service
SpaceX has introduced Starfall, a disc-shaped capsule designed to carry up to 1,000 kilograms of cargo into orbit and return it to Earth after weeks of microgravity. The service, marketed as an affordable and routine access to weightlessness, targets biomedical research, pharmaceutical crystallization, and materials science. Starfall will be launched aboard Starship, offering a reliable and scalable flight cadence. SpaceX has already signed three commercial missions, with flights planned for 2028, including customers Space Cargo Unlimited and Redwire. The announcement comes the same week as Vienna-based startup Tumbleweed raised €6.9 million for its own return capsule. SpaceX's entry intensifies competition among microgravity service providers, including Varda Space Industries, which has completed six return missions, and several European startups.
The Exploration Company Raises €387M for Reusable Rocket Engine
The European Space Agency (ESA) has awarded its largest-ever contract to a European space startup, The Exploration Company (TEC), for cargo transport to the International Space Station (ISS). The service agreement, signed at the International Space Summit in Paris, is worth up to €760 million, including €310 million for a demonstration mission and €450 million for two optional missions. TEC must raise 40% of the demonstration cost privately. This follows TEC's record $450 million Series C round (€387 million), bringing total funding to about $680 million. The contract is part of ESA's ALADDIN program, formerly LCRS, signaling a strategic shift toward commercial space services. TEC's reusable Nyx capsule, targeted for ISS docking by November 2028, will be launched on an Ariane 6 rocket by Arianespace. TEC also has agreements with commercial space station operators Axiom, Starlab, and Vast. Founded in 2021 by CEO Hélène Huby, TEC employs over 550 people and has over $2 billion in contracts and commitments.
Stellar Alpina secures €160K from Venture Kick
Zurich-based space startup Stellar Alpina has raised €160,000 (CHF 150,000) from Venture Kick to develop compact rotating detonation rocket engines (RDREs) for in-space propulsion. The funding will support expanded testing infrastructure, further hotfire campaigns, and development of a first flight engine. Founded by Rick Röthlisberger, Simi Y. Wespi, Victor Elliesen, and Patrick Egli, the team emerged from ARIS, a Swiss academic spaceflight initiative. RDREs use continuously rotating supersonic combustion waves to generate thrust, offering potentially smaller, lighter, and more efficient propulsion for satellite maneuvers, orbital transfers, and future deep-space missions, addressing the growing need for in-space mobility as launch frequency increases.
