Tumbleweed Funding Round

11/3/2026

Venture Equity

$7,500,000

Seed

The fresh capital will be used to fund and accelerate three upcoming orbital missions planned for 2027, scale its customer base across biotech and advanced manufacturing, and drive the development of Oasis Beta--Tumbleweed's next-generation orbital platform scheduled for 2028 that will feature re-entry capabilities to safely return physical experimental samples back to Earth.

We make microgravity accessible for research and industry. Tumbleweed was born out of a simple frustration: space is full of potential, yet almost impossible to use. We've been building space systems for years, including early work on wind-driven Mars rovers through Tumbleweed Mars. These projects shaped our engineering approach and highlighted a broader challenge: access to space is not limited by ideas, but by execution. As our expertise grew, we saw a critical need closer to home. Researchers and manufacturers are eager to leverage the benefits of microgravity, but the journey to orbit remains slow, bureaucratic, and prohibitively expensive. We experienced first-hand that access to microgravity isn't limited by imagination and potential -- it's limited by logistics.
