Cowboy Space Corporation Raises $275 Million Series B for Orbital Infrastructure

Cowboy Space Corporation


, the orbital infrastructure company founded by Robinhood co-founder Baiju Bhatt, announced $275M in Series B financing at a $2B valuation led by

Index Ventures

, with participation from new investors IVP, Blossom Capital, and SAIC, alongside existing investors Breakthrough Energy Ventures, Construct Capital, Andreessen Horowitz, NEA, Interlagos and Baiju Bhatt. The company, which operated as Aetherflux since its founding in 2024, is also unveiling its new name and brand.

Cowboy Space Corporation

is pioneering vertically integrated infrastructure to power and run

AI

compute in orbit, opening a new frontier for high-performance computing as terrestrial capacity strains under AI demand. The company is developing a constellation of

Low Earth Orbit

satellites that harness solar energy, a purpose-built

launch vehicle

to deliver them and compute

payloads

designed specifically for the space environment. The rocket's upper stage and

data center

payload are designed as a single vehicle eliminating redundant mass and optimizing power and compute delivered to orbit. In orbit, each upper stage becomes a 1-megawatt data center.

Cowboy

is also collaborating with

NVIDIA

to deploy NVIDIA Space-1 Vera Rubin Modules, bringing state-of-the-art AI infrastructure to the Low Earth Orbit environment.

"Our approach starts from a blank sheet, where the unique requirements of



data centers



in orbit drive the form and function of the overall system,"

said Baiju Bhatt, founder and CEO of Cowboy Space Corporation.

"The rocket and the data center are a single design from day one. It’s a first-principles departure from the traditional constellation model."

"



Cowboy



is building at exactly the right moment, as demand for



AI



compute and energy begins to outstrip what terrestrial infrastructure can support,” said Jan Hammer, Partner at Index Ventures. “Baiju has a proven track record of reimagining massive markets from first principles, and his lifelong passion for physics makes space the ultimate market opportunity for that ambition. We're excited to back the team as they execute on this vision."

The company plans to launch its first satellite to orbit later this year to demonstrate space-to-Earth power beaming. Its team includes engineers from

SpaceX

,

Astranis

,

NASA

, Kuiper and

NVIDIA

.
