Have you ever imagined data centers floating above us in the vastness of space? This futuristic idea is not as far-fetched as it sounds, as evidenced by Starcloud’s groundbreaking venture detailed in Y Combinator’s latest episode titled “Inside The Startup Launching AI Data Centers Into Space,” published on November 13, 2025. Starcloud, a pioneer in space-based technology, recently launched a satellite equipped with the NVIDIA H100 GPU—an unprecedented move that promises to revolutionize how we think about computing infrastructure. Their ultimate goal is to create massive orbital data centers that capitalize on continuous solar energy and the unique cooling properties of space to outperform Earth’s largest data centers with a fraction of the environmental impact.

Philip Johnston, along with co-founders Ezra Feilden and Adi Oltean, set up the startup less than two years ago, with a vision that might seem audacious at first—establishing highly efficient computing systems that bypass terrestrial constraints such as land, water, and grid limitations. Unlike their Earth-bound counterparts, Starcloud’s data centers promise zero freshwater use and significantly reduced carbon emissions by discharging heat into space.

The concept is visionary—enlisting the natural heat dissipation properties of the cosmos rather than engaging in costly cooling processes on Earth. Yet, as admirable as this effort is, it is not without its skeptics. Critics have voiced concerns over the feasibility of maintaining large surface areas necessary for heat dissipation in space. Fortunately, Ezra Feilden’s extensive experience designing deployable structures in space addresses this challenge, creating expansive radiators that serve as the company’s core intellectual property.

Starcloud’s founders have shown immense ambition not only in their vision but also in their rapid progress, achieving in 15 months what might take others longer. This speedy development was facilitated by a team with a complementary blend of skills, comprising experience from NASA and Microsoft, highlighting the powerful synergy of their expertise.

Though still in its infancy, Starcloud’s journey has already started capturing the imagination of major tech leaders. Companies like Google, SpaceX, and Amazon are reportedly curious about the concept of space-borne data centers. There’s certainly a magnetic pull towards the idea of setting up infrastructure high above Earth’s surface, unlocking possibilities far beyond the conventional.

With the successful deployment of their first satellite and a second, more robust one lined up for launch in 2026, Starcloud has taken a significant leap toward transforming the AI computing landscape. However, they must navigate technological and market risks carefully. Despite the hurdles, Philip Johnston believes that the effort is justified, given the game’s transformative potential—”anything worth doing is going to be hard.”

The implementation of data centers in orbit might still be years away from dominating the industry, but Starcloud’s initial endeavors represent an exciting step toward reshaping not just where, but how, we manage computational demands. It’s a thrilling prospect, albeit one that requires more evidence to ensure sustainable viability. As they venture into this unexplored realm, Starcloud’s progress presents a promising glimpse of a future where the sky is no longer the limit but the beginning of endless possibilities.
