Thanks @YCombinator for documenting @Starcloud_Inc1’s journey to launching the first @Nvidia H100 in space 🙏 Check it out below! 🎥🤓
Y Combinator@ycombinator

Starcloud (@Starcloud_Inc1) recently made history by launching a satellite with an NVIDIA H100 into orbit — the first time a GPU that powerful has ever operated in space. It's the first step toward building AI data centers in orbit, powered by continuous sunlight and cooled by radiating heat into deep space. Their approach could one day rival the world's biggest data centers while using less energy, zero fresh water, and far lower emissions. YC's @aaron_epstein visited Starcloud's HQ, where co-founders @philipjohnston, @EzraFeilden, and @Adi_Oltean explained how they built a working prototype in just 15 months — and why big tech is racing to space for AI compute.

@PhilipJohnston @Starcloud_ Bravo 🙌 @Starcloud_ courage and your perseverance, your visionary and philanthropic efforts to create pathway to sustainable energy. I’m sure that in the beginning many people even friends might have said that it was not going to help or work out. x.com/Starcloud_/sta…

The 2024 @Starcloud_ white paper will be viewed historically as a significant turning point 🤓 Correction though, while we were a serious team of three, there wasn’t serious money or serious people paying attention in mid 2024. @bailey55015/starcloud-starcloud-084fad279913" target="_blank" rel="nofollow noopener">medium.com/@bailey55015/s…

Thanks Gali!! 🙏🙏

I like Starcloud because they put the first datacenter in space and it works. Based in my hometown (Seattle area) I met the CEO and he has that dawg in him and put together an amazing team growing at lightning speed. Very high risk and high reward, but if AI keeps its trajectory compute demand will be insane. Datacenters in space will be one of the largest pieces of the global economy. Easily trillions, then tens of trillions. If Starcloud stays a leader this could become one of the world's largest businesses + whatever other schemes they develop (asteroid mining? bitcoin space mining? living in space? who knows!?)

How is the @Gmail spam filter so terrible?? Just have @GeminiApp scan it, it really cant be that hard. And if it costs more charge us more, im happy to pay @GoogleDeepMind!

There's a huge risk to orbital datacenters which I'm surprised I haven't seen discussed anywhere. All SSO datacenter operators need to align their orbital direction: strictly prograde (dusk-dawn) or strictly retrograde (dawn-dusk). If even a small number of players decide differently from the rest then head-on collisions are essentially guaranteed. A single collision would release 40 tons of TNT, quickly turning this very special orbit into a debris field. The good news is - the solution is very simple. There are few benefits of mixing dawn-dusk with dusk-dawn. Everyone just needs to choose dawn-dusk. Starcloud is working hard to make this happen. DM me if you are a dawn-dusk SSO user and would like to help.

Say what you will about orbital data centers but you have to give some credit to @PhilipJohnston here. It’s so easy as a hyped tech founder to dodge the hard questions and just ride the wave. The Starcloud team is calling their shot and openly talking about the risks. Not faking milestones and doing pure PR nonsense. Regardless of the outcome, I respect the intellectual honesty.

Starcloud CEO @PhilipJohnston joins @itsmoislam and I at the NYSE. "In order to make data centers in space work, you really need the BOM costs for a 200 kW satellite to be on the order of 1 million dollars." We chat: - Building low cost sats - 20 yr terrestrial vs. 5 yr space - Merge with a launch company? - Does Starcloud exist if Earth's bottlenecks vanish? - Better leader: Altman or Dario - Building sats cheaper than Starlink - GPU failure rate

u wudn't necessarily need the spaceX bus, all u have to do is build in a "flattelite" flat-pack form factor suited for 'pez dispensing' from starship into the void .... @VladSaigau @Yrouel86 → *88,000 Satellites?! Starcloud CEO Interview (Philip Johnston)🛰️* HyperChange Mar 4, 2026 youtu.be/Xyvaev2CZV4?t=… I sat down with Philip Johnston, the Founder of Starcloud at the company's Redmond HQ: → 00:06:17 @PhilipJohnston Mar 4 --> "So, in the short to medium term the next decade, we're launching many many inference nodes. So, we're expecting them to be about 200 kW, about 3 tons. It's what you can launch on the Starship PEZ dispenser form factor. So, you know, they have those discs that slide out the side. And what's nice about it is you can launch you know, up to 50 per Starship launch. So, we're talking about then 10 MW per Starship launch. If you're launching once Starship is flying at a rate and they're flying hundreds, you know, we can potentially be flying hundreds per month. We're talking about tens of gigawatts of new capacity of compute per year just in this inference constellation. So, that's what we're going for." → [recent starcloud update] This Week in AI - "Things that would take a PhD researcher a day, like what percentage of the time in a sun-synchronous orbit of this altitude are you going to be in the sun? AI can do in 15 minutes." @PhilipJohnston on Starcloud's AI-led productivity gains. @Jason @Starcloud_ TWiAI Episode 13 out now: youtu.be/QEu9_0R4eAU&t=… Image 9:45 AM · May 13, 2026·4,116 Views x.com/ThisWeeknAI/st…
