Skyler Chan
Founder and CEO of GRU Space, officially Galactic Resource Utilization Space, a YC Winter 2026 startup developing lunar-regolith brickmaking, inflatable habitats, and planned permanent lunar infrastructure starting with a Moon hotel.
GRU Space Plans Lunar-Regolith Bricks as the First Step Toward a Moon Hotel
On This Week in Startups, GRU Space founder Skyler Chan argues that a Moon hotel is the first commercial wedge for a larger off-Earth manufacturing business: using lunar regolith to make construction materials rather than shipping them from Earth. Chan lays out a plan to prove the technology by making a brick on the Moon, then scale toward robotic habitats, NASA construction work, space tourism and eventual claims on lunar resources. The same episode turns to Anthropic’s forced shutdown of Fable 5 and Mythos 5, which Jason Calacanis and Lon Harris frame as a warning that frontier capabilities can be cut off before law, politics and operating norms have settled.
GRU Space’s Moon Hotel Depends on Turning Lunar Dirt Into Infrastructure
Skyler Chan of GRU Space argues that the company’s proposed lunar hotel is less a tourism stunt than a test case for building infrastructure from the moon itself. In an interview with Jason Calacanis and Lon Harris, Chan said GRU’s core bet is that concentrated sunlight can melt lunar regolith into durable building material, reducing the need to haul construction supplies from Earth; the episode also used a contested rumor about Anthropic to examine how closely frontier AI labs are becoming tied to U.S. national-security institutions.
