About Endurance
from Seattle, WA
Spirit of Endurance
Endurance is named after Shackleton's Antarctic expedition because it captures something fundamental about the people we want to build with. The moments that define history are rarely the ones that go according to plan. They're the moments when exceptional people confront the unknown, think from first principles, trust one another, and find a way forward together.
We're building Endurance for the people who view the unknown as an invitation. Every day at Endurance is an opportunity to build something that has never existed before, alongside people who wouldn't choose to be anywhere else.
The expeditionary spirit reaches into every corner of Endurance. Krill, Adelie, Silverfish, and Orca are all named after species in the Antarctic food chain, a small tribute to the journey that inspired our company.
How We Build
Our mission
Deliver clean, affordable baseload power through subsea geothermal. We're building the world's first commercial subsea geothermal platform.
Values
The hardest problems are usually the most important ones. We think from first principles, build hardware, test relentlessly, and let reality decide. Every deployment teaches us something. Every iteration makes the system stronger.
The Expedition
Meet The Team
Every deployment has a story. Every engineer has a different path here. Meet the people building Endurance, hear what they've learned, and discover why they chose the expedition.

Operating Principles
Mission Experience
Endurance brings together leaders who have built some of the world's most ambitious technology companies and helped shape the future of American energy.
Our team includes veterans of SpaceX, Helion, and Robinhood, alongside leaders with experience in U.S. energy policy and national strategy. Together, they unite expertise across engineering, manufacturing, markets, and public policy to accelerate the future of abundant energy.
Headquarters
Endurance is headquartered on the north shore of Lake Union in Seattle, Washington.
From our waterfront facility, subsea drills and generators move directly from the workshop onto the vessels that carry them into the Pacific. It's not unusual to see a prototype leave the shop in the morning and be headed for open water by the afternoon.
