California Forever: The Startup Building America's Next Great City

October 21, 2025

Key Takeaways Copied to clipboard!

  • California Forever, led by Jan Sramek, is developing a new, self-funded, and sustainable city in Solano County, California, spanning over 100 square miles, to address the state's failure to build necessary infrastructure and housing. 
  • The project aims to revitalize California's innovation engine by co-locating advanced manufacturing (the Solano Foundry) and critical national security assets like West Coast shipbuilding facilities near Silicon Valley's AI/robotics talent. 
  • The proposed city will blend 21st-century industrial needs with traditional, walkable neighborhood design, aiming to create an affordable and desirable community for up to 400,000 people, serving as a 'new shining city on a hill' for America's current era of reindustrialization and abundance.

  • Key Takeaway: California Forever aims to build a livable, affordable, and eco-friendly community on over 100 square miles in Solano County, backed by Silicon Valley investors.
  • Summary: The project intends to recreate the high-tech manufacturing environment Northern California possessed in the 60s through 80s. The new city is planned to be entirely self-funded and sustainable. The core motivation is addressing the throttling of Northern California’s innovation engine due to a lack of housing.
California’s Irreplaceable Role

  • Key Takeaway: Despite its flaws, California is deemed irreplaceable in its current role within the United States, necessitating a fight to fix its systemic issues.
  • Summary: Jan Sramek contrasts the California dream he knew growing up in post-Soviet Eastern Europe with the reality he found in 2013, characterized by homelessness and corporate departures. He attributes these problems to a self-inflicted failure to build sufficient housing, office space, factories, and infrastructure. The speaker believes the defining question for America’s next 20 years is how to build again.
Project Scale and Location

(00:03:44)
  • Key Takeaway: California Forever has acquired nearly 70,000 acres (over 100 square miles) in Solano County, located between Silicon Valley and Sacramento, to facilitate large-scale building.
  • Summary: The land acquisition represents five times the size of Manhattan Island and two and a half times the size of San Francisco. This site is positioned at the Sacramento Bay and Sacramento River confluence, providing a canvas for necessary development.
Solano Foundry and Manufacturing

(00:04:44)
  • Key Takeaway: The first major component is the Solano Foundry, an advanced manufacturing park designed to allow Silicon Valley R&D to co-locate with production using robotics and AI to compete globally.
  • Summary: Competing with China in manufacturing requires increasing productivity per worker through automation, not just adding personnel. This proximity is crucial because the necessary robotics and AI talent predominantly resides in the Bay Area, making current long-distance travel to factories inefficient.
Shipbuilding and National Security

(00:06:13)
  • Key Takeaway: The project includes developing a major West Coast shipyard in Solano County to address the critical national security deficit in US shipbuilding capacity compared to China.
  • Summary: China’s Zhongjing Island shipyard built more ships last year than the entire US since WWII, and Chinese commercial ships are built to military standards. The Solano County waterfront offers the scale needed to host all current US shipyards combined, strategically located on the West Coast to bypass potential Panama Canal disruption.
City Design and Community

(00:08:42)
  • Key Takeaway: The city component will support the industrial base by housing up to 400,000 people in a walkable environment inspired by traditional American neighborhoods like Charleston and the West Village.
  • Summary: The architectural inspiration focuses on traditional, beautiful aesthetics where children can walk to school safely and public squares foster community. This design directly addresses the current inability of many Americans and Californians to afford or find such desirable living environments.
Symbolism of the Project

(00:09:24)
  • Key Takeaway: California Forever is positioned as the physical manifestation of America’s current need for building, abundance, and reindustrialization, mirroring historical achievements like the Hoover Dam or the Moon landing.
  • Summary: The project aligns with the growing ‘reindustrialized’ and ‘abundance’ movements calling for the US to meet the moment through large-scale construction. It aims to embody optimism, manufacturing revival, shipbuilding capability, and housing solutions.
