What happens when billionaires grow tired of tweaking the systems that exist? They build their own.
From self-sustaining cities in deserts to high-tech communities floating in international waters, a growing number of billionaires are pouring money, tech, and ideology into building private cities. These aren’t just luxury retreats. They’re complex experiments in governance, sustainability, and urban design.
For entrepreneurs, this is more than just a curiosity, it’s a signal. A signal that the next frontier for innovation might not be just software or fintech, but entire ecosystems built from zero.
Let’s explore the billionaires who are building their own cities and what Indian founders, policymakers, and innovators can learn from this rising global trend.
Elon Musk is the perfect example of thinking beyond boundaries. His city project, Starbase, is already operational in Texas. It’s part of SpaceX’s testing and development ground, but Musk wants it to be much more: a launchpad for humanity’s future on Mars.
For startup founders in India, Musk’s Mars vision might feel far-fetched, but there’s a practical insight here—founders need to build ecosystems, not just products. Whether it's through hubs, accelerators, or digital communities, creating an enabling environment is key to scaling something disruptive.
And Musk’s approach proves that if the environment doesn’t exist, you build your own.
Former Walmart exec and entrepreneur Marc Lore is applying a startup mindset to city-building. His city-in-planning, Telosa, aims to mix economic efficiency with social equity. His pitch is simple: what if a city ran like a well-funded startup, but served the public like a mission-driven non-profit?
Telosa is rooted in something Lore calls “equitism,” where land is owned by a public trust and value is redistributed. Green tech, clean mobility, and open data are at the heart of this urban experiment.
For founders, especially in sectors like cleantech and urban innovation, Telosa is a model worth watching. It’s a testbed where new technologies will be trialed at scale, and that means potential opportunities for smart city startups.
Peter Thiel, co-founder of PayPal, took the contrarian route by funding seasteading projects, floating cities that operate outside national jurisdictions.
It’s a libertarian dream of self-governance, free enterprise, and autonomy. While the project has mostly stalled, it introduced an idea that’s becoming more mainstream: what if we can build entirely new systems of living and working?
Indian startup founders working in decentralised tech, blockchain, and governance tools could find inspiration here. If DAOs are digital cities, seasteads are their physical counterparts.
The Line, part of Saudi Arabia’s $1 trillion NEOM project, is one of the most technologically ambitious urban developments on the planet. It’s a 170-kilometre linear city with zero cars, zero emissions, and complete reliance on automation and AI.
Imagine a place where everything is walkable, energy is 100% renewable, and logistics are handled by underground transit.
While political concerns and feasibility debates continue, for Indian urbantech and AI startups, The Line represents a bold experiment—and possibly a new kind of market. Entrepreneurs working in IoT, sustainable infrastructure, and city-as-a-service models will find plenty of insight (and maybe investment) in projects like NEOM.
Microsoft co-founder Bill Gates invested $80 million into Belmont, a smart city in Arizona designed for autonomous vehicles, data-driven planning, and clean energy systems.
Unlike some of the more idealistic projects, Belmont’s strength lies in its incremental innovation. It doesn’t aim to upend governance, it aims to improve it.
For Indian founders, this kind of city presents potential collaboration opportunities. From civic tech to mobility-as-a-service, Belmont (and similar smart cities in India) could become platforms to scale innovations that directly impact urban lives.
Oracle co-founder Larry Ellison bought 98% of Lanai, a Hawaiian island, and turned it into a controlled experiment in eco-tourism, renewable energy, and wellness.
While less accessible to the public, Lanai offers lessons in closed-loop systems, resilience, and tourism tech. It’s also a model for founders working at the intersection of climate, agri-tech, and hospitality.
In India, similar visions are emerging in places like Rishikesh, Coorg, and Auroville, where tech-enabled eco-communities are taking root.
Retail billionaire Les Wexner shaped New Albany, Ohio into an ultra-curated suburban town, complete with upscale architecture and carefully planned zoning.
Think of it as a D2C city, built with the same philosophy Wexner applied to fashion brands. The lesson? City building is branding, and branding is increasingly part of place-making.
For Indian D2C founders and real estate-tech players, New Albany is a reminder that consumer psychology extends beyond the internet, into homes, schools, and public spaces.
Unlike the others, Mark Cuban bought the town of Mustang, Texas, not to build an empire, but to help a friend battling cancer. He has no major plans for the land.
It’s a different kind of power, a reminder that impact doesn’t always need scale or spectacle.
India is slowly entering this space, with its own billionaire-led city-building efforts:
Mukesh Ambani’s Jamnagar, already a petrochemical hub, is now evolving into a sustainable, smart industrial city.
The Adani Group is investing in tech-driven townships and green urban zones, aligned with India’s broader Smart Cities Mission.
Cities like Gift City in Gujarat are testing digital infrastructure, fintech regulation sandboxes, and decentralised utilities.
But as Indian billionaires start shaping urban futures, the country also faces critical questions:
Will these new cities include the middle class and working poor?
Can entrepreneurs access these ecosystems for innovation?
Will these cities be truly collaborative or heavily top-down?
These billionaire-built cities are more than vanity projects. They’re labs for future urban systems, and India’s startup ecosystem can’t afford to ignore them.
Opportunities lie in:
SaaS platforms for urban management
Mobility and logistics solutions for new layouts
Sustainability tech for water, energy, and waste systems
AI and automation for public services
Real estate innovation from fractional ownership to digital twins
But the challenge is clear: these projects cannot just serve billionaires or tourists. The real winners will be cities that welcome entrepreneurs, startups, and everyday citizens.

Billionaire-backed cities might feel like science fiction, but they are quickly becoming very real. Whether it’s on a Hawaiian island, a Texas launchpad, or an Indian smart township, these experiments are writing the first chapters of a new urban era.
As a startup founder, investor, or policy thinker, you need to stay ahead of the curve. These cities will need tech, infrastructure, governance models, and communities. And that means they will need you.
The only question is, will you help build them, or will you watch from the outside?
