The concept of a viable, fully functioning one-person business is no longer far-fetched. Sam Altman, co-founder of OpenAI, recently suggested that a single individual could realistically operate a billion-dollar enterprise by 2026–2028, leveraging GPT-5 and other generative AI tools to create and manage automated agents.
What once seemed inconceivable—one individual generating such scale of capital without staff or large-scale infrastructure—is now within reach. With advanced AI and low-barrier coding tools, the solopreneur model is emerging as a genuine business possibility.
The traditional start-up model
Since the 1970s, technology and software enterprises have generally followed a standardised approach:
- Develop an idea for a product.
- Prepare a business plan.
- Seek funding through private or public channels.
- Employ a team and establish operations.
- Build and release the product.
- Market to and convert customers.
- Refine the product and scale gradually.
- Aim to generate sustainable revenues and eventual profit.
This structure works but is resource-intensive, requires multiple personnel and significant capital investment, and is slower to scale.
The one-person business model
By contrast, the one-person model relies on AI to remove staffing requirements and automate core processes. Typically, a solopreneur would:
- Start by identifying and engaging with an audience, often through social platforms.
- Analyse customer needs to shape the business proposition.
- Use AI to rapidly develop a coded prototype.
- Launch, refine and scale based on real-time feedback.
- Build a customer community around the product.
- Deploy AI agents to automate service delivery.
- Expand reach and revenues quickly, targeting higher profit margins.
This model is leaner, faster, and potentially managed entirely by one individual with the ability to apply AI effectively.
The opportunity
The key opportunity lies in eliminating the traditional constraints of a start-up. Specifically:
- Staffing costs are negligible, with AI replacing many human roles.
- Service delivery is fully digital, avoiding physical production expenses.
- Overheads remain minimal, improving margins.
- AI agents can scale alongside demand.
- Automation reduces the owner’s need to work in the day-to-day operations.
- The solopreneur retains both income and lifestyle flexibility.
The risks
As with any emerging model, risks remain:
- Excessive automation may reduce customer engagement.
- Technical failures could disrupt operations and limit growth.
- AI outputs may lack quality control.
- Operating without partners can create pressure and isolation.
- The absence of a human team may reduce collaboration and innovation.
Altman’s forecast of a billion-dollar, one-person enterprise could well be realised in the next few years. With the rapid pace of AI development, the barriers are lowering, and the potential is considerable. However, achieving long-term sustainability will depend on balancing automation with human oversight and ensuring that efficiency does not come at the cost of customer value.
