The One Person Startup: Building with AI
What if you could build a business without hiring a large team, raising capital or spending months developing a product before launching it?
Traditionally, starting a company required developers, designers, marketers and support staff. Even a simple software idea could take significant time and money to bring to market.
AI is changing this. Founders can use AI tools to write code, create designs, research markets, produce marketing content and automate routine tasks. Work that once required several employees can now be managed by a much smaller team.
This gives entrepreneurs more room to experiment. They can develop an initial product, test demand and improve it before committing significant resources. But having access to AI is only part of the equation. Building a sustainable business still requires customers who are willing to pay.
These three solo entrepreneurs show how AI can support founders and small teams in building and growing a company.
Matthew Gallagher: Scaling Medvi
Matthew Gallagher founded Medvi, a telehealth company that connects customers with online healthcare services. The business has reported $401 million in sales during its first full year and is projected to reach $1.8 billion in 2026.
Medvi has attracted attention for its lean operating model, using AI tools and contractors to handle work that might otherwise require a much larger internal team.
Its growth shows how technology and outsourced expertise can help a business manage operations and expand without building a traditional corporate structure from the outset.
Medvi operates in healthcare, however, where regulatory compliance, patient safety and appropriate clinical oversight remain essential. Its model is not simply about replacing people with AI, but using technology and external expertise to support growth. medvi.org
Danny Postma: Turning AI Headshots Into a Business
Danny Postma created HeadshotPro, an AI tool that turns ordinary selfies into professional looking headshots. It offers job seekers, freelancers and businesses an alternative to traditional professional photography.
Rather than building an entirely new AI model, Postma applied existing technology to a specific customer need. Users upload their photos and receive AI-generated headshots without booking a photographer or arranging a photo shoot.
Postma built the business while working independently from Bali, demonstrating how a founder can operate an online business without a traditional office or large team. HeadshotPro has reportedly reached around $300,000 in monthly revenue. HeadshotPro
David Holz: Building Midjourney
David Holz founded Midjourney, an AI image-generation platform that creates images from text prompts. It enables artists, designers and other users to explore visual ideas and produce images using AI.
Midjourney demonstrates how a small team can build a technology business at significant scale. The company has generated substantial revenue with a relatively small workforce compared with many traditional technology companies.
Its subscription model provides recurring revenue, while its focus on image generation gives users a clear reason to return. Midjourney
What Makes a Solo Startup Successful?
These examples highlight three principles for founders who want to build efficiently.
Solve a problem people will pay to fix. HeadshotPro makes professional headshots more accessible, Medvi provides online healthcare services, and Midjourney enables AI image generation. Each business offers a clear service rather than trying to appeal to everyone.
Use resources strategically. AI, automation and contractors can reduce the need for a large permanent team. Founders can focus their time and money on the tasks that require their attention, while using technology for suitable repetitive work.
Choose a sustainable revenue model. A product needs a reliable way to generate income. Whether through service purchases, telehealth offerings or subscriptions, businesses must give customers enough value to justify the price.
The Limits of Going Solo
Running a business independently does not mean every task can or should be automated. Products need maintenance, customers need support, and security, reliability and cash flow require attention. AI-generated work can also contain errors, making human judgement essential.
Some industries require specialist expertise and oversight. Healthcare businesses such as Medvi must account for clinical responsibilities and regulatory requirements, while AI platforms such as Midjourney need technical expertise to maintain their systems.
As a business grows, its founder may need to bring in specialists to maintain quality, support customers or develop new capabilities. The goal is not necessarily to remain a team of one, but to build efficiently and add people when their expertise creates value.
The Future of the One-Person Startup
Danny Postma's HeadshotPro demonstrates how a founder can turn existing AI technology into a focused product. Matthew Gallagher's Medvi illustrates how a lean operating model can support rapid business growth. David Holz's Midjourney shows what a small team can achieve by building a specialised AI product at scale.
Their businesses are different, but they share an important principle: technology creates value when it provides a solution to customers' needs.
