A New iPhone Is Coming. Should You Upgrade or Just Fix Your Old One?

One thing he hasn’t added: any other employees.

The 40-year-old is part of a class of entrepreneurs who are launching, and then often running, new companies on their own. Artificial intelligence tools answer Broca’s emails, help write and debug code, field requests from customers, sign up new subscribers and grant refunds when issues arise.

Broca relishes his ability to make whatever decisions he wants on his own, often from his sun-drenched Sausalito, Calif., living room. “I think compromises make lukewarm results,” he said.

Once upon a time, running a business of a certain size required a team. AI is turning that assumption upside down, and more aspiring entrepreneurs are going it alone.

An analysis by the payments company Stripe shows there are thousands of solo operators on the company’s platform that are generating over $1 million in revenue, with their ranks doubling between 2023 and 2025. The number of solo operators crossing the $10 million threshold nearly tripled in that same span.

In the past, people without business contacts or particular savvy might not have known how to get their ideas off the ground, said Ernie Tedeschi, Stripe’s chief economist. “Now, AI can be a built-in business partner,” he said.

AI’s ability to handle various administrative tasks makes it potentially useful for launching solo businesses in many fields. But the technology’s ability to also handle key tasks in tech, like coding, make that field a particular hot spot.

Analyzing Census Bureau data, Bank of America Institute economist Taylor Bowley found that among all industries, new business applications in the information sector have seen the biggest percentage increase—nearly 45%—over the past year. At the same time, the rate of information-sector applicants saying they plan to hire workers has experienced the sharpest decline of any measured industry.

This Census dataset doesn’t track solo-operated businesses. But the numbers broadly show—in tech and beyond—that applications are flat among businesses likely to hire workers, but generally rising elsewhere. Economists say that’s a strong sign that solo operators are on the upswing.

“The bar for getting started has never been lower,” said Julian Weisser, who runs a San Francisco-based accelerator for solo founders working in tech. The accelerator—which offers founders seed money and mentorship in exchange for an equity stake—attracted 4,500 applicants for 10 slots made available in its most recent cycle, nearly five times the number it drew when it launched last May.

Going it alone with AI can still be surprisingly expensive. Broca said he was losing money on many customers’ accounts while paying to access Anthropic’s Claude to run his clients’ requests—that AI company, as well as others, charges based on usage. He has since switched to free open-source AI models from China.

Broca said he has raised $30 million from investors and, at the same time, has saved millions in salary since he hasn’t needed a team of software engineers.

Another risk: If it’s easy for one entrepreneur to launch an AI-assisted business, copying them can be easy, too. This creates anxiety for founders like Troy Johnston, who runs an AI-assisted business alone in Orlando, Fla.

“Everybody has the sword and we all have the ability to unsheathe Excalibur now,” said Johnston, 40, who used AI to code an app that helps people get the most out of credit card benefits. The company makes around $3,000 a month in profit, with no employees, and is continuing to grow.

What one-person businesses will mean for the labor market remains to be seen. Polling has shown Americans are worried that AI will replace jobs, and top economists are wrestling with that possibility, too. But AI is also creating lots of new jobs, and the go-it-alone entrepreneurs show how the technology can both open doors and limit employment opportunities.

“If everyone’s hiring less, but you get four times more firms, what does that do to head count?” said Rembrand Koning, an associate professor at Harvard Business School who studies entrepreneurship. He co-authored a recent study that found that among 50,000 startups the researchers examined, those focused on AI tended to operate with 25% fewer employees.

Koning also believes a soft hiring environment that’s left some people mired in long job searches has encouraged more to try their hand at launching businesses.

Some founders cite different motives. “It’s a perfect storm of post-pandemic burnout and a re-evaluation of one’s priorities, and also booming AI and a sense of what’s possible,” said Samir Ahmad, 39, who lives in Breinigsville, Pa.

Two years ago, Ahmad decided to leave the corporate job he had worked at Verizon for almost two decades to start a solo coaching and consulting business. He had been seeing social-media posts touting the ease and virtues of AI, which he used to chart a business plan and help with marketing. “It was like my chief of staff, a second in command,” he said.

The business ultimately petered out within months, though, and Ahmad is now back to a full-time corporate role with a utility company.

For Claire Vo, 41, AI helped her turn a passing impulse into a business. She was working full-time as a tech executive when she tapped AI in late 2023 to help code an app that would help her manage documentation and design for new products, with customers ranging from financial services to healthcare firms.

“I was copying and pasting from ChatGPT,” said Vo, who lives in San Francisco.

She put the app online for $1 a month, and within weeks people downloaded it thousands of times. Nearly three years later, Vo’s company—which she ran solo for nine months before hiring an engineer—now has 100,000 users and is on track to make seven figures in profit this year. AI handles the company’s marketing, sales and customer support.

While AI is a shortcut, Vo said her network and credibility in the industry were key. “I think people over-index on how easy AI is and under-index on how much I did to get to this point,” she said.
