Small business takeaway:

  • Teen founders are using AI to build serious startups faster and cheaper, drawing backing from major venture firms and accelerators. The lessons extend beyond youth entrepreneurship: AI can compress the distance between idea and real market demand; knowing how to turn new tools into practical business advantages is becoming a competitive edge; and even promising founders need experienced guides to turn early momentum into lasting companies.

Young teens empowered with artificial intelligence technology are launching innovative startups that are catching the attention of investors worldwide. 

It’s a trend that has picked up momentum over the past two years as advancements in AI platforms like ChatGPT, Claude, and code assistants help these entrepreneurs dramatically reduce startup costs by eliminating the need for expensive software and tech hires for upfront product development and prototyping. It has allowed them to build apps, code software, build websites, and generate marketing materials at warp speed all on their own. 

While young entrepreneurs are not anything new, the age of this new crop of founders has dropped significantly with some founders as young as 15.

Venture capitalists are recognizing the shift, and some prestigious firms, including Andreessen Horowitz, General Catalyst, and Kleiner Perkins, are funding teen upstarts. They want to capitalize on their digital know-how in coding and artificial intelligence and their fresh perspectives on how to use technology to solve problems in areas ranging from healthcare to telecommunications. 

Accelerators and incubators are also tailoring programs to help teen founders incubate their product ideas. These include Young Founders Lab and Y Combinator

So are academic institutions like Georgetown University and Hofstra University, which are now offering virtual startup bootcamps or in-person courses for students ages 13 to 18 to build businesses, write formal business plans, and pitch to real investors. Some organizations, like Emergent Ventures, part of the Mercatus Center at George Mason University, offer grant programs to U.S. teens and international students as well.

“Teen founders operate at the frontier, and AI has stripped away the barriers —like managing large teams—that used to hold them back,” said Shruti Rajagopalan, a Senior Research Fellow at the George Mason University’s Mercatus Center who leads Emergent Ventures India, a grant and fellowship program for high school and college students and scholars who are launching startups. “They experiment with new tools, technical possibilities, and company ideas before the broader market understands them.”

As she explained, these teenage founders are digital natives who are astute at coding and social media. They have an advantage over many older peers when building apps, platforms, and other tech products, according to Rajagopalan.

Walter Kortschak, Founder and Managing Partner of Firestreak Ventures, a pre-seed stage venture capital firm, agrees that a growing number of teen founders are at the forefront of innovation. An early investor in Anthropic, he also invested early in Aaru, a $1 billion startup founded in 2024 by three teenagers that uses generative AI to simulate human behavior for market research, predictive intelligence, and policy analysis. Today, Aaru’s clients include top consulting firms including Accenture and Ernst & Young.

Most recently, Kortschak invested in Synthetic Sciences, a San Francisco–based startup founded by teen entrepreneurs that has created an AI platform for scientific research.

“Teen founders have AI-native intuition and are often driven by pure, unadulterated product focus,” he said. “We provide the institutional scaffolding and mentorship in addition to the capital to help them turn a brilliant project into a generational enterprise.” Recognizing this trend, VCs are increasingly interested in funding their ventures, he added.

Self-taught techies

The breakthroughs some of these teens are working on promise to disrupt key market sectors if their startups are successful. 

That is exactly what Siddarth Nandyala, a 15-year-old freshman at the University of Texas at Dallas studying computer science, is hoping for. Two years ago, the teen found Circadian AI, a smartphone app that uses artificial intelligence and machine learning to detect early signs of heart disease in 7 seconds by holding the phone close to the patient’s chest, where it records the heartbeat and uses cloud-based machine learning to analyze the sounds. The technology works with up to 96% accuracy, Nandyala claims.

The goal is to have the app used as a pre-screening tool by nurses and healthcare practitioners to identify high-risk patients with heart murmurs, arrhythmia, and other conditions. Considering cardiovascular disease is the leading cause of death worldwide, according to the World Health Organization, the technology aims at tackling a major health issue. 

Nandyala's interest in technology began at age 7, when he used LEGO software on an iPad to program a rover. "That was the spark that made me realize I could turn my ideas into reality and build things," he said.

After that he started teaching himself about coding and machine learning through tutorials on YouTube.

By age 12, he had earned an Arduino certification—a credential in electronics and programming.

Equipped with that knowledge, he launched his first startup in seventh grade called STEM IT, online courses to help young students learn about coding and technology.

Two years later, Nandyala launched Circadian AI to tackle heart disease screening. With hundreds of thousands of dollars earned from STEM IT, he began bootstrapping the startup to develop the app, conduct clinical and pilot trials, and develop a platform. Working with the government of India and its Department of Education, he developed a protocol to test the app through clinical trials at hospitals in the country. He also tested the app on about 15,000 patients at hospitals and medical institutions across the United States. The trials showed the app was accurate in diagnosing patients at risk, he said.

Now, Nandyala is looking to raise a $5 million Series A seed financing from venture capitalists. The money will be used to get FDA approval for the device. 

“Many healthcare companies, large tech companies, and hospitals have approached us to license our technology,” said Nandyala, who is optimistic about his company’s future. He notes the global market for cardiac devices is expected to grow to over $32 billion worldwide by 2034, according to Precedence Research.

Cashing in on innovation: Teen founders sell calorie-counting app to MyFitnessPal

Other teen entrepreneurs have created AI apps with remarkable success. Among them are Zach Yadegari and Henry Langmack, Co-founders of Cal AI, an AI calorie-counting app that, less than two years after its founding, reached 15 million downloads and generated more than $30 million in annual revenue. The app uses AI to automatically log in your meals. Instead of manually weighing or guessing food amounts, users simply take a photo of their meal, and the app calculates the calorie and nutrient breakdown. It also does goal tracking by monitoring daily activity and syncing it with personalized calorie goals.

The teens founded the company while in high school and got funding to develop its technology from angel investor and serial entrepreneur Blake Anderson. Then they bootstrapped the company’s growth. Last year, the founders sold the company to MyFitnessPal for an undisclosed amount. Yadegari and a small team of contractors have been retained by MyFitnessPal.

Teen-founded startup delegates complex scientific research tasks to AI co-scientists—and lands funding from big name investors

Another AI startup founded by 18-year-olds that’s getting a lot of attention from investors is Synthetic Sciences based in San Francisco. Last year, Aayam Bansal and Ishaan Gangwani, two high school students, co-founded the company that has created a platform where scientists can delegate complex research tasks to agentic AI co-scientists. The platform handles all research workflows—from hypothesis and experimentation to drafting research reports.

The two teens met while doing machine learning research at the National University of Singapore and then dropped out of school to independently work on their project. Gangwani received a $26,000 grant and fellowship from Emergent Ventures India to support advanced work on the platform and moved the startup to San Francisco.

After getting into the prestigious Y Combinator program in January, the founders received a $500,000 equity investment from the accelerator to begin developing their AI platform. Other VC firms participated in the pre-seed round and invested an additional $1 million in the startup. These firms included a16z Scout Fund, Andreessen Horowitz’s fund for early-stage investments, as well as Firestreak Ventures and Pioneer Fund

It’s not surprising. Gangwani and Bansal’s platform is designed to redefine scientific discovery without extensive human interaction. So far, the prototype is built and is in private use by academic researchers, computer scientists, and computational biologists, Gangwani told CO—. As he explained, “The goal is to train the AI models to produce genuine scientific breakthroughs and eventually license the technology to pharmaceutical or biotechnology companies.” 

AI dramatically lowers the cost of research, Gangwani said. In theory, AI agents allow a small team of scientists and engineers to achieve breakthroughs. “That is significant when you consider that global R&D [research and development] spending is around $2.5 trillion a year across academia, government, and industry,” including science, he said. “AI-for-science is a small but fast-growing share of that. It’s a trend we are well positioned for.”
