A fire in a restaurant behind a house in San Jose cost the owners tens of thousands of dollars and nearly took lives, but for 13-year-old Shanaya Gill it became a starting point. Instead of simply buying a new smoke detector, she asked herself: why are safety systems so expensive after a disaster and so cheap before it?
Shanaya created a device based on a thermal camera and AI that detects heat sources without human presence and sends an SMS alert within two minutes. Accuracy reaches 97 percent, and the price is about 20 dollars. In 2023, the project won 25 thousand dollars at the Thermo Fisher Scientific Junior Innovators Challenge. In 2025, she officially launched the startup Vigil Inc., planning mass production by the end of the year. The U.S. Fire Administration is already helping to attract funding for scaling.
The economics of fires in California is harsh: annual damage amounts to billions, and insurance payouts and recovery hit the pockets of families and municipalities. Early detection reduces these costs many times over — one timely signal can save hundreds of thousands of dollars on firefighting and repairs. Vigil turns a personal tragedy into a product that solves the problem at the household level, not just for large corporations or authorities.
The startup's financial model relies on low cost and scalability. Unlike traditional systems for 300–400 dollars with a subscription, Vigil does not require complex infrastructure and is patented minimally to get to market faster. The girl learned to code using ChatGPT and YouTube, minimizing development costs. This is a classic example of a lean startup, where personal capital — time and persistence — is converted into intellectual property and future income.
Interests intersect here: insurers benefit from reduced payouts, cities from fewer fire calls, and young entrepreneurs gain access to grants and investments. Support from the U.S. Fire Administration opens doors to federal contracts, turning a school project into a potentially multi-million-dollar business. The risk, however, remains: mass production requires capital, and competition with major players could squeeze margins.
As the old saying goes, "better to prevent than to cure" — in financial terms, this means that investing in prevention is always cheaper than the consequences. Vigil shows how one teenager from California turned a fear of fire into a tool that could protect millions of homes and save billions of dollars for society.
