Noa Mintz is a freshman in high school, and she's taking the New York City childcare scene by storm, catering to a huge urban market.
Now 15, Mintz started Nannies by Noa in August 2012. She said she saw a need through her own experiences growing up in the city.
"My mom went through a lot of nannies. We had a lot of discussion, and I came to the conclusion that the agency she was working with didn't know what a New York nanny was. ... It's sort of a vibe," Mintz said Friday in an interview on CNBC's "Squawk Box."
Good nannies—especially in a major city like New York—are a notoriously tough commodity. Depending on the job description and the family's income level, a caregiver can earn anywhere upward of $400 per week. For those assigned to wealthy families, a nanny can easily command six figure salaries.
"I knew what kids wanted in a nanny. I had the unique perspective. So I set out to start with a couple family friends," Mintz said. "Then people thought it was a really good idea to have a kid helping them. And trust for the brand grew."
