With the rise of selling platforms like Shopify, Amazon and Etsy, young entrepreneurs are getting an early start at making their mark.

Take Zandra Cunningham, of Buffalo, NY, who at age 9 created Zandra Beauty, an all-natural skin-care line aimed at teen girls.

“I was obsessed with lip balms and asked my dad to buy some, but he told me ‘No — make your own,’ ” says Cunningham , now 18. “I researched YouTube and made some in simple bubble-gum flavor, using a kit. I passed it around at church and a lady gave me a dollar. I knew I could make money off it.”

Cunningham next developed soaps, sugar scrubs and body butters. Her products were a hit at area vending events, but not all artisan markets took her seriously, so, “I set up an online shop on Etsy,” she says.

Cunningham became the platform’s youngest seller to compete in its Open Call competition, during which sellers pitch buyers of retail stores.

“Paper Source picked me and placed an order for 8,000 units,” Cunningham says.

Participation in a KidBiz summer program at SUNY Buffalo State taught her business etiquette. She also completed an adult entrepreneurship program , through which she developed a business plan, gained a mentor, and defined her business goals.

In 2013, Cunningham became a girls rights ambassador, for a women empowerment organization, prompting her to incorporate social responsibility into her business.

“Finding out that girls are being enslaved and not allowed to go to school led me to donate 10 percent of my proceeds to this cause,” she says.

Cunningham was eventually featured on the “Today Show,” catapulting sales.

“By 2016, we grossed $100,000 in sales, and for 2018, we’re anticipating $1 million,” says Cunningham.

Today, both of her parents work for her business full-time — Dad is the CFO and “Mom does marketing and operations,” says Cunningham, who remains CEO.

She’s currently a freshman at SUNY University at Buffalo, majoring in business.

“My goal is to transfer to an Ivy League school and get my MBA. I want to grow my business and learn skills I can to apply to my company,” she says.

To other young, aspiring business owners, Cunningham says, “Focus on your hobbies and passions. Ask yourself if the product you want to market already exists. Is your product an improvement on an existing product? How is it unique? If you can’t answer any of these questions, you need to think of a spin. If customers don’t need it, it won’t last that long.”

Parental support can be invaluable for an entrepreneurial-minded child.

When 7-year-old Charlotte Dowell of Larchmont, NY, expressed an interest in fashion, her mom, Elise, enrolled her in a sewing class and let her select outfits to wear to work.

“She’s picked out her father’s ties since she was 2. She loves talking to people about fashion and styling,” says Dowell.

Charlotte has her own business cards that read, “Styled by Char,” which has netted her some clients.

“I told my babysitter to wear a blue top, with jeans, a ponytail and red lipstick,” says Charlotte.

To further her interest in business, Dowell is looking toward camps and kids business classes at the local library. “We’ll support her and are letting her drive this,” she says.

When Brookline, Mass.-based fifth-grader Zoe Kalish couldn’t find shoes with enough sparkle, her mom bought Converse on sale. “I glued Swarovski crystals to jazz them up,” says Zoe. “It’s fun to express yourself through clothing.”

With her mom’s assistance, she launched DazzledByZoe.com, through which she sells brand name, “bedazzled” shoes in baby and child sizes for between $15 and $75.

“People give me compliments,” says Zoe. “When they’re having a bad day, adding sparkle to shoes puts a smile on their face.”

One day, she hopes to donate a pair of shoes, for every one sold, to children with prosthetic limbs, to make them feel better about themselves.

Her advice to others starting out? “Have a big idea and don’t let anyone say it’s not good. Keep on doing it.”

Sometimes, a child’s undeniable, innate talent is the driving force for a business.

Less than six months ago, 6-year-old Noah Snow, who loved to sketch faces, was introduced to the work of the famed, late American landscape painter, Bob Ross.

“I watched videos of him on YouTube and Netflix,” says Noah. “I love the way he paints — mountains, the sky.”

Soon, Noah started painting, too.

“By his third painting, my husband and I knew it was really good,” says Noah’s mom, Lauren. “I shared his work on Facebook, and family and friends asked how they could get one of his paintings, so we created an Etsy shop.”

As fate had it, a local art studio was offering Bob Ross paint-technique classes.

“Noah’s art teacher is lovely and has been through extensive training. Noah is getting better and better,” says Snow. “His teacher says he was born to do this, that it’s a gift from God. He’s become her little protégé.”

Noah has featured in Newsday, on Fox 5 NY and is slated to appear on Steve Harvey’s show. Paintings sell for an average of $25 to $50 on average. So far, his mom says, he’s made $1,000.

“Noah likes the fact that if he wants a $25 paintbrush, he can go into his wallet and pay for it,” says Snow.

Keeping up with orders has become a family affair. Noah’s older brother, Preston, age 9, prices the paintings and wraps them up for shipping.

“We give Preston $5 per painting sold,” says Snow.

For Noah, all of the attention has been fun.

“I like sharing my work,” he says. “I’d like to teach people and kids how to paint. I’d like to be the next Bob Ross.”
