At age 12, Bella Lin had a downside. Her guinea pigs had been disappearing.
In these days, Lin let her three guinea pigs roam her dad and mom’ grassy, fenced-in yard simply exterior of San Francisco. It was higher than the choice, she thought: The two-pound creatures “regarded depressing” in their cramped, “prison-barred” cage, Lin, now 17, tells CNBC Make It.
She assumed the primary, Snoopy, had escaped and she or he continued letting her guinea pigs exterior — till her dad watched an eagle fly away with one other, she remembers. Determined to maintain the pets out of conventional cages, she began drawing prototypes.
Lin, a senior at Khan Lab School in Mountain View, California, went by way of a number of fashions and invested roughly $2,000 from her savings to launch her side hustle GuineaLoft on Amazon in November 2022.
It offered practically 11,000 cages and introduced in greater than $410,000 final yr — roughly $34,000 per month, on common — in accordance to paperwork reviewed by Make It.
In addition to a full tutorial course load, extracurriculars and faculty purposes, Lin works about 20 hours per week on GuineaLoft, she says. Here’s how she constructed a side hustle so profitable that she’s contemplating delaying faculty to consider her enterprise.
An unprofitable side hustle led to an ‘epiphany’
Lin informed her dad, a pc programmer, that she wished to create a higher cage. He had a connection to a family-owned manufacturing facility in China by way of a former consumer, and he made an introduction, Lin says.
After a yr of mocking up prototypes, Lin obtained distracted by a totally different concept: She wished to promote athleisure for ladies at a lower cost level than massive, fashionable manufacturers. She researched, discovered one other manufacturing facility in China, related with it, and made a marketing strategy to promote leggings beginning at $23.
GuineaLoft’s first prototypes had been constructed from her dad and mom’ eating room desk utilizing workplace provides, Lin says.

That side hustle, referred to as TLeggings, launched in July 2019. It introduced in roughly $300,000 in income in 2020, she says. It additionally earned Lin a spot at BizWorld, a project-based entrepreneurship program for 16- to 22-year-olds.
She accomplished a 12-week curriculum and labored with a enterprise mentor, however failed to win the pitching contest — and any prize cash — on the finish of this system. It was certainly one of a few indicators that TLeggings was really fizzling out: Despite the lofty income numbers, the corporate was by no means worthwhile, and Lin struggled to sustain along with her rivals.
She shuttered it in early 2022, and refocused on GuineaLoft.
“I had a bizarre epiphany [where] I type of realized there are a lot of different firms making an attempt to [make leggings],” Lin says. “There was no innovation there, whereas with GuineaLoft, I might fill a actually large hole in the market.”
Tinkering between lessons and late at evening
Lin realized her early prototypes had been promising, however imperfect.
Traditional guinea pig cages are made with bars, roofs and both tarp or plastic bottoms. They are tough to clear, Lin says, and infrequently reek of excrement.
Her early glass, open-floor enclosures allowed for extra visibility and mobility, and featured a two-tiered backside. Dirty bedding might be pushed into a detachable plastic tray. But the glass was too costly to ship, and her smaller guinea pigs’ toes obtained caught in the ground.

Lin rearranged her schedule so she might do her homework in between intervals in school. She stayed up late to analysis and nearly take a look at merchandise along with her six-person crew in China — a manufacturing lead who works for the manufacturing facility, and 5 full-time GuineaLoft workers who’d beforehand labored with Lin’s dad or the manufacturing facility’s management.
Those six individuals supply, manufacture, bundle and {photograph} the merchandise, says Lin. She manages GuineaLoft’s product design, pricing, advertising and marketing — TLeggings taught her a lot about social media in explicit, she says — and total enterprise technique.
Ultimately the corporate went with acrylic as a substitute of glass and constructed replaceable bottoms from biodegradable, wax-coated paper — comparable, Lin says, to “airplane barf luggage.”
The bottoms are simple to throw out, which is sweet for enterprise: Once happy GuineaLoft prospects run out, they’ve to come again to Lin’s Amazon retailer to restock.
Winning a $10,000 competitors
The manufacturing facility produced 100 cages in its first batch. Lin was elated when three offered in the primary couple of hours.
Within two weeks, GuineaLoft all 100 had been gone “with no advertising and marketing,” she says. She re-applied to BizWorld final yr, and received $10,000 in funding funds from the pitching competitors. That cash will go towards including equipment and new cages for various kinds of small pets, like rabbits and hamsters, she says.
Lin has owned guinea pigs for years, and has stored up to 10 at one time, she says.

The firm’s 25% revenue margin on particular person cages is instantly reinvested into advertising and marketing, viewers analysis and the event of recent merchandise, Lin says.
That means she’s not pocketing any money for herself but — however whereas she’s making use of to schools, she’s additionally contemplating taking a hole yr after graduating highschool to go to the manufacturing facility in China, study extra about manufacturing and develop her enterprise.
“Witnessing the tangible results of [GuineaLoft cages] by way of buyer evaluations and emails is empowering,” Lin says. “As somebody who as soon as positioned nice emphasis on tutorial validation, the success … of [my side hustle] has boosted my confidence in navigating life past highschool.”
