Back in 2005, MIT engineering graduate student Limor Fried was procrastinating hard on finishing the "busy work" of her final thesis by building her own portable music player. From scratch.

Her classmates couldn't help but notice her personal style, and they asked how they could build their own. Fried started selling little kits with all the electronics they needed to get started.

It became a nice little business for Fried, and she saw the opportunity to turn her passion for teaching people to make stuff into an entrepreneurial opportunity.

Later that year, Fried would move to New York City to found Adafruit Industries — taken from "ladyada," Fried's long-time online moniker, itself a tribute to Ada Lovelace, the 19th-century mathematician widely credited as the world's first computer programmer.

These days, Adafruit Industries rents a manufacturing facility in Manhattan's hip SoHo neighborhood that is larger than 15,000 square feet, where more than 85 employees design, build, and test an ever-expanding roster of do-it-yourself electronics kits and parts for novice makers up to more experienced experts.

"You can have a really good project experience within 15 minutes," Fried says.

In 2014, Fried says, Adafruit sold $33 million in products, and the company is growing at a steady clip of about 20% year-over-year. With some napkin math, that means Adafruit Industries is on track to sell about $40 million of product this year. And Fried is the sole owner.

'Everybody's getting raises and promotions'

Compared with the hockey-stick growth of some Silicon Valley startups, taking 10 years to get to $33 million in sales revenue may seem slow.

But Fried prides herself on never taking a dime of venture-capital funding for Adafruit Industries, meaning the company can pay its bills and focus on its main mission of helping people understand and build technology, without having to panic about whether it's growing fast enough.

"Slow growth is the goal," Fried says. "Everybody's getting raises and promotions."

Fried says she's glad not to be competing in the "disaster area" of venture-backed startups, many of which go bust or get bought for pennies on the dollar thanks to their seeming inability to manage their burn rate.

"I hope you have explosive growth, because you have to," Fried jokes of venture-backed startups. "We have savings — we can do math."
