The former philosophy professor shares how experimentation, persistence, and people-first leadership turned a simple phone grip into a billion-unit accessory business.
The story behind PopSockets reads like a classic startup myth.
More than a decade ago, David Barnett, then a philosophy professor, was simply trying to manage his headphone cord. That small frustration led him to create a simple phone accessory that would eventually become one of the most recognizable mobile gadgets in the world.
In a conversation with the Equity podcast, Barnett reflected on the lessons learned while building the company—from early manufacturing disasters to the decision to grow the business without venture capital.
An Idea Born From Everyday Frustration
PopSockets started as a personal workaround.
Barnett needed a better way to hold and wrap his headphones while using his phone. His solution was a small expandable grip that attaches to the back of a smartphone, doubling as both a handle and a kickstand.
Simple idea. Massive impact.
But the early path to success was anything but smooth.
Learning Business the Hard Way
Barnett entered entrepreneurship with almost no traditional business experience.
“I was a philosophy professor, so I had no experience with manufacturing,” he said.
That knowledge gap led to several early hurdles:
- Manufacturing defects in early product batches
- Limited understanding of finance and accounting
- Months of burning through savings without revenue
The setbacks were constant. Barnett described “wave after wave of manufacturing defects” during the company’s earliest days.
Still, he kept experimenting.
The Retail Breakthrough
One pivotal moment came in a local toy store.
Barnett regularly visited the store to observe how customers interacted with the product on shelves.
At first, sales were slow and inconsistent.
After making design adjustments to the PopSocket itself, something changed.
“That was the point where I thought, ‘Okay, this could work in retail,’” Barnett said.
Once the product clicked with customers, demand began accelerating quickly.
Growing Without Venture Capital
Unlike many consumer hardware startups, PopSockets never relied on traditional venture capital funding.
Barnett chose a different path.
The company focused on:
- Organic growth through retail sales
- Maintaining control over the brand and product
- Protecting its intellectual property aggressively
That independence helped PopSockets avoid some of the pressure that venture-backed startups face to prioritize rapid growth over sustainability.
Scaling the brand wasn’t always straightforward.
Barnett also described a dispute with Amazon that led him to temporarily remove PopSockets products from the platform.
The episode highlighted a common challenge for consumer brands: balancing the reach of major marketplaces with the need to protect brand identity and pricing control.
Knowing When to Step Aside
Eventually, Barnett reached another important decision—stepping down as CEO.
After years of building the company, he concluded that the next stage of growth required a different leadership style.
His biggest lesson from the journey?
Leadership ultimately comes down to people.
“The greatest lesson I’ve learned is that it’s all about the people,” Barnett said.
When choosing a successor, that principle became his main priority.
PopSockets’ success underscores a powerful startup lesson.
Not every breakthrough comes from deep technology or venture funding. Sometimes the biggest hits emerge from solving a tiny, universal problem—and relentlessly refining the solution.
For Barnett, the formula was simple:
Observe customers, improve the product, and surround yourself with the right people.
TL;DR:
PopSockets founder David Barnett, a former philosophy professor, built one of the world’s most viral phone accessories after starting the company in his garage. Despite early manufacturing failures and no venture funding, the brand scaled through retail success, product iteration, and a strong focus on leadership and team culture.
