Chen Chen ’16


Current Position: Co-founder and CEO, Saphlux

By Dana Cook Grossman

Ten years ago, Chen Chen was a rising mechanical engineer. After completing his undergraduate degree in his native China, his doctorate at Auburn, and a postdoc at Harvard, he landed a job doing R&D for Schlumberger, a $32-billion-a-year provider of technology to the oil and gas industry. He immediately made a mark by developing a new way of cutting drill bits that lasted up to eight times longer. “We won a number of big awards,” Chen says, “and the product is making Schlumberger probably billions by now.”

But Chen himself has taken a different path. Today, he’s a graduate of Yale SOM and the cofounder and CEO of a startup called Saphlux, which develops and manufactures components for next-generation LEDs and lasers. He’s now juggling design, production, marketing, vendor negotiations, and client relations. He’s drumming up financing for the firm ($11 million and counting to date). He’s jetting half a million kilometers a year in the process. And he’s enjoying every chaotic minute of it.

Ironically, it was his very success at Schlumberger that led to his leaving there. Watching the commercialization of his drill bit invention opened his eyes to how a development spreads after it leaves the lab. “That was a very big evolution for myself,” he says. “I realized I can transform an idea into a product and benefit many people. It made me think maybe I can do bigger things instead of just technology.” 

He decided he needed to know more about business to make that leap. So in 2014, he left Schlumberger and began an MBA at Yale SOM. He figured he’d likely start his own company eventually. But “eventually” turned out to be within weeks of his arrival in New Haven. He met Yale engineering professor Jung Han at a panel discussion for SOM students, the two hit it off, and in short order the focus of Han’s research became the core of Saphlux’s product line. 

That product is a semiconductor wafer made of innovative materials that eliminate polarization and “significantly boost…output power, efficiency, and wavelength stability,” as the company website explains it. 

Chen spent the rest of his two years at Yale SOM taking every entrepreneurial class he could, while working with Han to launch the firm. During winter break of his first year, Chen started lining up financing, and by the time he graduated in 2016 the firm had its first product ready to go. “It was quite hard, I have to admit,” Chen says. He thought about taking a gap year but ultimately toughed it out. He’s effusive in his appreciation for what he learned at Yale SOM and the support he got from the school’s Program on Entrepreneurship, if regretful that his focus on starting Saphlux kept him from spending more time with his classmates.

Chen was already an accomplished engineer, but the school gave him the management fundamentals and the leadership skills to run a business. 

“That knowledge base is very precious for me,” he says. “If I hadn’t gone to B school, if I had just started my company as an engineer, I think I would have made so many more mistakes.” Chen learned the nuts and bolts of financing and building a new company, and got a better understanding of the subtleties of managing people—including himself. “I think that’s very important, the leadership part. I think that was crucial for me at SOM.”

Meanwhile, he was taking advantage of the expertise that surrounded him. “I really got a lot of help from my professors and also my classmates—many of them had experience in financing ventures, in different fields,” he remembers. 

Jennifer McFadden ’08, Yale SOM’s associate director of entrepreneurship, was a particularly important mentor. “I still meet with Jennifer in the entrepreneurship program quite often,” Chen says. “It’s so important to have someone outside the company that knows you and the company well to give you suggestions.”

Compared to Schlumberger, Saphlux is still tiny, with about 30 employees. But it is a rising star. It counts among its customers “a lot of big names,” says Chen, like Philips, Osram, Mitsubishi, and Sony. 

“My customers say we’re the only company doing this in the world,” he adds. “They admire what we did. There’s a lot of risks, technically and businesswise. But we’ve come far. 

While most young companies start in a local market before even thinking about expanding globally, Saphlux was entering a field where a global approach was required. 

“One thing we did uniquely is we started internationally,” Chen explains. “The semiconductor industry is so mature that a lot of companies in the supply chain are global. So our vendors were from Japan, China, Korea, Taiwan, U.S., all different places, even from day one.” That means a grueling travel schedule for Chen. During one recent month, he flew from New Haven to Texas, then to two cities in California, three cities in Japan, four cities in China, on to Korea and Taiwan, and finally back to the U.S.

Saphlux itself now has a global footprint, with headquarters in Branford, Connecticut, a few miles from Yale, and a manufacturing facility in Xi’an, China, that has boosted the company’s output enormously. “When we had a single wafer machine in the U.S., we could make roughly 30 2-inch wafers a month” Chen says. “Now we can make more than 10,000 a month. And we can easily expand our capacity further.”

But Chen is always looking beyond manufacturing and sales. “We always want to be the company that provides the next-generation materials. If someday Saphlux stops developing new technologies and starts being just a manufacturing company, I think I’d get bored.”

The course he’s charted isn’t easy, he’s quick to admit. “When I talk to current SOM students who want to do a startup, I tell them, ‘If you don’t really enjoy this, a startup is not the best choice, because you suffer a lot.’ There’s so much uncertainty—you ride a roller coaster every day.

“As an entrepreneur and a CEO,” he explains, “if a problem comes to you, it’s always a hard problem. The easy ones, your employees have already solved. So you’re forced to evolve and learn pretty quickly. But that’s what I enjoy most.”

Not quite five years into his entrepreneurial journey, Chen sees himself staying the course with Saphlux. “We did a study showing that the financial return in partial ownership is not as good as if you do an IPO or licensing,” he says. But he and Han are fine with that. “We want to develop a product instead of just licensing it or selling out to a bigger company,” says Chen.

“I tell people that when my learning curve gets slack, that’s when I leave. I think that’s the reason I left Schlumberger. My learning curve is now very steep. And I’m very happy.”
