After Steven Yang left his coveted job at Google, he asked his mother whether he should take venture-capital money to fund his business idea. If his online consumer-electronics enterprise was a risky bet, she told him, go with the venture capitalists. But if building the business into something great was his destiny, he instead should use her money from a pharmaceutical career in China. So Yang combined his Google money with his mom\u2019s, and with less than $1 million in seed capital he moved from California to Shenzhen, a hub in southern China for technology companies. Seven years later, Anker Innovations Technology Co. sells products ranging from smartphone chargers to portable power banks on Amazon.com. And it\u2019s getting even bigger after recently reaching a deal to put products in almost 4,000 Walmart Inc. and 900 Best Buy Co. stores in the U.S. Recent trades on China\u2019s over-the-counter New Third Board market valued Anker at about $1.1 billion. Yang, 36, and his wife have a combined stake of about 54 percent, according to a Bloomberg analysis of the company\u2019s first-quarter report for 2018. Anker offers chargers that are alternatives to those from companies like Samsung Electronics Co. or Apple Inc. and come with proprietary PowerIQ technology, which detects each phone\u2019s maximum wattage to help minimize charging times. Yang also has branched out into just about every other smartphone-related gadget, including cables, headphones and wireless charging pads. And he\u2019s making household products like robotic vacuums under the Eufy brand. \u201cWe really put a lot of love, and hate, into our products,\u201d Yang said, referencing the year-long tedium of shrinking the vacuum robot down to 2.85 inches in height so it could fit under couches. Sweet Spot As smartphone maker Xiaomi Corp. prepares for a Hong Kong initial public offering, Yang figures the timing may be right for him, too. He\u2019s studying the possibility of going public in China, Japan, Hong Kong or the U.S. If he decides to proceed, he could have his work cut out for him. As of early May, two-thirds of the 21 China tech IPOs in the past year were below their issue price. Xiaomi had been targeting an eye-popping $100 billion valuation for its debut, but now is eyeing $60 billion to $70 billion, people familiar with the matter told Bloomberg earlier this month. Yang has taken on several funding rounds over the years, and investors are coming knocking again. Jumei International Holding Ltd., a U.S.-listed Chinese beauty e-commerce firm, bought a 60 percent stake in Anker\u2019s powerbank-rental unit last year for 300 million yuan ($47 million). Anker\u2019s revenue surged 56 percent in 2017 to 3.9 billion yuan, and profit grew 9.9 percent to 356 million yuan, according to its annual report. It has offices in Seattle, Dubai, Tokyo, Shenzhen and Changsha, China, according to its website. Almost half of its revenue comes from the U.S., but China sales doubled last year. Like many China tech companies, Anker is also following President Xi Jinping\u2019s goal of making the nation a leader in developing artificial intelligence, and it has a lab for developing facial recognition for security purposes. Tech Gaps Its expansion has come as Yang seized opportunities created by gaps in the technology industry. In the smartphone business, he targeted the opening between Apple\u2019s expensive chargers and low-quality, white-label replacements. Anker occupies the space between five-star and three-star Amazon reviews (most Anker products have about four). That is Yang\u2019s sweet spot, where he creates an accessory that isn\u2019t the most expensive but still is of good-enough quality to win consumer trust. That also means his brands must contend with fierce competition online. "Selling via Amazon is absolutely still a viable strategy for smaller brands," said Benjamin Cavender, analyst at China Market Research Group. "However, Amazon is increasingly selling its own brand products via its marketplace, which means that smaller companies need to be very aggressive about providing good products and service at attractive price points." These days Yang is also hoping tensions around a trade war between China and the U.S. don\u2019t escalate. Nearby is the Shenzhen campus of telecommunications giant ZTE Corp., which had to shut major operations after a Trump administration ban on its ability to buy U.S. technology. Trump earlier this month tweeted that he was working on a way to get ZTE back into business. Shenzhen Hub One of Anker\u2019s great advantages is that it\u2019s embedded with the supply chain in Shenzhen. The city was a fishing village just four decades ago, until Communist Party Chairman Deng Xiaoping turned it into the country\u2019s first Special Economic Zone as part of China\u2019s economic opening. It blossomed into the world\u2019s electronics manufacturing hub, with the vast majority of consumer electronics produced there. It\u2019s now evolving again as entrepreneurs like Yang follow big names Tencent Holdings Ltd. to Huawei Technologies Co. in setting up shop. Yang recruits from a large talent pool in Shenzhen, and he\u2019s hired some fellow ex-Googlers: the former China sales head and two product developers. Each of the company\u2019s offerings is designed by fiefdom-like teams that sometimes crowdfund their early-stage prototypes. At the Shenzhen office, they\u2019re seen scribbling notes onto transparent conference walls. Automated System Yang grew up in central China\u2019s Changsha and studied computer science at Peking University and then at the University of Texas at Austin. He developed his programming skills in five years at Google. Two years before leaving the company, he built an automated system for his girlfriend (now his wife), who was selling women\u2019s accessories and other products on Amazon as a side business. The system fixed inventory, logistics, fulfillment and tracking of sales, and it began fulfilling 300 orders a day. But he had to learn hardware from scratch when he started Anker. Mobile-phone batteries haven\u2019t changed all that much since before smartphones. Dying batteries remain a bane of the digital age, and researchers are already looking for solutions. So, although Anker\u2019s chargers are a best-seller, Yang is already preparing for the day they will be obsolete, pushing products like Anker\u2019s $14.99 wireless charging pads. He learned the importance of constantly looking ahead from his mother, who gave up a job at a state-owned company to set up her own pharma business. \u201cShe said: If you think this business is going to be something, then take my own money," Yang said. Now, to keep the business growing, Yang will have to stay relevant in a fiercely competitive global market.
