Xiaomi, a Chinese startup that helped pioneer the trend toward ultra-low-priced smartphones, is preparing for what would be the biggest initial public offering since e-commerce giant Alibaba's in 2014. The 8-year-old is a star among the Chinese unicorns, a term that refers to startup companies that are valued at more than $1 billion. It has a dedicated Chinese fan base and its media-savvy leader is an Asian celebrity. But it is untested outside the region. Xiaomi -pronounced "SHEE-YOW'-mee" -was founded in 2010 by CEO Jun Lei and seven colleagues who included veterans of Alphabet Inc.'s Google, Microsoft Corp. and Motorola Inc.

Their first smartphone, the Mi1 released in 2011, was an instant hit with little marketing. Consumers buzzed about its low price of 1,999 yuan ($305) and competitive quality. It helped to ignite an unusual fan culture on which Xiaomi has built its product development. Customers take part in design decisions by sending suggestions over social media. In 2013, Xiaomi sold more handsets in China than Apple. The next year, it became China's top-selling smartphone. The company later was passed in sales volume by local rivals Huawei, Oppo and Vivo. But after a slump in 2016, Xiaomi's growth rate outpaced other smartphone makers in the following year. While Samsung, Apple and Huawei saw flat or 10 percent growth or less in 2017, Xiaomi sales jumped 58 percent, according to IHS. Last year, the company had a 6 percent share of the global smartphone market, despite minimal presence in Europe and the United States.

However, Xiaomi lost money last year. A lot. The company reported a loss of 43.9 billion yuan ($6.8 billion) on revenue of 114.6 billion yuan. Even if the company turns that around, CEO Lei has promised to keep prices low for consumers by holding profit margins on hardware sales to 5 percent, a stance that might rattle investors. Xiaomi makes 90 percent of its revenue from hardware sales but calls itself an internet content company. It wants to make money by delivering services to the more than 100 million users of its connected devices and 190 million users who use its software MIUI.

The IPO is expected to raise billions of dollars -possibly the biggest haul since Alibaba raised $22 billion in 2014 -though forecasts of how much have declined. Investors are likely to value Xiaomi at $63-$68 billion, down from earlier expectations of as much as $100 billion due to its "low profitability," said Choi Won-seok of Shinhan Investment Corp. in a report.

Xiaomi is the rare Chinese brand that has succeeded abroad. In India, it unseated Samsung as No. 1 in smartphone sales. South Korean trendsetters love Xiaomi. Other Asian fans rave on YouTube and social media about Xiaomi air purifiers, suitcases and vacuum cleaners.

But can it stir similar enthusiasm among investors and Western audiences? A key challenge will be winning over U.S. and European consumers who might be more wary of Chinese brands. Another challenge is to show to investors that, like Google or Amazon.com Inc., it can make a profit from services, reducing reliance on handset sales.
