Xiaomi is likely to be the biggest smartphone maker you've never heard of.
The company – often dubbed "China's Apple" by analysts - has had a rapid rise in 2014, coming out of nowhere to knock Samsung off the smartphone top spot in China and propelling itself to number three smartphone vendor globally, according to IDC.
Investors are flocking to put money into Xiaomi, a company that was only founded in 2010. It raised more than $1 billion in the latest round of funding, according to the Wall Street Journal, giving the Chinese company a $45 billion valuation – bigger than Uber, Netflix and Twitter.
