Xiaomi is a relative new kid on the block when it comes to smartphones, launching its first in just 2011. The Chinese manufacturer has since seen a meteoric rise to success that puts it currently as one of the world's largest smartphone vendors by volume. Xiaomi's main success comes from its native China, and in recent years, the brand has made it big in the Indian market thanks to its range of budget Redmi devices.
Away from smartphones, Xiaomi makes apps, smart TVs, fitness bands, air purifiers, robot vacuums, and even a smart rice cooker. But the thing it's probably most well known for away from actual phones is the software that runs on them. MIUI predates the first Xiaomi smartphones and is a complete re-working of Android as we know it. It's also available readily for non-Xiaomi smartphones.
Perhaps the most famous employee at the Chinese manufacturer is Hugo Barra, formerly of Google. Barra was formerly a high-up on the Android team but left to take up a position as Global VP at Xiaomi.
