Based on a brand-new round of funding, smartphone-based taxi app Uber is now thought to be worth an unbelievable $17 billion.

The newly injected capital, to the tune of $1.2 billion, has made it second only to Facebook in funds raised before going public. It's an impressive feat made even more impressive by the fact that the company was founded in 2010 and in just four years has expanded to 128 cities in 37 countries around the world. 

Uber is thought to have raked in $200 million from $1 billion worth of revenue in 2013 alone, a number that's likely to grow once it begins actualizing plans to offer more varied transportation services.
