Twitter made its S-1 filing available to the public on Thursday, finally shedding some light on its initial public offering plans.

The company has seen rapid growth recently. In 2012 the company saw an increase in revenue of 198 percent to about $317 million and a net loss decrease of 38 percent to about $79 million, according to the filing.

According to the filing, Twitter, which plans to trade under the ticker TWTR, has 250 million monthly active users, 100 million of those are daily active users.

The company said in the filing that mobile is the primary driver of its business and that 75 percent of the monthly active users access Twitter from a mobile device.

There's still a lot of information that is missing from the filing, like the number of shares the company plans to offer and the price of the shares, but it does give some insight into which investors stand to make the most money off the offering.

Jack Dorsey has a 4.9 percent stake in the company, Evan Williams has a 12 percent stake and Peter Fenton, a Twitter board member, has a 6.7 percent stake.

In September, the company announced it had confidentially submitted documents to the U.S. Securities and Exchange Commission with plans to go public, but Twitter didn't reveal anything else about its IPO plans. The filing was made under the JOBS Act, which allows companies making less than $1 billion in revenue to work with regulators on IPO plans before actually making it public.

The micro-blogging site has been valued at about $10 billion and is one of the most anticipated Silicon Valley IPOs since Facebook.
