The Bellevue mobile software and services developer today filed for a $250 million IPO today.

Motricity's already working with the top U.S. wireless phone companies and has a presence in Europe and Asia. It's planning further international growth, including expansions in Southeast Asia, India and Latin America, "applying our expertise gained from the U.S. market and fully leveraging the capabilities and scale of the mCore platform," it said in the prospectus.

Proceeds of the offering could also be used for acquisitions. The company dramatically grew in 2007 when it acquired the mobile content business of InfoSpace for $135 million. That put the bulk of the company in Bellevue, where it moved its headquarters from North Carolina in 2008.

The company said it's planning to "gain additional scale and technology through opportunistic acquisitions that expand our total market opportunity, provide complementary technologies and solutions, and aid our international expansion efforts."

Outside investors who have funded the company own more than half the current shares, including Carl Icahn, who holds 21 percent and Advanced Equities, which holds 26 percent. New Enterprise Associates have 8 percent and Technology Crossover Ventures has 6 percent.

Chief Executive Officer Ryan K. Wuerch has 22,685,231, or 4.98% of the total.

Also disclosed in the prospectus are details of the company's rapid growth in recent years. Managing this expansion is one of the risk factors listed:

Our revenue from continued operations grew from $1.9 million
during the year ended December 31, 2004 to $103.2 million during the year ended December 31, 2008. We also increased the number of our fulltime
employees from 88 at December 31, 2004 to 338 at December 31, 2008.
