New York-based Flycell, which is a wholly owned subsidiary of Italian-based and publicly held Acotel Group (BIT: ACO), released limited financial results today, reporting that the first quarter was its best ever in the company’s four-year history. The mobile content company said it made $75 million in 2008, and revenue of $23 million in the first quarter, increasing 60 percent compared to the year-ago period.

Flycell continues to grow despite the fact that analysts are expecting demand for ringtones, graphics, and other mobile content to decrease over time as consumers become more sophisticated and learn ways to load the content on their phone without a middleman. Alberto Montesi, Flycell’s CEO, said he doesn’t know why they continue to grow if that’s the trend. Montesi: “We haven’t felt any contractions in demand. Not in the U.S., and we are growing in all the emerging markets…The demand for this product is very high. We are selling something that’s not easy for people to understand, how to download, etc. It’s usually hard for people, but I give them a nice experience, and walk them step-by-step through the process.”

Montesi said most their growth is from launching services in new markets. Today, the company’s off-deck subscription services are in seven markets, and while the U.S. is still it’s largest, Montesi said it won’t be for long. Other countries, while starting at a smaller base, are seeing strong year-over-year growth. In this year alone, the company plans to launch three new markets, including South Africa and Argentina. It is also operating in Mexico, Canada, Spain, Italy and Brazil. The company also recently launched an unlimited plan. For $19.99 a month, users can download as much content from any of the company’s catalogs, including ringtones, graphics, or games. Typically, the company charges $9.99 for 10 pieces of content.
