Website language translation service myGengo has raised a $5.25 million Series A round courtesy of investors 500 Startups and Atomico (News - Alert), Business Insider is reporting today. MyGengo will reportedly use the investment dollars to grow its marketing, sales and engineering teams.

Tokyo, Japan-based myGengo (“gengo” is Japanese for “language”) works with companies to translate their websites in 15 different languages.

The company was founded in December of 2008 by CEO Robert Laing, who formerly headed a UK-based design agency called Moresided, and CTO Matthew Romaine, formerly an audio research engineer for Sony in the company's Broadband Applications Laboratories. (Romaine was also an English-Japanese translator for Sony.) MyGengo's clients today include Demand Media, eHow and Evernote (News - Alert). This Series A round reportedly follows a recent $1.75 million seed round.

MyGengo is unique because it works differently than most language translation services. The company uses uses crowdsourcing – a concept that puts tasks out to a pool of people worldwide – to create a worldwide pool of 1,500 freelance translators. (To become part of the translation source crowd, translators must first pass tests before becoming qualified to work for myGengo.)

There is a separate test for each level of service myGengo offers: Standard, Pro and Ultra. MyGengo offers three products built off of this core platform: Translate (the text translation) String (a localization management tool) and the API (application programming interface), which allows developers to integrate myGengo’s translation platform into third-party applications or Web sites.

MyGengo is reporting that revenue is up 44 percent year-over-year this year, and the service has just translated its 15 millionth word.
