Xamarin, a startup that’s all about enabling mobile developers within the enterprise, has raised a second round of institutional funding.

The $16 million round was led by Lead Edge Capital, with participation from previous investors Charles River Ventures, Ignition Partners, and Floodgate.

The company also announced today that it has 20,000 paying developers and a total of more than 350,000 devs in its community.

“In the very near future, every business process and customer interaction will happen on a mobile device,” said Xamarin CEO and cofounder Nat Friedman in a statement on the news.

“Xamarin’s unique approach of enabling businesses to rapidly deliver fully native apps for multiple device platforms has resulted in incredible revenue growth and market momentum.”

Recently, Xamarin gave C# (a.k.a., hardcore Microsoft-bred developers) the ability to build native iOS and Android apps inside Visual Studio with Xamarin 2.0, a bundle of products including a new integrated development environment, Xamarin Studio; Xamarin.iOS for Visual Studio and a plugin for Visual Studio that enables cross-platform mobile development; and the Xamarin Component Store, where users can buy and sell code components of apps to speed up development and make a bit of money.

Xamarin’s Series A took place almost exactly one year ago. The $12 million round allowed the startup to begin addressing the mobile developer shortage within the enterprise.

The startup is based in Boston, Mass., and was founded in 2011. Its clients run the gamut from megacorporation National Instruments to music startup Rdio.
