Corona Labs, a Palo Alto-based firm that helps app developers build apps for multiple device platforms, has closed a $2 million financing round that will be used to grow its engineering team and worldwide business. The injection of capital is provided by existing investor Merus Capital — which put $1 million into the company three years ago — and a new backer, Western Technology Investment (WTI).

The company, formerly known as Ansca Mobile, was founded in 2008 by ex-Adobe pair Carlos Icaza and Walter Luh and it has long moved on from a sole focus on helping bring iPhone apps to market with speed. To date, the Corona SDK has been used by more than 150,000 developers worldwide who have created more than 20,000 games, apps and eBooks for iOS, Android, Nook and Kindle Fire devices.

The SDK helps developers bring their creations to market quickly — Corona says it is “ten times faster than alternatives” — and the company has another, related venture, which started in August when it launched Corona Enterprise, a system that helps build feature-rich apps.

Corona Enterprise has proven particularly popular with games developers — including Accel-backed Flaregames and GREE partner Mobicle – since it helps ensure that apps and mobile content is built with support for the latest requirements, such as screen sizes, resolutions etc. In essence the product brings big developer practices — such as testing and multi-platform support — to indie studios and small development teams.

“We’ve experienced tremendous growth since our initial Series A funding in 2009,” said Corona Labs CEO Luh. “Corona developers span the globe and build truly incredible mobile content each day.”

Commenting the new investment, Salman Ullah, co-founder of Merus Capital, said: “We’ve witnessed the company grow from its inception, becoming a leader in the mobile industry [and] we’re excited to further help the company achieve its mission of making mobile development easier than ever.”
