Goldman Sachs has put a tidy $70 million in AppSense.

Obviously it pays to wait. It's the first outside investment the already-profitable UK-based user virtualization house has taken in since it got started in 1999.

It's not telling what the valuation is on the minority position, but Goldman gets a board seat and there's obviously an IPO down the road once AppSense gets more meat on its bones.

The company says it will use the money to accelerate its growth in a market expected to be worth upwards of $2 billion by 2015, pushing further into the US and expanding internationally.

AppSense claims 4,000 customers including blue-chips like British Telecom, JPMorgan Chase, United Airlines and the Centers for Disease Control and Prevention (CDC).

It says it sold 1.5 million user licenses last year with orders up 80% last quarter.

It saw 60% revenue growth to $47 million last year, increased its workforce by 40%, and partnered with Microsoft lately.

It expects more of the same with the growth of cloud and mobile device platforms and the shift off the desktop.

User virtualization is supposed to enable the same user experience across devices and platform and let IT manage the user independently of the underlying widgetry. AppSense virtualizes the user, which is supposed to make trying to manage the welter of separate devices underneath unnecessary. It figures people nowadays have at least three devices.
