Dozens of products were launched on day one of the DEMO conference where the emerging technology companies were grouped together in cloud, mobile and enterprise categories. Day two featured social and consumer product pitches, and on both days, the DEMO 2012 team pulled together a group of investors to give some quick feedback on some of the apps and devices.

In all, there were 40 products pitched on day one, and there was also a segment for a group of eight young entrepreneurs to practice their 90-second idea pitches. It's called the alpha pitch, and the students promote their ideas for a chance to win a full college scholarship.

Here are some of the other highlights from the cloud and enterprise category product launches from day one of DEMO 2012:

Fusion-io API for ioMemory

Fusion-io is a larger startup, unlike so many of the DEMO 2012 companies, and today it announced its new ioMemory API that some of those new startups just may wind up using someday.

The new developer toolkit allows native access to the flash memory based servers and claims to be super fast, energy efficient and a perfect fit for the onslaught of big data that new apps will no doubt begin to use to their advantage.

Fusion-io pitched its product demo in a minutes-long segment as many other companies did who are vying for potential angel investor interest. The DEMO conference People's Choice award winner also walks away with US$ 1 million of free advertising from DEMO sponsor International Data Group.

Hazelcast

Hazelcast ties several servers together for speed and scalability. In this example, three nodes are used.

Hazelcast was named one of three 2012 Cool Vendors by Gartner Research, and its open source database was unveiled at DEMO 2012. Server nodes are clustered together with Hazelcast, so that if one of them goes down, the data is already backed up on the others so nothing is lost during a crash.

piOS by Bluega

Bluega team shows off its new HTML5 based operating system called piOS.

piOS is an HTML5 based operating system that can be used in any browser environment. An easy way to achieve the same look across mobile devices, the Web-based system also offers a way for developers to add new apps using the same HTML5 tools.

I'll be looking at some of the other highlights from DEMO 12, so be sure to check back in for more companies to watch.
