Startups vie for venture capital at annual event At the Demo@15 show this week in Scottsdale, Ariz., more than 70 startups will unveil new technologies, several of which tap the current interest for on-demand and software-as-a-service products.“Without a doubt [software as a service] has been poised to explode for a while,” said Josh Greenbaum, principal analyst at Enterprise Applications Consulting. “Salesforce.com has given it a good name; Siebel Systems, and their name, has added a further endorsement.”Demandware will introduce Demandware eCommerce, a hosted application for retailers who want to establish an e-commerce presence on the Web. Built on a reference application, the on-demand service will use an SOA (service-oriented architecture) to offer companies e-commerce components and best-practices business processes in an effort to help them create unique e-commerce sites. Smart Online’s OneBiz Conductor will also use a Web services architecture as the backbone of its on-demand ERP service for SMBs. The product leverages its 25 business applications and can be integrated with third-party ERP solutions.Also at the show, ImpactEngine will launch a multimedia software-as-a-service application. The service will allow users to create so-called “engines” — multimedia content that can be reused on Web sites, online ads, presentations, and e-mails.Nsite will demonstrate Nsite SmartForm, which allows nontechnical users to customize company forms on the Web to match their own unique requirements.
