Ten Startups Share Their Wares at TechStars Demo Night

machine, and you continually feed it preferences and you get back a personalized radio stream based on those preferences,” Casci says. “Our machine is full of human DJs and they have built connections with artists, record labels, and listeners. It’s a real-time, shared experience. We are a social radio platform.”

Marginize
CEO: Ziad Sultan
Seeking: $350,000

If I had to write a check to just one company from TechStars’ 2010 class based on their presentations last night, this is the one I’d bet on. Marginize locates the social-media conversations going on around specific articles and pages on the Web and presents them right alongside those pages, using a special browser plugin (available so far only for the Google Chrome and Mozilla Firefox browsers). Social Web annotation schemes have been tried many times before—Third Voice, which had a short run from 1999 to 2001, was probably the first. But these previous attempts failed because they couldn’t solve the chicken-and-egg problem, says Marginize CEO Ziad Sultan, an entrepreneur-in-residence at Longworth Venture Partners (which is already an investor in Marginize). As he puts it, “You need great content to get thousands of users, but you need thousands of users to get great content.” The startup solves that problem by populating the Marginize popup screen associated with any given page with existing comments relating to that page from Facebook, Twitter, and Google Buzz. It then draws more users into those conversations by adding that page’s address to any new comments that users add using the plugin. You sort of have to see this in action to understand it—but trust me, it’s cool, and it’s exciting to me as a Web journalist because it has the potential to reunify social-media conversations with the objects of those conversations, such as news articles.

Mogotest
CEO: Kevin Menard
Seeking: $325,000

If you’ve ever spent days slaving to make your website look perfect in the Firefox browser, only to find that it looks completely different in Internet Explorer or Chrome or Safari, you’ll understand the need for Mogotest. It’s a Web-based service for testing the look and functionality of websites across multiple browsers, and even multiple platforms such as PCs and mobile devices, including Android, BlackBerry, and iPhone smartphones. When a user feeds in a site address, the Mogotest software automatically discovers all publicly accessible pages in that site and tests them for inconsistencies. When it finds problems, it can highlight them in side-by-side windows or by overlaying one site on the other, semi-transparently. Not only that, but the software will isolate the portions of the website’s HTML code that seem to be causing the inconsistencies. Priced at $45 per month for individuals, or $200 per month for workgroups, Mogotest’s system will be available to Web developers everywhere starting next month.

Monkey Analytics
CEO: Francesca Moyse
Seeking: Not fundraising yet

Some problems, like analyzing the trail of behavioral data that Internet users leave behind by clicking through the Web, are so data-intensive that they require more computing power or more expensive software than average professionals have on their company servers, let alone their laptops or desktop machines. Monkey Analytics lets users offload their big data-analytics jobs to the cloud. If an engineer needs to run an extensive numerical computation using MathWorks’ MATLAB program, for example, he or she can simply launch an instance of that software on Amazon’s EC2 computing service through

Before joining Xconomy in 2007, I was a staff member at MIT’s Technology Review from 2001 to 2006, serving as senior editor, San Francisco bureau chief, and executive editor of TechnologyReview.com. Before that, I was the Boston bureau reporter for Science, managing editor of supercomputing publications at NASA Ames Research Center, and Web editor at e-book pioneer NuvoMedia. I have a B.A. in the history of science from Harvard College and a PhD in the history and social study of science and technology from MIT. I've published articles in Science, Technology Review, IEEE Spectrum, Encyclopaedia Brittanica, Technology and Culture, Alaska Airlines Magazine, and World Business, and I've been a guest of NPR, CNN, CNBC, NECN, WGBH and the PBS NewsHour.
