Last week, Matter’s third round of start-ups demoed their products in New York City. Two were particularly interesting for journos and publishing outlets. First, there’s Stringr, a platform for licensing freelance video content. News organizations can put out a call for content, what kind of shots they need, of what, how long, all of that good stuff. If it’s breaking news, videographers with the app can run out and shoot it. The goal, according to CEO and co-founder Lindsay Stewart, is not only to get the news org the content within an hour, but also pay the freelancer right away.
