FORTUNE -- Stephanie Horbaczewski, a fur shawl draped over her shoulders and a Celine tote propped at her feet, radiates chic. But the former Saks marketing executive is much more than an impeccable fashionista: in less than two years, Horbaczewski's startupStyleHaul has fused lifestyle content andvideo into a potentially lucrative network.

StyleHaul's videos are crisp, cleanly packaged, well-produced and, most notably, created by outsiders. Horbaczewski, 34, and her team manage a community of 1,100 channels, run by 800 video bloggers -- or vloggers. The fashion startup closed its Series A in January, raising $4.4 million with RezVen Partners taking the lead. The company has doubled in size over the past nine months and now serves an audience of 41 million unique viewers a month. It could bring in between $10 million and $15 million in revenue by the end of this year, according to a person with knowledge of the business.
