SF-based Zivity, an ‘adult’ social networking site, has raised a $7 million second round from BlueRun Ventures and the Founders Fund. This follows a $1 million raise last November, bringing the company’s total haul to $8 million. The subscription-based site is dedicated to, in its description, “promoting female beauty and expression through professional-quality photography”, and it aims to connect both models and photographers. Basically, female members sign up and post pictures of themselves, while others pay a subscription fee, some of which gets distributed to those who have posted photos of themselves. The payout is determined by user voting. The concept is similar to the site Suicide Girls, which preceded it by several years. The site was co-founded by Scott Banister, who founded IronPort Systems, which was sold to Cisco (NSDQ: CSCO). Release.
