zivity.jpgZivity, the start-up featuring semi and fully nude women in different poses, has a simple model: Make a social network similar to Facebook or MySpace, but with two separate user bases — one being subscription-paying members, and the other being models and photographers who post (artistically) nude photo-sets on the site.

Zivity has proven itself something of an anomaly by raising $8 million to date from some well known venture firms. The first million came last year, and $7 million was just added on by Bluerun Ventures and Founders Fund.

Investors normally shy away from anything that might be labeled porn, mainly because everyone else in the world also shies away from it. Advertisers, especially, tend to avoid even slightly controversial sites. Hence the subscription model, which is pretty much standard for the industry. With this investment, San Francisco’s Founders Fund continues to assert its maverick status among firms.

Malloy, who previously backed more IT-focused companies like Riya, Slide and Varoli, was quoted as saying: “Zivity, much like Slide and PayPal before it, has a driven and talented team focused on challenging the status quo and creating a large new market opportunity.” Founders Fund Luke Nosek also joins the company’s board.

Aside from the nudity, Zivity is keen on selling itself as a social network, not as a porn site. When I talked to him, co-founder Scott Banister — who previously co-founded the decidedly non-sexy Ironport Systems and helped sell it for $830 million last year — repeatedly referred to MySpace’s policy of removing any sort of nudity from its site.

“If the MySpace anti-nudity team took a month off, they’d come back and there would be nudity everywhere. In the world we live in now, people want to be famous, they want to be creative,” he said. He’s hoping they want money, too — Zivity will share 40 percent of all its revenue with the models and photographers who post up sets, based on votes given out by members.

The site will also feature blogging and videos. There’s no requirement for nudity, but it’s obviously going to be the big selling point for members to shell out $10 a month.

I agree with Banister that there’s no point in being a prude. If nudity makes for a good business model, then go for it. On the other hand, the Internet is filled with porn. It’s not hard to be skeptical about Zivity. Why would attractive women spread around nude (or even half-clothed) photos of themselves on a social network with several hundred thousand or even over a million members — and where will all those paying members come from in the first place?

There’s a bit of a chicken-and-egg problem. Unlike a site like SuicideGirls (which Banister says is just a niche site), that pays both models and photographers up-front, models will have to wait for money to accumulate from paying members. On the other hand, members won’t start paying unless there’s plenty of content.

And there is still social stigma attached to being a member of a site like Zivity, even if it looks more like Web 2.0 than Penthouse. It’s worth noting that PlayBoy has dealt with some of the same respectability issues. For more on that, read a recent interview on Freakonomics with its editorial director, Chris Napolitano.

Zivity will begin charging its 1,000+ beta members within the next three months, so we’ll soon see whether it can work. Banister says there are about 75 models with sets up on the site so far (and from a quick glance, some of them are pretty good-looking). The company, which is based in San Francisco, will remain in an invitation-only beta until early 2009.
