Andrew Conru, owner of profitable sex site, sits in leafy, relaxed Palo Alto.

Yet few people know how well his company is doing. There’s a notable story in the Mercury News today. is just one of 40 sites run by Conru under the holding company, Various, which is raking in “hundreds of millions of dollars” in annual revenues.

Yet venture investors have shied away from him, in part because of “sin clauses” in their contracts prohibiting investing in adult companies, according to the Merc, which suggests this is a problem.

However, we’re left with some questions. We’re not sure why Conru needs the cash if the company is profitable and raking in so much revenue. The article also says Adultfriendfinder alone is the 58th most popular site on the web, just behind Facebook, but it cites Alexa web-measurement data. Alexa data is notoriously unreliable — especially when it is used to compare something against Facebook . Alexa can be seriously gamed, because it relies on software downloaded by relatively small number of people to track traffic patterns.

Or perhaps there no one else willing to track this area? ;)
