TechCrunch reports that investment bank Allen & Co. is hoping to help LinkedIn pull in that funding at a $1 billion valuation.
Why $1 billion? Well, LinkedIn says its target demographic has meant that it can pull in some pretty lucrative ad revenue, avoiding the "ad trap" that has hurt monetization efforts on the part of more general-focus social networks. The average user of LinkedIn (there are 20 million total) is reportedly 41 years old and makes about $110,000 annually.
That's made it possible for the social network to charge advertisers $75 per thousand impressions, which is almost unheard of in the social-media world.
Whether that's worth a full billion dollars, well, we'll have to find out.
