Lookery

Image via CrunchBaseLookery is an advertising and user-targeting network offering lightweight, economical targeting data.

Lookery is building behavioral targeting systems, without the expensive computation infrastructure or pricey agency sales force. The data-aggregation operations are cloud-based, variable-costed and can be scaled up or down on-demand.

Lookery is taking the cheap, web-scale, participatory tack necessary to provide economical web-wide user targeting: it operates a social network-centric ad network to drive volume, free data collection and large distribution partnerships. Lookery is aggregating user-reported data from, and with the permission of, social networks, dating sites, ISPs, and e-commerce sites. It offers the aggregated targeting data back out via its ad network customers, statistics widgets, as well as unbundled targeting, APIs.

Lookery provides revenue to social networks, dating sites, ISPs, and e-commerce sites by aggregating their user profiles for targeting across the web. When Lookery is paid for user targeting, it shares revenue with the profile contributors. These payments provide a new, and purely incremental revenue stream, completely detached from their site’s page inventory.

Netlog

Netlog (formerly known as Facebox) is a social networking website specifically targeted at the European youth.
Netlog's success is partly due to the localisation which it implemented early in its development.

The site was founded in 2004 in Ghent, Belgium, by Lorenz Bogaert and Toon Coppens, and as of mid-2008 had 37 million registered users across 19 languages.

On Netlog, members can create their own web page, extend their social network, publish their music playlists, share videos, post blogs and join groups. Each member can invite friends on his page and thus create a link between his profile and the profile friends. The world record for the number of friends gathered on a single profile is owned by a Belgian: Ma_planete, who as of July 2008 had almost 12000 people on their friends list.
