Combining information from the existing LinkedIn network, the profiles also display company information, key industry statistics and targeted job listings.
At launch, key partners have included recruitment advertising on their company profiles.
Over the next few phases of this initiative, LinkedIn plans to enable all companies to add customised sections such as ‘Employment Benefits', ‘New Products' and other company information.
Data on company profiles is based on information from the existing 20 million-plus professional profiles on LinkedIn and as well as data from its partners, CapitalIQ and BusinessWeek.
"Not only will company profiles enable people to leverage intelligence from their LinkedIn network to learn more about companies, they will also serve as a vehicle for the companies to reach potential employees, customers, journalists, and partners," said David Hahn, director of product management at LinkedIn.
Some non-professional networks, including MySpace and Facebook, already allow companies to create a presence on their sites via branded profile pages and applications.
