The purpose of the site is to allow registered users to maintain a list of contact details of people they know and trust in business. The people in the list are called Connections. Users can invite anyone (whether a site user or not) to become a connection.

This list of connections can then be used in a number of ways:

• A contact network is built up consisting of their direct connections, the connections of each of their connections (termed second-degree connections) and also the connections of second-degree connections (termed third-degree connections). This can be used to gain an introduction to someone a person wishes to know through a mutual, trusted contact.
• It can then be used to find jobs, people and business opportunities recommended by someone in one's contact network.
• Employers can list jobs and search for potential candidates.
• Job seekers can review the profile of hiring managers and discover which of their existing contacts can introduce them.
