CO is, in essence, a matching engine. When you join, the site asks you to enter information about yourself, your skills and what you are looking for, so that it can match you with relevant information, people, and organisations that can help you to achieve your goals. Members join as individuals first, then have the opportunity to set up one or more business profiles.
Business profiles are weighted on CO. If your business is operating to high ethical, sustainability, and quality standards, you will come up higher in searches, and therefore your business will gain more profile on the site.
You can join CO, set up individual and business profiles, and start to get matches, completely free of charge. You will then have the opportunity to upgrade to premium membership, which will allow you to access more content, do more with your profile, and make more connections.
