To add a contact to an investor in your fundraising pipeline, you will want to open Visible and the pipeline where you'd like to add the contact. Open the investor record where you'd like to add the contact. Type their email under Contacts and click enter.
Once added you can view and edit any of the custom or default contact properties directly on the investor record.
