If you have investors in your network, you can invite them to view your profile as well. Under the "Campaign" tab towards the top of your Fundable page, there is a separate sub-tab that says "Investors."
Within the "Investor" tab, there should be a button titled "+Invite an Investor" and you can manually invite specific people to view the profile and automatically grant them full access.
Just complete the information needed and click the send invitation button. The investor will receive the invite with a link to your profile.
