To update the image on your Crunchbase account, click on the Account icon in the upper right corner of any page, then select Account Settings.
Under the Your Info tab on the left hand side, you'll see the option to upload or change your profile photo in the Personal Information section.
Keep in mind, updating your image in your account will not change the image on your profile. A user account is the private information used to control your login information, billing, and alerts. Your profile page is what displays externally on Crunchbase. To learn more about this, click here!
