With Crunchbase, any registered user (with a social network connected) can add or edit profile pages. If you don’t have a user account yet, you can register for a user account here.
Once you've logged in and authenticated via a social network, you can visit your existing profile by finding it through the top search bar.
To edit the profile, click Edit at the top right of the profile page.
*Note: You do not need to have a Crunchbase Pro subscription to edit profiles.
