Crunchbase is a crowdsourced platform, meaning that profiles on Crunchbase are not affiliated with any one user account and that registered community members can make contributions or edits to almost any profile.
In an effort to verify a user’s true identity and maintain the quality of the Crunchbase platform, we require members to authenticate with LinkedIn, Facebook, or Twitter if they would like to make changes to the Crunchbase dataset.
To add or remove any of your social authentications, click on your account in the upper right-hand corner, then select Account Settings. Here, under Account Information, click on the box that says Social Authentication. A box regarding all your social authentication options (Facebook, LinkedIn, Twitter) will appear.
To turn a specific social authentication on, slide the button associated with that social platform to the right and enter in your login information for that social platform. Once your login has been authenticated, you will see the icon lit up as green. To turn off social authentication for any social platform, slide the button for that specific social platform to the left. Once you have finished setting your social authentications, click the Done button.
