Get organization size in Web Personalization

Hi. I have 3 questions about Web Personalization 1) Is it possible to use Web Personalization locally? 2) How to find out the number of organizations in which the visitor works? From the documentation (developers.marketo.com/javascript-api/web-personalization/get-visitor-data/) I cannot get such information. is there any other solution? 3) If the second item can be solved then how for a visitor if he works in an organization where less than 100 employees show one campaign, and if more than 100, then another campaign? Thank you!
