Two companies

In company where I work, director ask me to implement suiteCRM, for bouth companies (company X and company Y).
Is it posibble to create in one suitecrm bouth companies (they have separate customers, employees…) or i have to implement two suitecrm ?

The easiest way is to implement two CRM’s. SuiteCRM doesn’t currently support a multi-tenancy set up without customisations.
