Django form with fields from two different models

I need to display one form with several fields from two different models. The form will contain only part of the fields from the models, and the layout will be made using crispy forms.

My models:

class Company(BaseModel):
    title = models.CharField(_('Company'), max_length=128)
    domain = models.CharField(_('Domain'), max_length=128)
class Account(BaseModel):
    company = models.ForeignKey(Company)
    user = models.OneToOneField(User)
    role = models.CharField(_('Role'), choices=ROLES, default='member', max_length=32)

Fields that I want to display in the form: company name, username, user name, user email address

Is it possible? How can i do this?
