Form não cria o objeto no Banco de Dados

Estou tentando fazer com que um form crie o objeto no banco, a função retorna mensagem de sucesso... mas o objeto não é criado.

Função para registrarno banco

@login_required
def register_company(request):
    form = NewCompany()

    if request.method == 'POST':
        form = NewCompany(request.POST)
        if form.is_valid():
            name_company = form.cleaned_data['name_company']
            cnpj_company = form.cleaned_data['cnpj_company']
            area_company = form.cleaned_data['area_company']
            manager_company = form.cleaned_data['manager_company']
            email_company = form.cleaned_data['email_company']
            status = form.cleaned_data['status']
            enterprise = form.cleaned_data['enterprise']
            logo_company = form.cleaned_data['logo_company']

            form = Company(name_company=name_company, cnpj_company=cnpj_company, area_company=area_company,
                           manager_company=manager_company, email_company=email_company, status=status,
                           enterprise=enterprise, logo_company=logo_company)

            form.save()

        messages.success(request, 'Empresa salva com sucesso!')

        return HttpResponseRedirect('list_company')

    else: 
        enterprise = {'enterprise': Enterprise.objects.all()}

        return render(request, 'company/register_company.html', {'enterprise': enterprise, 'form': form})
