Given Google's capacity for freezing organizations and individuals (even those who are paying customers of its products) from Google services out of the blue and with little to no recourse, I'd most recommend that you secure your startup best by simply not even using google for key parts of its operations if at all possible.
And all the downvotes! From the same site in which so many other people complain about so many ways in which Google hurt them or their business in some way. Absurd.
