They should have left off the "small", and it would have made more sense.
Since I've read that "innocent" book, I'd like to give another perspective. Many entrepreneurs are not willing to get into the consumer goods business because of the giant competitors like P&G, Unilever and Coca Cola. That's why innocent's founders emphasised starting "small" in their book. They started the business in a kitchen and eventually won the battle (sort of) by creativity. That's why stories like innocent and Method are so inspiring.
