"Once you go from 10 people to 100, you already don't know who everyone is. So at that stage you might as well keep growing, to get the advantages of scale"

In this quote, Sergey Brin, co-founder of Google, is highlighting the principle of scale and its effect on a growing business. He recommends that as a company expands from 10 people to 100, it becomes hard to preserve personal relationships with everybody. At this point, Brin thinks that it is more useful to continue growing in order to gain the advantages of scale. These benefits may consist of increased performance, expense savings, and access to a bigger pool of resources. Brin's point of view stresses the importance of tactical growth and the potential benefits it can bring to a business.
