Companies that successfully build brands are those that create communities around their products. The strength of these communities builds loyalty and connections among customers, increasing their likelihood to stay and remain engaged. This concept applies to physical communities as well. By fostering strong bonds, companies can achieve higher retention rates and lower churn. This principle is similar to Metcalf's Law, where the more nodes in a network, the stronger the network becomes. Tight-knit communities, whether in ethnic or religious groups, thrive because of the close connections and knowledge of each other's strengths and needs. This concept is applicable to various fields, including technology and design communities. The more tightly-knit tribes are, the greater their chances of survival and success.
