Corporate maturity is a valuable concept in that it provides a holistic view of an organization's performance, sustainability, and resilience. We present a general model of corporate maturity, which is applicable to any sector, with four main stages of development. We demonstrate how an organization can enhance its maturity through a focus on ethics, good governance, and community outcomes. We find that more mature organizations are those that find connections between corporate purpose and wider social and human needs. The authentic company, much in demand by investors, consumers, regulators, and employees is one that can be trusted to deliver these needs as result of deeply embedded integrity, uncompromising unconditionality and outcomes rooted in the community.
