In Flex: The Art and Science of Leadership in a Changing World (2019,) leadership consultant Jeffrey Hull on being a “beta leader”:

Beta is a shift in mind-set from a goal-oriented, top-down figuration to a growth-oriented, process-based one. When we live in beta, we are in flux, always improving, and always aware of the need to disrupt the status quo. Beta means being comfortable in a state of constant growth, not aspiring so much to ascend the hierarchy and dominate from above, but to lead from anywhere, anytime.
