The evolving culture challenge in fast-growth businesses is a critical factor influencing their ability to scale. A year-long pandemic has tested company cultures to the max, and different roles play various factors that make up a culture, including hiring and retaining the right people, aligning goals, and displaying complementary behaviors and mindsets. As a non-founder CEO of a fast-growth technology business, I've seen firsthand how important it is to identify and safeguard unique cultural elements that have made the company successful in its first stage. However, slow changes can lead to a comfort zone mentality, where true fast-growth companies must break down walls and empower teams with a no-limits innovation mindset. To achieve this, leaders should make change about opportunity, not uncertainty, communicate clearly, empower teams without sacrificing accountability, recognize the value of recognition, and keep the flame alive by refiring up entrepreneurial passion and ambition. By doing so, fast-growth businesses can thrive in uncharted waters and continuously evaluate and intervene to stay on course.
