As a non-hierarchical cell-based organization, cells operate independently to allow swifter decision-making without traditional hierarchical delays. This approach encourages innovation, as each cell is closer to the issues it addresses and can respond rapidly to any changes. It also creates a culture of accountability and ownership, as individual colleagues feel directly responsible for the success of both their cell and the company. The Leadership Team steers the company’s growth and strategy and ensures all legal and governance responsibilities are met.
