Everyone named here works with us as an external partner, not as an employee of 99rabbits.

Why 99rabbits

A rabbit and an order.

The name brings two things together: the rabbit as a symbol of transformation and change, and "order 99" from the Star Wars universe, the call to do good in the world.

Together they describe what drives us: shaping change that has an effect. For people and for organisations.
