Our story
We build cultures that reduce the cost of failure and increase speed of execution.
We work with organisations where performance matters, pressure is real and the human cost can no longer be ignored.
In 2019, amidst shifting workplace paradigms and growing complexity, Vanessa Belleau - a seasoned brand strategist, executive coach, and former Consultancy EMEA Director at WGSN - set out to redefine how organisations align organisational culture with strategy and creativity.
Her mission was clear: to help leaders and teams focus on what matters by turning challenges into opportunities, silos into synergy, and bold ideas into measurable results.
We help leaders and teams perform well in complex conditions without burnout, blame or breakdown - by strengthening decision-making, leadership confidence and the quality of everyday conversations that drive results.
Our work sits at the intersection of performance, behaviour and human reality, where most organisational challenges actually live.
