Our story
Transforming workplaces, one conversation at a time
High Fifteen was founded with a bold vision: to create high performing workplaces that feel deeply human.
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.
High Fifteen’s journey is rooted in a commitment to true inclusion mixed with high performance and the belief that collaboration is the foundation of extraordinary workplace cultures.
Today, we partner with organisations worldwide, delivering tailored strategies and training solutions that unlock potential, improve retention, and drive transformative growth.
