Our Story

Yellowverse: Caring, Optimistic, Knowledgeable



Tree Yellow was founded in Dubai 2016 on the belief that people want to lead meaningful and fulfilling lives and to cultivate what is best within themselves. When individuals and teams gain insights, create meaningful connection and seek relevance through their work they develop a strong sense of identity, lead with confidence, and create meaningful change.

This belief led to the creation of Yellowverse—a dynamic learning ecosystem where experiential learning, coaching, leadership development, and neuroscience come together to shape transformational inner skills for sustainable performance. In this ecosystem we ensure that learning is a continuous process where people apply what they learn, develop critical sense making capabilities, and grow personally and into roles that drive their teams and businesses forward.

At Tree Yellow, we work with you to shape self-aware leaders who think strategically, teams that build high trust and respect, and workplaces cultures that support a sustainable performance ethos. By making learning engaging, practical, and relevant, we help you ensure that individuals and organisations are prepared to meet the complex challenges of lasting change for a more equitable, thriving world.
