MAIN SKILLS

Social Impact

My first job was with a major consulting company in Japan. I appreciated my time there, but was always yearning to do something with a greater direct impact, and something that gives me a greater sense of purpose. I am blessed to have the opportunity to travel the world, and be exposed to different perspectives, ways of living and available alternatives!

A series of serendipitous events led to the founding of merchandise.blue with two highly experienced and interesting friends. Merchandise.blue offered merchandise like uniforms, towels and bags in more environmentally progressive textiles made of materials like seaweed, organic cotton and recycled fishing nets. 

When the opportunity to open Kizuna arose, it was clear that I wanted to apply similar values and principles to this physical space.

Sylvain Mahe
Head of Sustainability - Palo IT
MAIN SKILLS
Change Management
Sustainability Leadership
Green IT

With a foundation in software engineering, I've journeyed through agile coaching to conscious leadership and systems thinking. Now, I guide organizations through complex transformations — agile, sustainability, and AI — by fostering human-centric approaches and systemic understanding. I'm passionate about evolving leadership to navigate our increasingly technological and interconnected world responsibly.

I am absolutely convinced that the solutions to our current global predicaments do not primarily lie in "doing" more or focusing solely on actions. Instead, I believe the answers are found in our "beingness" — our mindsets and underlying belief systems. Addressing our challenges effectively requires a fundamental shift in consciousness. Once that internal shift occurs, the right actions will naturally follow. Simply starting with "doing" or concentrating too much on technical solutions, without this deeper shift, won't lead us to the desired outcomes.

Thibaut Meurgue
CEO – The Transmutation Principle
MAIN SKILLS
ESG Coaching
Climate Adaptation and Resilience
Sustainable IT

I am Thibaut, French bald since 26 & bold since forever! Right now, I am the CEO of The Transmutation Principle. 

I come from an IT & software agency background, so deeply into B2B and old-fashioned processes. I came to realize that sustainability cannot be only about consumers and half-hearted measures. I also realized IT sustainability was highly underrated and not understood by most companies. It came as quite a surprise for me, since I always considered IT sustainability to be one of the best ways to merge both ROI & sustainability to make the latter sound acceptable, actionable, and realistic. Having seen that, I wanted to make a change in my own way. 

My dedication came from the desire to be able to look my future kids in the eye and tell them that I tried to make the world a better place. 

I co-founded The Transmutation Principle, a Singapore-based consultancy, to support businesses in their quest for impact through actionable and tailor-made sustainability & ESG programs.
