ABOUT ME

Thomas Cottiaux
Building digital product that matters.

My path hasn't been typical. I started as a data engineer helping companies measure their environmental impact through ESG analytics. I built dashboards, ML models, and data infrastructure that powered sustainability at scale. But something was missing.My experience working directly with local social organizations still echoed as the most driven I've ever been. I decided I needed to be close to the people creating change. So I spent years facilitating innovation workshops, led social innovation programs, mentored founders, and learned that for tech to be impactful, it didn't need to be complex—it needed to be centered around people. Today, I combine both worlds. I help creative entrepreneurs, social ventures, and mission-driven organizations turn ambitious ideas into digital realities. Whether it's prototyping an MVP, building data infrastructure that actually helps make decisions, or facilitating design sprints to craft user experiences. I bring technical experience and creative empathy to every project. I've been pursuing photography and music all my life, and I make them an inherent part of my process, bringing stories and aesthetics to the work.If you believe in your project and want to bring it to the next level, let's talk
