Mark Stevenson is a systems change adviser, author and entrepreneur working across climate, innovation and institutional transformation. He co-founded CUR8, a company developing portfolios and infrastructure for carbon removals, and now serves as its ambassador. His current work also includes strategy and special projects with Oath Soil Life, alongside wider advisory and speaking activity.
Stevenson's career moves between research, ventures and public communication. He is the author of An Optimist's Tour of the Future and We Do Things Differently, and co-founded the cultural change practice The Futurenauts. His advisory work has included questions at the intersection of climate, security and long-term policy, while his entrepreneurial activity has placed him inside the practical demands of turning emerging solutions into organisations and markets.
His distinctive perspective is built around systems change rather than prediction. He examines why promising technologies or policies fail when institutions, incentives and culture remain untouched, and uses eight principles of successful optimism to connect possibility with disciplined action. Optimism, in this account, is a method: engage with evidence, seek out people already building alternatives and accept the responsibility to participate.
For leaders, the value lies in seeing transformation as a connected problem. Climate, technology and social legitimacy cannot be managed through isolated initiatives, yet scale can make action feel abstract. Stevenson helps organisations identify leverage points, work across boundaries and distinguish plausible pathways from comforting narratives, while keeping the conversation anchored in what can be built, funded and changed.
