Founder
Swanstant is led by François Souchet, who built the firm to apply quantitative climate-economic research to the operational and financial decisions where climate impact is most material and most consistently underpriced.
Trained as an engineer (classes préparatoires at Lycée Stanislas, civil engineering master's at ESTP, master's in engineering management at the University of Melbourne), François began his career at Accenture in operations and supply chain, advising industrial clients globally on productivity, cost, and operational resilience. He subsequently led Make Fashion Circular at the Ellen MacArthur Foundation (2018–2021), a research institution producing macroeconomic and sector-level analysis on circular systems, where he developed quantitative models of the macroeconomic opportunity of the circular transition and built operational frameworks adopted at scale.
His applied work at Swanstant spans industrial and institutional clients on quantitative climate-economic analysis across commodity markets, heavy industry, and consumer-facing sectors. He is a member of the SMEP Independent Technical Advisory Panel.
The firm's methodology is reviewed by an advisory committee of climate-economic specialists.
