Sopht is a French IT efficiency platform that measures the costs and carbon footprint of a company's whole IT estate (cloud, data centres, devices, applications and AI) and turns them into ranked actions that cut both.
About Sopht
Sopht was founded by three former consultants, Jérémie Veg, Julien Rouzé and Gautier Levert, and launched its platform in 2022 with one mission: make IT efficiency measurable. The French company works with large organisations such as BNP Paribas, VINCI, Adecco, LVMH, Airbus and the CNAF, and tracks 67.1 kt CO₂e of annual IT emissions on its platform. Sopht puts the potential return at 4 euros saved for every euro invested, and about 1 tCO₂e avoided for every 10 euros invested. Station F named it a Future 40 laureate in 2023, the year it became a mission-driven company (entreprise à mission). Sopht launched in the United Kingdom in 2025, then raised a €7.5M Series A and signed a global partnership with Infosys in 2026.

Cutting the carbon footprint of the cloud by a third
Younited, a European instant-credit and online-financing company, had to absorb fast growth in cloud usage while keeping costs and emissions under control. The team cut storage in development and test environments (shorter log retention), pooled services such as Redis that each team used to run on its own, moved towards containerised architectures on managed services, and set up daily tracking of cloud usage with alerts on unusual drift. At constant scope, the production cloud bill fell by about 10%, the overall cloud bill by 7% and the carbon footprint by about 33%.
“Before Sopht, we had no reliable measurement or traceability of our digital footprint. It was difficult to quantify emissions related to servers, the cloud, networks, and workstations, and to clearly distinguish the different sources of impact.”
Jean-Paul Verneret,IT Leadership support, CNAF
“At Adecco, we knew that the environmental impact of digital would become a strategic issue, not just to meet regulatory requirements, but to reflect our values. Sopht helped us structure our Green IT approach, automate data collection, and turn an initial intention into a concrete, measurable action plan.”
Julien Choubrac,Workplace Manager & Green IT Lead, Adecco
“Measuring and understanding our primary emission factors is undoubtedly a challenge in itself, but piloting them dynamically with concrete action plans is what the Sopht platform enables us to do.”
Marie Ait Daoud,Green IT Manager, VINCI
“From the very inception of our assets, we are committed to minimising the environmental impact of our information systems. Through a strategic partnership with Sopht, we have implemented a solution to quantify the carbon footprint of our applications, thus aligning with the group's 2025 strategic plan.”
Françoise Orand,Green IT program manager, BNP Paribas
