Celest Science

Celest Science develops a climate risk prediction service that leverages proprietary AI models to anticipate extreme weather events and broader climate risks. The company's technical approach combines advanced artificial intelligence with physical models, providing highly accurate sub-seasonal to seasonal predictions and comprehensive physical risk assessments. This innovative system utilizes deep learning and generative models to process complex climate data, enabling a more precise understanding of future environmental conditions.

The company was co-founded in March 2023 by Léo Lemordant, who serves as CEO, and Pierre Gentine, the CTO. Lemordant, a repeat entrepreneur with a PhD in Hydrology from Columbia University, partnered with Gentine, a distinguished Climate and Data Science professor and a PhD from MIT. Their collaboration during Lemordant's doctoral studies provided the foundational insight to apply their specialized knowledge in climate science and machine learning to address critical business needs.

Celest Science primarily serves clients within the insurance, finance, and energy sectors, empowering them to enhance their climate resilience and strategically manage exposure to environmental uncertainties. The company's long-term vision centers on transforming climate event predictions, contributing to a more secure future by enabling businesses to proactively understand and mitigate climate-related challenges.
