Sebastien Deguy

Sebastien Deguy is the founder of Allegorithmic, the company behind the Substance 3D texturing suite that became an industry standard across games, film, and design. After Adobe acquired Allegorithmic in 2019 he served as VP of 3D & Immersive, won a Sci-Tech Academy Award (2023) and an Emmy (2024), then left in 2025 to build content instead of tools. He now runs Sans Strings Studio in San Francisco, a digital-puppetry company chasing 'animation with a soul' through a real-time performance pipeline. He is also an electronic musician under the alias Matterflow and the author of a book on Allegorithmic's history.
