Sebastian Cwilich

Sebastian Cwilich is the founder and CEO of Tertulia, a book-discovery company that uses machine learning to surface the books people are actually talking about online. An Argentine-born physicist who spent years at AT&T Labs before reinventing himself in the art market, he co-founded Artsy and built it into the world's largest online fine-art marketplace as its president and COO. With Tertulia he set out to do for books what Artsy did for art: turn scattered conversation into discovery. The company launched in 2022 with $6M in seed funding led by AlleyCorp and, by 2025, pivoted toward author services with a popular automated website builder.
