Twist Bioscience develops a proprietary DNA synthesis platform that miniaturizes chemical reactions on silicon chips, enabling the rapid and cost-effective production of synthetic genes, oligonucleotides, and DNA libraries for research and therapeutic applications. The company serves over 3,800 customers globally across three segments: synthetic biology products (including genes and oligo pools), next-generation sequencing tools for diagnostics, and biopharma services including antibody discovery. Revenue derives from direct product sales through e-commerce and sales teams, service fees for antibody discovery programs, and licensing and milestone payments from partnerships with biotech, pharmaceutical, diagnostic, and academic customers.
