CSOFT International

CSOFT International is a private localization and translation services company that provides multilingual communications, software localization, regulatory translation, and medical/life sciences language services. The company serves a broad range of industries, with a notable healthcare and life sciences offering through its CSOFT Health Sciences business, which has been rebranded as Sesen. Its life sciences work includes support for clinical trial materials, regulatory submissions, medical device documentation, pharmacovigilance content, and global product launch communications. CSOFT emphasizes technology-enabled workflows, proprietary tools, and a large global network of linguists and subject-matter experts rather than developing therapeutic products of its own. For a biotech analyst, the company is best understood as a commercial services vendor to pharma, biotech, CRO, medical device, and healthcare organizations, not a drug developer.
