What CSOFT International, Ltd. does

CSOFT International, Ltd. is a privately held professional translation and localization services provider founded in 2003 and headquartered in Boston, Massachusetts, with operational presence in Beijing, China. The company serves enterprise clients across 12 industry verticals including life sciences/pharmaceuticals (via its Sesen sub-brand), IT and software, manufacturing, legal, financial services, and energy, delivering services in 250+ languages through a curated network of 10,000+ in-country linguists and subject matter experts. Its core service portfolio spans medical/regulatory documentation translation, software and website localization, technical translation, video/voiceover localization, interpretation, and enterprise language management, supported by proprietary technology including the UbrTa translation management system, the GMS Cloud / Stepes cloud translation platform, TermWiki Pro for terminology management, and XLIFF-based localization workflows with integrations into Articulate, SCORM-compliant LMS platforms, and other eLearning ecosystems.

The company's business model is enterprise services-led, with revenue generated primarily through professional services engagements (translation and localization work billed per project, word count, or scope) and some recurring retainer-style engagements for enterprise language management. Pricing is quote-based rather than publicly disclosed, with client acquisition driven by direct field sales, RFP/RFQ/tender processes, and thought-leadership content marketing through its blog, white papers, webinars, and multilingual SEO-optimized websites. The company is differentiated by ISO 17100, ISO 9001, and ISO 13485 certifications, a 24/7/365 global delivery model, and 17+ years of organic-only growth. It maintains no public funding history, has no disclosed revenue, and shows no recent M&A activity; its principal corporate transformation in recent years has been the 2023 rebrand of CSOFT Health Sciences into the standalone Sesen brand focused on life sciences translation.
