The company delivers translation, localization, and AI-enabled multilingual content services to a base of 2,000+ enterprise clients across technology, cybersecurity, life sciences, e-commerce, social media, financial technology, and biotechnology. The company operates a multi-brand structure under the parent Welo Global, comprising Welocalize core, Park IP (legal and intellectual property), Welo Life Sciences (clinical, regulatory, and medical device localization), Adapt Worldwide (marketing localization and transcreation), and Welo Data (AI training data services for model developers).
