LILT was founded by Spence and John, who met at Google working on Google Translate and saw the need for better AI-powered translation in the enterprise. Since 2015, LILT has focused on building cutting-edge language technology, investing early in Large Language Models to improve translation quality and meet the demands of global organizations.

Today, LILT’s Contextual AI Engine, Connector APIs, and Human Adaptive Feedback deliver accurate, nuanced translation across text, video, and speech in 100+ languages. Integrated with 100+ business systems, LILT helps enterprises scale global growth and deliver seamless multilingual experiences. We are trusted by Intel Corporation, Canva, the United States Department of Defense, the United States Air Force, ASICS, and hundreds of global Enterprises.
