The all-in-one solution for learning professional English. Slang's platform features the largest offering of professional English courses in the world, with more than 200 courses in highly specialized areas — from Manufacturing to Psychology — and in the next three years we’ll have more than 1,000. Our extensive library allows companies and universities to bring their teams beyond basic English by creating hyper-personalized career paths — right down to the job title or major — regardless of area, industry, or role. Slang started at MIT as a research project where they discovered a highly adaptive learning experience — powered by the latest in ML and NLP — that creates the most efficient path to fluency by focusing only on what learners don’t already know. This innovative experience led Slang to be recognized as the world’s most promising startup of 2020 at the Global Edtech Startup Awards. Headquarters: Boston, MA Offices in: Colombia, Mexico, and Brazil Learn more about our unique approach at slangapp.com. We’d love to field any questions you have about our product and vision!
