Our Mission

Unlocking global potential with professional English.

Everyone deserves access to world-class opportunities for education and professional development, but the vast majority of high-quality learning and development material is encoded in one language: English. Billions of people are being left behind. Slang is closing this knowledge gap with the largest offering of professional English courses anywhere.

Our story

Slang was born at MIT out of the collaboration between two students, Diego and Kamran. Through Diego’s personal experiences — watching the employees of his companies in Latin America and his international classmates at MIT struggle with field-specific English — he realized that there was no English-learning solution on the market that could meet the needs of professionals and businesses, needs that go beyond basic English. Kamran’s expertise in ML and NLP was the missing piece to make this dream a reality. Together, they developed the cutting-edge algorithms that form the backbone of Slang’s adaptive approach.

We’re redefining the market with our specialized offering, enabling organizations to unlock the potential of their workforce.
