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.

Our Culture

We have a flexible, adaptable culture and a relatively flat organizational structure. We focus on being collaborative over hierarchy-oriented, and we believe good ideas can come from any experience level.

Our culture is results-oriented, built on trust and autonomy. Every Slanger is encouraged to cultivate a continuous improvement mindset and find new ways to operate.

We are a people-oriented company: we encourage a healthy work-life balance among our team members and do our best to take care of it.

Diversity at Slang

We’re committed to creating and sustaining a healthy work environment where every team member feels respected, valued, safe, and able to realize their full potential. Every Slanger can create the career path they seek without fear of stereotyping, unequal opportunities, or other forms of discrimination.

Our team is currently lucky enough to include people from Colombia, Mexico, Brazil, the United States, Nigeria, and Rwanda. We’re working to expand the range of cultural backgrounds among our teams and to ensure gender balance within each area as the company grows.
