Meet our team

At MLG International, we believe that artificial intelligence should be just as intelligent in Spanish, Hindi, Arabic, or Swahili as it is in English. Our team is driven by the idea that language should never be a barrier to innovation. Today, the vast majority of AI systems are trained primarily on English-language data, leaving a gap that limits global access, accuracy, and cultural relevance.

Our mission is to close that gap. We work with expert linguists, cultural specialists, and AI developers to help companies build multilingual models that don’t just translate but truly understand. By enabling AI to speak the language of each market, not just linguistically but contextually), we help businesses reach more people, more authentically, and more effectively.
