Mundo AI

Mundo AI (YC W25) builds high-quality multilingual training data for AI models, tackling the shortage of non-English data that leaves most of the world's languages underserved by today's models. The company partners with native speakers and runs end-to-end operations in the countries where target languages are spoken, using proprietary software for data collection, generation, annotation, and quality assurance. Founded in 2024 by four University of British Columbia alumni, its customers are AI labs and companies training or improving non-English and multimodal models.
