Founder & CEO — LinguaX AI

Building the AI that makes humans fluent —
not just grammatically correct.

Who's Emanuel?

I'm a US-incorporated founder building from Madrid. My company, LinguaX AI, builds the autonomous AI voice trainer engineered to achieve real-world spoken fluency — not just grammar rules. It bypasses the cost and friction of human coaching, tapping into a multi-billion dollar market with a high-margin, instantly scalable software solution.

🇺🇸 English 🇰🇷 Korean 🇨🇴 Spanish

Born in Bucaramanga, Colombia, I've lived and built across Mexico, Panama, Colombia, and now Spain. I'm obsessed with languages and technology — and convinced that AI will fundamentally change how humans learn to communicate across cultures.
