Our Mission

Global citizenship through language learning and cultural engagement

Our Vision

Learning without borders

Our Story

Our story began in Hawaii, where the founders noticed something remarkable happening while working at a summer retreat open to students from Korea and the United States. Over the month-long camp, they witnessed students’ foreign language skills and cultural curiosity bloom rapidly and organically as the campers participated in high-interest experiences that required communication and cooperation. This sparked an idea - could this same level of engagement, enthusiasm, and efficacy be replicated in formal learning environments like schools and academies?

With this question in mind, the founders set out to create a program that could leverage the expertise of a multilingual, multinational teacher team to inspire students of all backgrounds to become global citizens. And so, ChatENG began. Thousands of students, multiple continents, and many languages later, we’re still working to make language learning and cross-cultural education accessible around the world.

Our Team

Sam Paik

Co-founder and CEO

After a 25-year career in international finance, Sam co-founded ChatENG Inc., believing that technology can greatly enhance language learning by providing live, contextual access to the target language. He also founded a US non-profit that runs K-6 cultural exchange camps in Hawaii and Seoul, promoting experiential learning. Sam's interest in the intersection of education and technology began while serving on the President’s Advisory Council at Wesleyan University. The Council discussed leveraging technology to widen access to education and enhance teacher-student engagement, which resonated with him. Sam continues to stay connected to finance as an investor and advisor in several early-stage EdTech and AI companies.
