Bio

Co-founder & CEO, GTM at Cuckoo, AI interpreter for global teams. Before Cuckoo, I was the first GTM at two startups in Korea—one focused on online programming and the other on AI infrastructure—where I also led event marketing involving international speakers. I studied Electrical Engineering and Science & Technology Policy at KAIST.
