Founded by Gunwoo Kim & Yong Hee Lee
Hey everyone! Meet Gunwoo and Yong Hee, they first met in 2015 through a student club at KAIST, where they organized an annual international conference for undergraduate students. Since then, they've been talking about starting a company together.
The founders are building Cuckoo to help global teams talk to their customers worldwide. Give it a try in your next global meeting 🌏
Language barriers are a big challenge even for global companies. The Cuckoo founders experienced this firsthand in Korea, where they hosted community meetups, inviting product leaders around the world.
On the one hand, many nuances and details can get lost between languages, especially during technical conversations. On the other hand, speakers often felt isolated, unable to follow Korean discussions, and missed valuable opportunities to network and promote their products.
Take Matt, a Solutions Engineer at PagerDuty APJ, who engages weekly with customers in Korea and Japan. These conversations are complicated not just by language barriers but also by technical details—think complex troubleshooting scenarios.
Cuckoo provides real-time translation tailored for you and your customers. It instantly learns technical details from your documents—pitch decks, meeting notes, API docs—and delivers context-aware translation in 20+ languages.
Invite Cuckoo to your online meeting. For in-person conversations, you can capture audio directly from your laptop.

Upload relevant documents (pitch decks, API docs, user manuals, etc.) to help Cuckoo understand the general context and key terms.
As the conversation unfolds, your and your customer can view live translations in your preferred languages.
The founders—the first customer—use Cuckoo everyday to demo and collect user feedback. Here’s how other teams use Cuckoo.
Cuckoo is also used by enterprises beyond the tech industry, including healthcare (SNOMED), manufacturing (SeAH Steel), and retail (GS).
