Our Team

The three Cobalt co-founders all have startup exit experiences and have a long history of working together. The CEO, Haei Yi, and COO, Stella Kim, were co-founders of Dunamu, which is running Upbit. The CTO, Sunhyeop Lee, joined the squad when Haeil and Stella worked for a company making AI-speaker for kids and have still been working together. We are always interested in new and effective communication.

We think that sales are the most essential communication for the economic life, but sales sucks. We want to make sales intersting and easy with a good communication tool for both sellers and buyers.
