Dongjin Lee is the Founder and CEO of 2-b.ai, an AI-powered productivity platform based in Seoul, South Korea, built to help users get more done directly from any webpage.

Dongjin is connected to the Korea Trade Association Soft Engineer Society, reflecting a foundation in software engineering and a passion for practical technology solutions.

Dongjin was driven to build 2-b.ai after recognizing how difficult it still was to use AI meaningfully in daily work, turning that personal frustration into a breakthrough product vision.

At 2-b.ai, Dongjin has led the development of a browser-native AI tool that lets users highlight text for instant task breakdowns, draft content, and execute research without leaving any webpage.

2-b.ai has grown to attract a wave of new users, offering keyboard-shortcut access (Cmd+J / Alt+J) on any webpage and positioning itself at the forefront of Seoul's rapidly expanding AI productivity startup ecosystem.
