What Day1 Company does

Day1 Company (KOSDAQ: 373160) is a Seoul-based, publicly traded education technology company founded in 2013, operating primarily through its FastCampus brand. The company runs an adult-focused online professional education and career training platform that serves Korean working professionals and career changers seeking AI upskilling, with curriculum covering advanced topics such as Deep Research, Reasoning, and Agent-based automation. FastCampus is positioned to address Korea's structural AI talent gap through demand-driven job analyses, scholarships, and direct pathways from training to internships and employment with Korean employers seeking job-ready AI specialists.

The platform is content- and partnership-led rather than technology-build-led. Its core offering integrates OpenAI's advanced models via the OpenAI Edu program — making FastCampus the first private Korean enterprise and only the second institution nationally (after Seoul National University) to do so — supplemented by a January 2026 MOU with AI infrastructure provider Upstage, which contributes GPU compute, datasets, evaluation systems, and technical mentoring for demand-driven training. Day1 does not develop proprietary frontier AI models; its differentiation lies in curating and operationalizing frontier AI capabilities for workforce deployment. In July 2025 the company extended its surface area by acquiring NOA.

Day1 generates revenue primarily through online professional education programs and course fees (pricing not publicly disclosed), segmented vertically to serve both individual learners and Korean corporate buyers of AI-trained talent. The company has raised approximately $63M in disclosed venture funding across rounds from 2018 to 2023, culminating in its KOSDAQ listing. Revenue has plateaued in the ~82–90B KRW range (~$60–66M USD) over the last three fiscal years, but profitability has inflected sharply: net income moved from losses of ~18.9B KRW in 2021 to net income of ~3.3B KRW in 2025, with FY2025 EBITDA of ~11.4B KRW.
