About ZeroXFlow

ZeroXFlow is an ed-tech company that operates '1hour.ai,' an all-in-one AI courseware platform for foreign language education. The company was founded in 2017 by CEO Kim Hong-hyeon, who drew upon 15 years of experience as an English teacher and academy head to address the burdensome nature of class preparation. He initially created a program to help with vocabulary study at his own academy, and based on student feedback, progressively added features like text-to-speech and sentence learning, which evolved into the 1hour platform.

The platform, which supports languages including English, Korean, Japanese, and Chinese, is designed to reduce teachers' workloads and enhance educational efficiency for both public and private institutions. Its core service, the '1hour' platform, signifies the goal of reducing hour-long lecture preparations to just one minute. 1hour provides a suite of management systems: a Teaching Management System (TMS) for effective on- and off-line instruction, a Learning Management System (LMS) that digitizes offline materials into over 20 learning chains, a Data Management System (DMS) for analyzing and sharing student progress, and a Content Management System (CMS) that can absorb various materials like videos, books, and PDFs. The platform features AI-driven tools such as 'Quiz AI,' which can generate 1,000 test questions from a text in 10 minutes, and 'Writing AI,' which automatically grades and provides detailed feedback on student essays. It serves clients in the education market, enabling them to create lesson materials from diverse content like YouTube videos, PDFs, and audio files.

ZeroXFlow has achieved significant milestones, including winning the D.camp D.Day competition in 2020. The company secured a KRW 3.5 billion Series A investment in November 2023, led by Hana Ventures with participation from existing shareholders Aceton Ventures, Laguna Investment, and Must Ventures. By late 2023, the platform was being used by over 24,000 students across more than 750 educational institutions.
