About PYLER

PYLER is a technology company founded in Seoul, South Korea, in 2021 by JaeHo Oh, who currently serves as CEO. The firm specializes in artificial intelligence-driven solutions for the digital advertising market, focusing on brand safety and contextual targeting. PYLER has seen significant investor interest, securing a Series A funding round of KRW 10.5 billion in January 2024 and a subsequent bridge investment of $16.9 million (22 billion KRW) in July 2024, bringing its total funding to over $26 million. Key investors include Stonebridge Ventures, Korea Development Bank, SV Investment, and KT Investment. The company's flagship product is 'AiD,' a solution that utilizes proprietary video understanding AI to analyze the context of online videos, particularly on platforms like YouTube. This technology helps advertisers prevent their ads from appearing alongside harmful or inappropriate content, such as hate speech, fake news, and adult material. By automatically scanning and categorizing vast amounts of video content in real-time, AiD provides advertisers with greater control over ad placements, a task that is unfeasible to perform manually given that hundreds of hours of video are uploaded every minute. The system uses a multimodal model that integrates video, image, and text data to ensure advertisements are placed in suitable environments. PYLER operates on a B2B SaaS model, serving global brands and advertising agencies. Its client roster includes prominent names like Samsung, Hyundai Motor Company, LG, and Kenvue. The firm's technology has received academic and industry recognition; it secured 2nd place at the CVPR (Conference on Computer Vision and Pattern Recognition) 2022 workshop and had a paper on its video search technology published at the same prestigious conference in 2023. In 2025, CEO Jaeho Oh was named to the Forbes 30 Under 30 Asia list for his work in the marketing and advertising sector.
