Genvid is an award-winning studio delivering a brand new form of entertainment combining the best of traditional storytelling with the immersion and interaction of video games. We call this category Massively Interactive Live Events (MILEs). Imagine you and a global community of fans influencing the canon storyline of your favorite franchises: making choices which will affect the fates of heroes, villains and entire worlds. MILEs also have the unique aspect of giving fans a choice between sitting back and enjoying watching dramatic events unfold, or leaning-in and participating themselves. All of this happens live, in the company of millions of other fans. Genvid’s next exciting project for 2024 is DC Heroes United, an interactive streaming series, licensed by Warner Bros. Interactive Entertainment on behalf of DC, where fans will determine what kinds of DC Super Heroes and Super-Villains our beloved characters will become. Successful past projects include Emmy Award winner SILENT HILL: Ascension (with Konami Digital Entertainment), The Walking Dead: Last Mile (with Skybound Entertainment), PAC-MAN Community (with Bandai Namco Entertainment) and the all-original Rival Peak. All of these projects (and others) are enabled by Genvid’s proprietary and innovative MILEs SDK technology. If you are looking for that rare opportunity to truly innovate digital entertainment, contact us. We’d love to hear from you!

With the goal of rebuilding education through technology, Mathpresso operates its flagship app, QANDA, an AI-powered learning app that allows students of all levels to receive instant answers and customized learning sources. In 2015, Forbe’s 30 under 30 Asia 2020 honoree Ray Lee first came up with the idea of QANDA during his senior year in college. While he was tutoring to earn money, Lee realized that the quality of education a student receives is greatly based on their location. Lee saw his K-12 students were regularly asking similar questions and realized that these questions are from a pre-selected number of textbooks currently being used in schools. He decided to team up with his high school friend, CEO Jake Lee, to build a platform where by way of using a mobile app to scan and submit questions, students can ask and receive detailed responses. In January 2016, Mathpresso’s first product QANDA was launched. It supported a Q&A feature between students and tutors. In 2017, QANDA introduced an OCR-based search capability that permitted users to search for answers in seconds. Powered by AI technology and user data, QANDA shows the best-matched answer in a text, image, or video-based format. Today, QANDA is used by 14m students monthly in over 50 countries and has achieved a top seat position in 20 countries surpassing similar apps. Over 87% of QANDA’s users are now outside of Korea, with its strongest user bases including Vietnam, Indonesia, Thailand, and Japan. QANDA is one of the fastest-growing K-12 mobile learning apps globally, leading the paradigm shift in education. Since its inception, Mathpresso has raised over US$122 million from investors namely Google, SoftBank Ventures Asia, Legend Capital, GGV, and Goodwater Capital. Headquartered in Seoul, South Korea, Mathpresso has offices in Tokyo, Hanoi, and Jakarta.
