The promising Korean startup’s selection for "U-KNOCK in USA" signals a new, data-driven era for understanding audience engagement in Hollywood.
SEOUL, South Korea, Oct. 16, 2025 /PRNewswire/ — HiStranger, a leading Korean Emotion AI startup, today announced its official U.S. market entry following its selection for the prestigious "U-KNOCK in USA" program. The company is set to introduce Insight Flow, a groundbreaking solution designed to replace creative guesswork with objective emotional data, poised to revolutionize how Hollywood content is developed, tested, and perfected.
Operated by the Korea Creative Content Agency (KOCCA), U-KNOCK is an exclusive program that bridges Korea’s most innovative companies with the U.S. entertainment market. This year’s event features keynote speeches from K-Content titans like CJ ENM and SM Studio. HiStranger was selected as one of only 10 promising startups chosen to participate, highlighting its role as a key player in the next wave of content technology.
Through the program, HiStranger will engage in high-level events, including the International Content Investment Forum and 1:1 Business Meetings with U.S. investors and studios, focusing on co-development and investment opportunities.
"For too long, multimillion-dollar creative decisions have relied on instinct alone. We are here to change that," said D.K. Kim, CEO of HiStranger. "Being selected for U-KNOCK gives us a platform to show Hollywood how data can empower creativity, not hinder it. We are offering a new way to understand audiences on a fundamental, emotional level, which is the key to creating truly resonant content."
HiStranger’s flagship solution, Insight Flow, tackles the industry’s most pressing challenge: predicting audience connection. The platform uses a combination of biosignals—including heart rate (PPG), brainwave activity (EEG), and Facial Expression Recognition (FER)—to measure and analyze viewers’ real-time, authentic emotional responses.
The platform’s data-driven dashboard allows studios and creators to pinpoint exact moments of high engagement, confusion, or emotional disconnect. This provides a scientific layer of insight to the creative process, enabling more informed decisions that de-risk investments and maximize audience impact.
