Seoul, South Korea – October 29, 2026 – HISTRANGER, Inc., a deep-tech company developing Emotion Intelligence Infrastructure for artificial intelligence systems, today announced that it will showcase its flagship multimodal emotion analysis solution, Insight Flow, and its proprietary camera-based Pupil-based Mental State Forecasting (PMF) model at Web Summit 2026 in Lisbon, Portugal, targeting paid Proof-of-Concept (PoC) partnerships and technology collaborations across Europe.
A New Paradigm in Emotion Intelligence Infrastructure
Founded in 2022, HISTRANGER was established on the premise that true interaction between humans and artificial intelligence requires machines to perceive and interpret human affective states accurately. While conventional affective computing often relies on isolated visual inputs or generic sentiment analysis, HISTRANGER builds foundational emotion intelligence infrastructure by synchronizing multiple physiological and behavioral data streams along a unified timeline.
The company’s core technological architecture synchronizes electroencephalography (EEG), photoplethysmography (PPG), facial expression recognition (FER), eye gaze, and pupillometry signals. In official evaluations conducted by the Korea Telecommunications Technology Association (TTA / KTCC) in January 2026, HISTRANGER recorded a 94.18% accuracy rate in multimodal emotion recognition. Leveraging this laboratory-grade biosignal data as Ground Truth, the company trains vision models to decode involuntary micro-responses from standard video feeds, making high-precision affective computing scalable for commercial consumer environments.
Core Technologies and Innovations on Display
At Web Summit 2026, HISTRANGER will demonstrate its software solutions designed for digital content optimization, media research, and physical computing:
• Insight Flow: An end-to-end multimodal emotion analysis platform that evaluates consumer engagement, emotional trajectories, and attentional focus in real time while subjects consume video entertainment, interactive games, or digital advertisements.
• Insight Flow Lite: A lightweight, self-service software-as-a-service (SaaS) edition designed to enable global creative agencies, game developers, and research institutions to conduct fast, distributed emotion testing at scale.
• Camera-Based PMF Model: A proprietary computer vision algorithm that tracks involuntary, minute pupillary dynamics to estimate mental attention and arousal states directly through a standard RGB camera, removing the requirement for bulky wearable sensors.
• API and SDK Integration: Developer kits enabling enterprise clients to embed real-time affective computing into AI conversational agents, smart mobility cabin monitoring systems, and human-robot interaction (HRI) platforms.
Demonstrated Commercial Traction and High Repurchase Rate
HISTRANGER achieved operational profitability in 2025 with a 39% year-on-year revenue increase, followed by a 203% revenue surge in the first half of 2026 compared to the same period in the prior year. The company has conducted paid PoCs with 14 enterprise B2B clients across South Korea and international markets, securing a 43% customer repurchase rate.
The commercial viability of Insight Flow was highlighted during the pre-production phase of the feature film Heabi, which completed South Korea’s first script-reading Emotion AI test and leveraged the resulting analytical reports to secure production financing. In another commercial application involving blind audience screenings for a domestic theatrical film, data-driven editorial adjustments guided by Insight Flow contributed to a 17% increase in overall viewer satisfaction scores (rising from 3.18 to 3.72 out of 5.0).
In 2026, HISTRANGER initiated film content valuation PoCs with the Innovation Policy Investment Department of IBK Industrial Bank and Kakao Entertainment, alongside screenplay analysis projects with the Seoul Independent Film Festival. The firm has executed 10 strategic Memorandums of Understanding (MOUs) and 17 Non-Disclosure Agreements (NDAs). Globally, HISTRANGER has been recognized as a selected startup at Berlinale EFM Startups 2025, a global finalist at South Summit Madrid, a finalist at IVS Kyoto LaunchPad 2026, and a two-time participant in the Busan International Film Festival’s ACFM InnoAsia platform.
“Human emotion is complex, yet it leaves distinct physiological footprints that machines can learn to understand with rigorous scientific precision,” said Kim Dong-kook, CEO of HISTRANGER, Inc. “By translating lab-grade biosignals into scalable camera-based computer vision models, HISTRANGER removes the physical friction of wearable sensors while maintaining predictive accuracy. Web Summit 2026 serves as our launchpad to introduce Insight Flow and our PMF technology to European entertainment, gaming, and mobility leaders seeking data-driven audience intelligence.”
European Market Expansion and Strategic Outlook
HISTRANGER currently generates commercial revenue across South Korea, Japan, and Singapore, and is advancing technical discussions with partners in France and Taiwan. Following successful presentations at European industry venues including EFM, VivaTech, South Summit Madrid, and K-EXPO France, the company is using Web Summit 2026 to formalize entry into the broader European Union.
During the event, HISTRANGER will run continuous live demonstrations of its PMF camera technology, targeting paid enterprise PoCs with European film distributors, gaming publishers, and market research agencies, while exploring embedded software alliances with automotive tier-1 suppliers and robotics manufacturers. Backed by registered domestic patents and pending applications in the United States, under the PCT, and in Japan, the company is currently closing a Pre-Series A investment round to establish localized data processing infrastructure, address regional privacy compliance frameworks, including the GDPR, and accelerate expansion across Europe, North America, and Japan.
