Korean startup using voice analysis to detect brain changes wins Disrupt 2027 pitch spot

Nine early-stage South Korean startups competed this week at the DETO 2026 technology conference in Seoul for a chance to join next year’s Startup Battlefield 200 competition at TechCrunch Disrupt 2027. The winner, Voinosis, develops an AI tool that analyzes speech patterns — including pitch, pauses, rhythm and response times — to detect changes linked to brain health. Each voice check takes less than five minutes and has been tested in Greek, Japanese and English without requiring separate language training. In a clinical study of 146 participants, the company reports 88% accuracy in screening for potential cognitive issues.

The other eight startups span deep tech fields such as healthcare, fintech, energy, semiconductors and AI. Awesome Lab makes a heating system that uses water electrolysis and ionization to generate heat for buildings and industrial processes, and plans to supply core OEM modules to U.S. boiler and HVAC companies. Crosshub offers a platform called IDBlock that combines identity verification and payment services using Self-Sovereign Identity and zero-knowledge proof, aimed at travelers and international visitors. DeepFusion AI has developed a 4D radar-based imaging system with additional sensors for autonomous mobility, robotaxi, maritime surveillance and defense applications.

EFLOW produces specialized motors that deliver more torque in a smaller footprint for robots, drones and satellites, and also develops actuators for robotic joint control. Otiton Medical makes two medical devices — one for measuring body temperature and another that captures ear canal images and analyzes the eardrum using AI trained on roughly 55,000 images. Riibotics says it can deploy robots in warehouses within a day by streamlining setup, infrastructure mapping and system integration. Ternell, a semiconductor startup founded by a former Samsung Electronics engineer, is developing a three-state memory called T-SRAM that aims to reduce power consumption in AI chips. Testbank, an edtech startup, makes an app called Solve that converts printed study materials into interactive digital versions with automatic grading.

All nine startups are seeking to enter the U.S. market as part of their international expansion plans. Voinosis was founded by Grace Shin, a former otologic surgeon with more than 25 years of experience, and is currently raising a Series A round with a South Korean pharmaceutical company as a strategic investor.
