Seoul selection: the road to Disrupt 2027

TechCrunch's annual Startup Battlefield 200 competition gathers hundreds of companies from around the world vying for the chance to pitch in front of venture investors and the international tech community at the Disrupt conference. This week, nine early-stage South Korean startups presented their projects at the DETO 2026 conference in Seoul, competing for a spot on next year's list. Voinosis took the win, while the other eight companies earned the opportunity to make the competition's shortlist. All nine startups operate in the deep tech sector — from healthcare and fintech to energy, semiconductors, and AI — and all are targeting entry into the US market as part of broader international expansion plans.

The winner: Voinosis and voice-based brain diagnostics

Voinosis is developing an AI tool that analyzes speech patterns — pitch, pauses, rhythm, and reaction time — to detect changes associated with brain health. Each voice check takes less than five minutes. According to the company, the technology has been tested in Greek, Japanese, and English and does not require separate training for each language; in a clinical study with 146 participants, the startup claims it demonstrated 88% accuracy in screening for potential cognitive issues. The target audience includes hospitals, nursing homes, insurers, and individual consumers; the company also plans to link voice checks with cognitive training, assessments, and treatment by medical specialists. The founder is Grace Shin, who worked as an otolaryngologist (ear surgeon) for more than 25 years; the startup is currently raising a Series A round and has already secured a strategic investment from a South Korean pharmaceutical company.

The other participants: from thermal systems to edtech

Awesome Lab from Seoul manufactures ThermoFlux — a heating system based on water electrolysis and ionization for buildings, hot water supply, and industrial processes; in the US, the company plans to supply OEM modules and partner with manufacturers of boilers, water heaters, and HVAC equipment. Crosshub is developing the IDBlock platform, which combines identity verification and payments based on Self-Sovereign Identity and zero-knowledge proofs — for travelers and foreign guests. DeepFusion AI has created a 4D radar imaging system with additional sensors for autonomous mobility, robotaxis, maritime surveillance, and defense. EFLOW makes compact high-torque electric motors for robots, drones, and satellites, as well as actuators for robotic joints. Otiton Medical produces two medical devices — a thermometer and a device for capturing images of the ear canal and analyzing the eardrum; the AI was trained on approximately 55,000 images, and the device is certified in South Korea. Riibotics claims it can deploy robots in a warehouse in a single day, simplifying infrastructure, mapping, integration, and safety checks. Ternell from Ulsan is developing T-SRAM memory with a third state to reduce the power consumption of AI chips: according to the company, tests on 28-nanometer chips showed a 33–102% increase in capacity and a 55–71% reduction in data access energy compared to conventional SRAM; the founder is KyungRok Kim, a former Samsung Electronics engineer. Testbank is developing the Solve app, which turns printed educational materials into interactive digital versions with automatic answer checking.
