The company serves four end verticals — display, semiconductor, automotive, and secondary battery — through custom-engineered equipment addressing each segment's reliability qualification requirements (HAST chambers, SSD aging, wafer bake ovens, automotive composite environment chambers, BMS reliability testers).

The company operates a direct B2B enterprise sales model with deep embedment into the Korean chaebol supply chain. Innotech holds 1st-tier supplier registrations with Samsung Display (since 2019, the primary customer driving foldable equipment revenue), Samsung Electronics Wireless Division (since 2021), Samsung SDI (since 2022-2023), and Hyundai Mobis (since 2022). Equipment is custom-built per customer specification, resulting in long project-based sales cycles and high contract values. The company is backed by ~137 billion KRW in cumulative disclosed funding from Shinbo, KB Securities, SBI Investment, and Yuanta Securities, and holds 10+ Korean patents covering flexible display testing, thermal shock methods, autoclave systems, and high-altitude display transport testing.

Innotech is currently preparing for a KOSDAQ listing, having filed a securities registration statement with Korea's Financial Supervisory Service in September 2025. The company has expanded internationally with a Vietnam branch established in 2024 and has scaled exports from $1M (2020) to $10M+ (2025), earning the Export Tower award. Government-recognized designations include Materials-Parts-Equipment Specialized Company, Innovative Management SME, ISO 9001 and ISO 14001 certifications, and a 2025 Presidential Commendation for SME innovation. Revenue model is one-time hardware sales of custom-built equipment, with no publicly disclosed pricing.
