What DOIT does

DOIT (주식회사두잇) is a Daejeon, South Korea-based disaster prevention and structural health monitoring company founded in November 2017. The company develops and manufactures proprietary MEMS-based seismic instrumentation — most notably the MA301+ accelerometer with an embedded P-wave earthquake early warning algorithm that received Korean Ministry of Land, Infrastructure and Transport innovative product certification in 2021 — alongside geophone-based micro-vibration sensors (MA301+G), data collection units (ICU-X2), and earthquake intensity predictors (EQ-Alarmer). Its core technology stack combines low-noise MEMS sensing, frequency-domain and hodogram-based structural damage analytics, IoT-based safety management, and AI-driven monitoring for mining and infrastructure applications.

Beyond its proprietary products, DOIT operates as the exclusive Korean agent for at least nine international principals covering complementary domains: Kinemetrics and SARA (seismic sensors and software), Pavemetrics and ROMDAS (laser rail, road, tunnel, and runway inspection), ROXON (conveyor belt monitoring), Rolabs (remote heavy equipment control), HC Robotics (AI, drones, EOIR cameras, edge-AI services), Giatec (concrete testing), Senceive and ACKCIO (slope and wireless monitoring), and SOMMER/Epiroc (radar flow and rockfall detection). This distribution breadth enables the company to bid as an integrated solutions provider across government and enterprise tenders.

DOIT serves primarily Korean government agencies, state-owned enterprises, research institutes, and large private companies through public procurement tenders and direct contracts. Reported customers include Korea Meteorological Administration, Korea Railroad Corporation, Korea Hydro & Nuclear Power, Korea Electric Power Corporation, Korea Airport Corporation, Korea Atomic Energy Environmental Corporation, Samsung Electronics, and major mining and construction firms. Revenue is generated from hardware sales, system integration and installation, multi-year maintenance contracts (1-3 years), software licenses and upgrades, and agency commissions. The company is pursuing international expansion, evidenced by its first overseas distributor agreement (Philippines, May 2025) and CE certification of core products (January 2026).
