What Seisgadget does

Seisgadget Ltd. (サイスガジェット株式会社) is a Tokyo-based marine survey technology company founded on February 18, 2013 that provides marine geophysical survey equipment, marine robotics, and related technical services to offshore wind developers, oil and gas companies, academic and government research institutions, and marine infrastructure operators. The company operates from its headquarters in Ōta-ku, Ōmori-Kita, Tokyo (relocated June 2022) and runs two business lines: a marine physical survey division offering seismic survey systems, the proprietary OBS2G ocean bottom seismometer series (including the OBS2G-SP CCS/CCUS monitoring variant), DUG-powered high-performance data processing services (HPCaaS), and equipment sales/rental/maintenance; and a marine robotics division (RAS — Robotics and Autonomous Solutions, established January 2023) that distributes and integrates the IVM Technologies HYDRO underwater photogrammetry series, Kraken Robotics Acoustic Corer and Sub-Bottom Imager, Ocius Technology Bluebottle USV, and Subsea Tech SeaCAT USV.

Revenue is generated through a hybrid model combining unit-level and turnkey hardware sales, equipment rental (most recently a HYDRO 100 rental launched November 2024), professional technical and survey support services, and Data-as-a-Service offerings. The company serves customers primarily through direct enterprise sales, website inquiry, and trade show participation (WIND EXPO, CSPI-EXPO, Ocean Biz). Pricing is quote-based and not publicly disclosed. Seisgadget's own proprietary technology is the OBS2G seismometer series; the remainder of its robotics portfolio is sourced through exclusive Japan distribution partnerships with global technology developers, allowing the company to function as a one-stop marine survey systems integrator in the domestic market while conducting selected international projects (including North Sea OBS2G trials).

Seisgadget entered a strategic capital partnership with Japan Investment Fund (a joint venture between Japan M&A Center Holdings and the Development Bank of Japan) in May 2022 to fund growth in Japan's expanding offshore wind survey market. Subsequent strategic moves include the launch of the HYDRO Series sales (February 2023), the HYDRO 100 compact photogrammetry device (October 2023), NETIS registration of the HYDRO series under Japan's MLIT (April 2024), and selection for two consecutive Nippon Foundation-DeepStar grants covering CCS/CCUS monitoring and subsea hydrocarbon leakage detection.
