JJ&COMPANIES develops a proprietary portfolio of offshore plant process control technologies, including its flagship J-IAS integrated control system for eco-friendly gas-fueled vessels, LNG fuel gas supply control systems, vision AI fire-detection systems, and underwater biological data analysis tools. J-IAS has been delivered to more than 23 ships owned by operators in South Korea, Greece, and Singapore, and has earned certifications from KR, DNV, and ABS while meeting IACS cybersecurity (E27) standards. The company was founded by engineers with over a decade of experience at global offshore engineering firms and has been selected for five national government support programs, reflecting validated technical competitiveness. JJ&COMPANIES has established a U.S. subsidiary in Seattle to pursue entry into the U.S. shipbuilding industry and is preparing to expand into sustainable marine fuel production and supply. The recent Series A increased its total funding to over KRW 3 billion (about $1.96M), which management says will support its global expansion efforts.
