TDE Group, operating through its Hong Kong subsidiary Trumptech Digital Education Services, sells STEAM (science, technology, engineering, arts, and mathematics) education solutions to primary and secondary schools in Hong Kong. TDE's core offerings include on-site instructor-led workshops, student courses covering coding, robotics, AI, and mathematics, teacher training programs, and large-scale interschool competitions such as FIRST LEGO League and AI robot competitions. TDE also sells two proprietary B2B software platforms — CodeN'Sim for coding and AI education and Learnlex for mathematics — primarily as annual subscriptions to schools. Hardware sales consist largely of LEGO Education curriculum kits, which TDE resells as an authorized reseller. A newer consultancy segment provides advisory, education tours, and technical development services. TDE claims to have served over 60% of Hong Kong primary and secondary schools over the past three years. Revenue is largely service-based, with school purchases funded heavily by Hong Kong government STEAM education subsidies, creating meaningful seasonality tied to subsidy cycles and school calendars. The business is small, with roughly $4.6M in annual revenue and 25 employees, with operations entirely concentrated in Hong Kong. TDE's stated growth priorities include developing curriculum and platforms for a new mandatory Primary Science subject in Hong Kong schools, upgrading its CodeN'Sim platform with AI capabilities, and exploring early-stage expansion into ASEAN and Middle East markets.
