Postmath (CEO Choi Jun-ho) , an edutech company that operates ‘Math Secretary’, a math education content DB construction solution, announced that it has successfully turned a profit with sales of 5.56 billion won in just 4.7 years since its founding.
Founded in April 2021, Postmass has grown without a separate marketing or sales organization, focusing on product competitiveness and the voluntary expansion of its training program. Within this structure, the company has established a stable revenue structure, recording operating profit of KRW 100 million and net income of KRW 500 million.
The company's workforce structure also reflects its product- and content-centric strategy. Starting with just 10 employees, the organization has grown to 107 employees, both domestically and internationally. Half of the workforce is comprised of R&D personnel focused on planning and development, while the other half are content specialists. The company maintains a structure where all employees focus on advancing its products and content, and this hiring success has been recognized, leading to its recent selection as an excellent job creator.
Postmath's technological competitiveness is also evident in its data construction speed. In the first four years of its service, it built a database of approximately 1 million mathematical content items. Recently, leveraging the maturation of AI technology and infrastructure expansion, it has added 3.2 million database items in just seven months, bringing its cumulative total to over 4.2 million.
Additionally, in collaboration with AI specialist Mondrian AI, we secured 32 NVIDIA B300 next-generation AI chips. This will enable us to develop advanced AI-based services, including large-scale language models specialized for mathematics.
Postmath is focusing on expanding its educational ecosystem while also generating revenue. Its proprietary mathematical graphics tool, "PostGeo," is distributed free of charge, establishing it as a standard tool used across the industry. It also offers free database construction services to public schools, expanding the number of schools adopting Postmath.
Postmath's achievements have also been recognized in external evaluations. Since being selected for the TIPS program in 2023, it has exceeded its sales, employment, and technology targets, receiving an excellent rating in the final evaluation in 2025. Furthermore, it was selected as an excellent user of the GPU support program by the National IT Industry Promotion Agency (NIPA) and listed in the government's casebook.
CEO Choi Jun-ho explained that the product-centric strategy, which reflects the needs of the educational field, has led to success, and announced plans to expand digital transformation in the global math education market based on AI infrastructure and specialized personnel.
