Our performance has been growing year by year, and particularly in the fiscal year 2023, with the explosive spread of generative AI, it is predicted that 40% of enterprise applications will incorporate conversational AI by 2024, creating a favorable market wind. Our sales for the fiscal year 2023 reached approximately 8.3 billion yen, and we have expanded to about 400 members in the main office alone. Additionally, with the acquisition of two subsidiaries and the integration of one company into our group, our business environment is dynamically evolving. We are seeking new colleagues to help us realize new services and businesses aimed at solving social issues.## Product OverviewIn Japan, where the decline in the productive labor population is progressing, it is predicted that an economic loss of 12 trillion yen per year will occur due to delays in digital transformation (DX).
