SpiralAI Introduces 4-Day Work Week for Full-Time Employees with No Salary Reduction

SpiralAI, Inc., a developer of services using AI technologies such as large language models, announced that it has introduced a 4-day work week for full-time employees starting June 1, 2026, with no salary reduction. The policy applies to approximately 20 full-time employees, with every Friday designated as a company-wide holiday. The background for this introduction is that the evolution of generative AI has made many tasks, such as research, summarization, document creation, and development support, more efficient through collaboration with AI. SpiralAI positions this as an organizational strategy to achieve the acquisition and retention of talent required in the AI era and to improve development quality by directing the productivity gained from AI utilization toward time for employees to learn, create, and rest, rather than additional work. CEO Yuichi Sasaki commented, 'The 4-day work week is a challenge to increase life experience, deepen contemplation, and continue exploring technology and expression through having spare time.'
