Inside Growth Co., Ltd.

Inside Growth Co., Ltd. (インサイドグロース株式会社) is a Japanese human-resources and staffing company headquartered in Osaka. It operates a temporary-dispatch (haken) business focused on office work, and its Osaka branch is best known for specializing in 'non-voice' (非電話・ノンボイス) assignments — jobs that involve email correspondence, chat support, listing moderation and data entry rather than telephone-based call-center work. The company's recruitment page markets these roles to job seekers in the Umeda, Yodoyabashi, Hommachi and Namba areas of Osaka, emphasizing conditions such as daily pay (日払い), no experience required (未経験歓迎), high hourly wages, short commutes near stations, limited overtime, social insurance, and relaxed dress/hair/nail rules. According to public company data, Inside Growth was formerly known as DSP Co., Ltd. and had around 669 employees. Its Osaka branch states that services are managed by a Nationally Certified Career Consultant and a Class I Health Supervisor, indicating a structured approach to placement quality and worker health management. The company has introduced a daily-pay payroll app for dispatched staff, allowing wages to be transferred as often as every day based on work records. The firm positions itself as a provider of 'truly good-condition Osaka dispatch jobs' that are not always listed on general job boards, and it uses a LINE-based automated screening flow to check whether applicants can be introduced to assignments. Typical placements include email support for major flea-market apps, listing-review operations, smartphone-game email support, website post monitoring, and chat customer support. Inside Growth thus sits in Japan's large temporary-staffing and customer-support outsourcing market, differentiated by its focus on quiet, phone-free office environments.
