About Caster

Caster Co., Ltd. operates as a key player in the human resources sector, centered on the mission of making remote work a standard practice. The company was founded in September 2014 by Shota Nakagawa, who currently serves as the Representative Director. Nakagawa's journey began with running a vintage clothing store, where he realized the immense power of the internet. This realization prompted him to enter the IT industry, working for companies like Opt, Inc. and E-guardian Inc. During his time in outsourcing, he observed the growing demand for remote work opportunities and the often-unfavorable conditions faced by online workers, which inspired him to establish Caster.

The firm's core business revolves around its Workspace as a Service (WaaS) offerings, most notably the "CASTER BIZ" series. This suite provides remote assistant services covering a wide spectrum of back-office operations, including secretarial tasks, accounting, human resources, recruiting, and marketing, primarily serving startups and other businesses in Japan and Germany. Revenue is generated through a subscription-based model where clients contract for a set number of hours, which can be flexibly used across various specialties. This approach allows companies, particularly startups, to access a diverse pool of skilled professionals for different functions under a single contract, without the need for direct hiring and management.

Caster's service portfolio is extensive, featuring specialized solutions like "CASTER BIZ recruiting" for hiring support, "CASTER BIZ accounting" for financial tasks, and "CASTER BIZ sales marketing". Beyond the BIZ series, the company offers "Zaitaku Haken," a remote temporary staffing service, "Reworker," a job board specifically for remote positions, and "My Assistant" for smaller, routine tasks. A distinctive aspect of Caster's model is that its remote workers are full-time, vetted employees, ensuring reliability for clients. The company has also expanded into consulting with "Caster Anywhere," helping other businesses transition to and build remote work organizational structures. Recently, Caster has been accelerating its Business Process as a Service (BPaaS) offerings, partnering with SaaS vendors to combine technology with its human resource services, such as a collaboration with MetaMoJi to support the construction industry.
