Atsumell Inc. (Headquarters: 1-8-1 Nihonbashi Kayabacho, Chuo-ku, Tokyo; Representative Director: Kunitomo Yamaguchi; hereinafter "Our Company"), which is working to solve structural issues in the system development industry, is pleased to announce that its guided AI agent "Kakusill," which actively collects and manages tacit knowledge, has been introduced to "ProWith," a professional staffing service operated by Another Works Inc. (Headquarters: Minato-ku, Tokyo; President and CEO: Naotomo Obayashi).
This introduction merges the know-how in requirement organization and personnel requirement design accumulated by Another Works Inc. with Atsumell's AI requirement definition automation technology. We will jointly promote the creation of an environment where more companies can seamlessly utilize specialized human resources without rework, by significantly shortening the lead time from problem identification to project launch through "ProWith."
Background of Introduction and Social Issues to be Solved -- The Challenge of "Requirement Definition and Verbalization" Hindering Human Resource Utilization
Amidst a deepening shortage of specialized human resources in many companies due to the declining working population caused by an aging society and the acceleration of DX promotion, there is a surge in companies incorporating immediate-impact professionals through side jobs and contract work. However, many companies hesitate to onboard external talent because they "have issues but cannot properly verbalize and organize the request details as requirements."
Even in the AI-driven development era, the inability to correctly convey the "tacit knowledge" and "preconditions" of the field, which are not verbalized, as input information to AI or external personnel has been the biggest bottleneck in development projects and the utilization of specialized human resources.
What Will Be Achieved with This Introduction -- Accelerating Matching and Project Launch on "ProWith"
By combining the know-how in supporting side-job talent utilization cultivated by Another Works Inc. with Kakusill's active structuring and specification functions, the following values will be provided:
Shortened Lead Time from Problem Identification to Project Launch for "ProWith" User Companies
By inputting the challenges and request details faced by companies into "Kakusill," the guided AI agent will proactively extract and structure unverbalized demands and requirements. This will dramatically reduce communication costs associated with launching contract work and development projects through "ProWith."
Lowering the Hurdle for Onboarding External Talent and Maximizing Opportunities for Challenge
By reducing the burden of requirement definition, an environment will be created where companies that previously felt a hurdle in onboarding side-job or contract talent can more easily consider utilizing external human resources. The aim is to reach a state where companies can onboard professionals with the necessary skills at the necessary times, thereby supporting business growth.
What is Kakusill? -- A Specification Editor Where AI Actively Collects and Manages Tacit Knowledge
Kakusill is a specification editor designed to eliminate rework in the AI-driven development era by having AI collect and manage tacit knowledge in system development. It is not merely a document management tool. AI "proactively" extracts tacit knowledge and unifies team understanding. Even those new to requirement definition using AI can smoothly implement Kakusill, as its guided AI agent navigates each step of the process.
About Another Works Inc.
Another Works Inc. aims to create a society where new challenges and possibilities expand through "side jobs," with the vision of "Maximizing opportunities for all who take on challenges." Its flagship business, the side-job matching platform "Fukugyo Cloud," has surpassed 100,000 registered talents, 2,500 implementations, and 250 local government implementations cumulatively as of June 2026. The company promotes the social implementation of side jobs that leverage individual skills.
Comments from Representatives
"The insights and know-how gained from external professional human resources are extremely valuable, but it still requires a lot of manual work and experience to translate them into requirements and specifications that can be practically used on the project site.
Kakusill is a product that structures such valuable knowledge (tacit knowledge) using AI and transforms it into a 'common language' for anyone to promote projects immediately. Through this introduction to Another Works, we will make the onboarding of side-job and contract talent more accessible, and together create a state where companies can advance new business development and DX promotion more quickly and reliably."
