Marubeni Information Systems Co., Ltd. (President: Sato Hirofumi), part of the Marubeni I-DIGIO Group's Advanced Integration Segment (Segment CEO: Yamanaka Shigeo), is launching "Marucha," a generative AI platform used by over 10,000 monthly active users within the Marubeni Group, for external corporate clients.
In recent years, while expectations for generative AI utilization are high across many companies, full-scale adoption is often hindered by reasons such as "difficulty in choosing the right LLM," "concerns about security and governance," and "inability to establish a company-wide deployment infrastructure in a short period and at low cost." Furthermore, knowledge such as internal regulations, manuals, FAQs, and proposal documents being scattered across departments, making it difficult to quickly access necessary information, and customer support inquiries concentrating in specific departments, also pose barriers to productivity improvement.
"Marucha" is a generative AI platform service that solves these challenges. Its functionalities have been refined through actual operation within the Marubeni Group, boasting a track record of over 10,000 active users. This AI infrastructure, which has withstood large-scale operations rather than just Proof of Concept (PoC), can be immediately introduced as a SaaS. It flexibly utilizes optimal models according to use cases and business requirements by supporting multiple latest LLMs such as GPT, Claude, Gemini, and Perplexity. It provides one-stop solutions for practical tasks, including drafting emails and reports, summarizing, translating, organizing ideas, analyzing files like PDFs and Excel, high-precision RAG for cross-searching internal documents, meeting minute generation support, and rich PowerPoint presentation creation.
Automatic generation and summarization of meeting minutes based on conference audio and video files significantly reduce the burden of record creation after meetings. Support for creating PowerPoint presentations, including structure, headings, body text, and even diagrams, upon instruction, accelerates the speed of creating proposals and reports. Cross-searching and referencing internal regulations, business manuals, news, and past documents, with answers accompanied by source URLs and reference information, supports the efficiency of inquiry response and the advancement of knowledge utilization. Furthermore, by creating and deploying custom agents tailored to the needs of specific businesses or departments, it accelerates AI utilization specialized for purposes such as legal, HR, general affairs, and sales support.
▼ List of Major Functions
On the technical side, it implements Agentic RAG, a mechanism for document retrieval involving AI agent reasoning and structuring, and high-precision structuring that appropriately interprets PDF, table, and list structures. By incorporating internal company information into the AI's knowledge base, it enables responses to questions related to multiple documents and complex regulation checks, realizing an AI platform infrastructure adapted for use by companies that prioritize accuracy, transparency, and explainability.
"Marucha" is designed with security and control as prerequisites. It supports the governance required for corporate use, including log and audit trail management, access control, usage function restrictions, and control over file upload permissions, providing a secure usage environment based on the premise that input data is not secondarily used for model training. As a platform for the Marubeni Group, which operates globally, it is designed for diverse users to utilize as a common infrastructure.
When companies build an AI infrastructure from scratch, significant initial investment and specialized personnel are required for LLM connection, authentication, log management, access control, document retrieval, application integration, and operation/maintenance. In contrast, "Marucha" allows for rapid and inexpensive adoption of a rich AI infrastructure environment, honed through use within the Marubeni Group, as a SaaS. Furthermore, it adopts a tenant-provision model based on usage volume rather than per-user licensing, optimizing costs for company-wide adoption, including departments with low usage.
Leveraging its expertise in generative AI and enterprise system implementation, the Marubeni I-DIGIO Group provides comprehensive support, from the introduction of "Marucha" to its operational stabilization and expansion of use. By further strengthening generative AI utilization tailored to customer business challenges, it contributes to customer business transformation and enhanced competitiveness through the advancement and efficiency of operations and the promotion of knowledge utilization.
