Leach Inc. (Headquarters: Tokyo, Representative Director: Takuya Tominaga, hereinafter "the Company") officially announces its "AI Business OS" concept, which aims to completely overhaul business processes for small and medium-sized enterprises (SMEs) across various industries. As a first step, we are simultaneously developing a suite of vertical SaaS products specialized for six industries: manufacturing, food event management, material leasing, recruitment agencies, SME logistics, and industrial waste management, with sequential releases planned.
In parallel, the Company also provides cross-industry AI tools "Tsuigo.com" and "Saturn," pursuing a strategy to promote both individual task automation and the OS-ification of entire industries.
Why "Industry-Specific AI" Now? — The Limits of Horizontal SaaS and the Reality of SME DX
The Real Reason Why SME DX Isn't Progressing
According to a survey by the Ministry of Economy, Trade and Industry, the DX promotion rate among Japanese SMEs remains low. While the adoption of cloud accounting and chat tools has progressed, the core parts of business operations—order processing, invoice reconciliation, dispatch planning, and administrative responses—still largely rely on traditional methods.
The reasons are not simple. However, our experience supporting over 40 SMEs (including individuals) has revealed one clear structural problem:
The barrier that "horizontal SaaS cannot adapt to industry-specific business workflows."
For example, in manufacturing sites, order forms arriving by fax are still manually entered into core systems. In transportation companies, it's not uncommon for operators to plan dispatches using phones and whiteboards. Industrial waste operators spend enormous amounts of time each month managing paper manifest deadlines. Recruitment agents manually write each proposal for candidates.
Introducing generic project management tools or CRMs does not alleviate these challenges. This is because each industry has its own terminology, business practices, legal regulations, and document formats, creating a "gap" that horizontal tools cannot fully absorb.
Vertical SaaS x AI: The Solution
The "AI Business OS" proposed by our company is an architecture designed to bridge this gap.
The concept is simple: place AI, which deeply understands the business processes of each industry, at its core, and provide end-to-end functions necessary for that industry. Instead of being a general-purpose AI assistant that "can do anything but nothing deeply," we aim for a system where specialized AI, well-versed in the context of a specific industry, handles everything from order reception to billing.
While horizontal SaaS sells "functions," AI Business OS provides "the business process itself." Companies adopting it do not need to worry about combining individual functions; by simply choosing the OS suited to their industry, they can realize a world where major operations are automated and optimized by AI.
For SMEs, an "easy-to-use system" is one that can be immediately integrated into operations after introduction. There is no room for dedicated IT staff for setup and operation. Because AI with pre-existing industry-specific knowledge is used, by simply choosing the OS suited to their industry, it can be used on-site from the following week. AI Business OS aims for such "business transformation with near-zero implementation cost."
AI Business OS — The Full Scope of 7 Products
The AI Business OS being developed by our company consists of the following 7 products. Each product can be used independently while sharing a common AI foundation and design philosophy.
1. FactoryOS: AI Business OS for High-Mix, Low-Volume Manufacturing
https://factoryos.leach.co.jp
The biggest pain point for high-mix, low-volume manufacturing sites is the enormous amount of time spent on manual order entry and drawing searches.
FactoryOS automatically reads order forms received via fax or PDF using OCR, importing part numbers, quantities, and delivery dates as structured data. It then connects production progress management, inventory allocation, and shipping instructions in a single pipeline, and implements an AI drawing search function that can instantly identify "which past drawing corresponds to this part" based on natural language or sketch-like input. This transforms tacit knowledge, often held only by veteran employees, into digital assets.
Estimated effect of introduction: Reduction of approximately 3 hours of manual entry work per day to zero.
In manufacturing sites, tacit knowledge, often residing only in the minds of veteran employees, drives operations. FactoryOS's AI drawing search stores past drawings and specifications in a vector database, allowing similar drawings to be retrieved from natural language or sketch-like input. Converting individualized knowledge into digital assets is the core value of FactoryOS.
2. FestOS: AI Business OS for Food Event and Festival Management
https://festos.leach.co.jp
FestOS centers on automatic generation and checking of documents for public health centers, communication management with exhibitors, and automatic reconciliation of payment data.
In parallel, the Company also provides cross-industry AI tools "Tsuigo.com" and "Saturn," pursuing a strategy to promote both individual task automation and the OS-ification of entire industries.
