Leach Co., Ltd. (Headquarters: Minato-ku, Tokyo, CEO: Takuya Tominaga) has been selected for "E2B for Startups", a startup support program provided by E2B.
Through this selection, Leach will acquire $20,000 USD worth of E2B credits, access to all features of the E2B Pro tier, and a direct collaboration channel with E2B's engineering team. With this, the company will further strengthen the AI agent capabilities in its own products—such as the document matching AI cloud "Totsugo.com", the AI-powered business automation platform "Saturn", and its industry-specific AI business OS series (FactoryOS / BuildOS / LogiOS)—on a globally standard sandbox infrastructure.
Key Points of this Release
The three key points to note in this press release are:
Official Partnership with a Global Standard: Secured an official partnership with E2B, a YCombinator-backed global standard for AI sandboxes.
Feature Enhancement of In-house Products: Directly connecting to the enhancement of AI agent functions for the document matching AI "Totsugo.com", AI business automation "Saturn", and industry-specific AI business OS "FactoryOS / BuildOS / LogiOS".
Completion of a Three-Layered Partnership: Following Cloudflare for Startups and the Tokyo Acceleration Program, a development structure cooperating with external partners across three layers—infrastructure, AI execution, and business strategy—has been completed.
About E2B ── The Sandbox Infrastructure Supporting the AI Agent Era
E2B is a company providing a cloud sandbox environment for AI agents to securely execute code. Backed by YCombinator, it enables the real-time execution of AI-generated code, data analysis, and file operations within an isolated, secure environment. Adopted by AI developers worldwide, it is gaining attention as a foundational infrastructure for AI agent development.
The scenarios in which AI agents are utilized in practical business are rapidly expanding. In situations where AI runs programs—such as automated code generation, data preprocessing, and document conversion processes—a "secure execution environment" is indispensable. E2B's sandbox executes AI-generated code in an environment isolated from the host system, preventing unexpected malicious processing or resource overconsumption.
With a startup time of under 100 milliseconds, it can run thousands of sandboxes concurrently, ensuring the scalability of AI agents. It supports major languages such as Python, Node.js, Bash, and R, and allows fine-grained configuration of file systems and network controls.
Details of the Selection
Through this selection, Leach will receive the following support:
- 20,000 USD worth of E2B credits
- Access to all features of the E2B Pro Tier
- Direct collaboration channel with the E2B engineering team
- Technical architecture consultation support
E2B for Startups is a program targeting startups that develop products with AI agents at their core. The review evaluates the product's technical uniqueness, the extent of AI agent utilization, and the business's growth potential.
Leach's Utilization Policy ── Infrastructure for AI Agents to Safely Write and Execute Code
Our company develops and operates multiple SaaS products, including the document matching AI cloud "Totsugo.com" and the AI-powered business automation platform "Saturn". All of these products adopt AI agents as their core technology, utilizing an architecture where "AI autonomously performs data processing and code execution based on user instructions."
By leveraging E2B's sandbox environment, we plan to implement the following technical improvements:
Saturn (AI Business Automation): Enhancing the functionality where AI agents automatically generate and execute Python scripts based on user-defined business workflows. We will build a mechanism to safely execute data retrieval from COREC, invoice data generation to freee, and data processing/conversion within the sandbox.
Totsugo.com (Document Matching AI): Introducing AI agents to the data cleansing process after OCR reading to improve the automatic normalization accuracy of notational variations. This enables custom rules for each user to be executed securely within the sandbox.
Industry-Specific AI Business OS: In the development of FactoryOS, BuildOS, LogiOS, etc., AI processing pipelines tailored to data formats unique to each industry will be isolated and executed in the sandbox, ensuring thorough data separation between tenants.
Through this selection, Leach will acquire $20,000 USD worth of E2B credits, access to all features of the E2B Pro tier, and a direct collaboration channel with E2B's engineering team. With this, the company will further strengthen the AI agent capabilities in its own products—such as the document matching AI cloud "Totsugo.com", the AI-powered business automation platform "Saturn", and its industry-specific AI business OS series (FactoryOS / BuildOS / LogiOS)—on a globally standard sandbox infrastructure.
