JSOL Forms Japan's First Strategic Partnership with US-Based Replit Inc.

JSOL Corporation (hereinafter, JSOL) has signed Japan's first solution partnership and reseller agreement with Replit Inc. (Headquarters: San Francisco, California, USA; hereinafter, Replit), a rapidly growing AI development platform utilizing vibe coding. Through this alliance, JSOL will promote the adoption of vibe coding in Japan and contribute to improving corporate competitiveness by ensuring compatibility with customers' existing systems and strengthening security.

In recent years, a severe IT talent shortage has been pointed out, and for many companies, the inability to quickly reflect business ideas into systems has become a major management challenge. Against this backdrop, vibe coding has rapidly attracted attention.

Vibe coding is a technology that allows designing and building software, such as applications, simply by instructing AI in natural languages like Japanese. Even people without specialized programming knowledge can tell the AI in Japanese, "I want to create this kind of app," and the AI automatically generates and executes the program. This allows AI to replace many processes, from design to publication, traditionally handled by developers. However, companies faced the following hurdles when introducing vibe coding into their actual operations:
- Difficulty in smoothly integrating with existing in-house systems
- Difficulty in addressing security, internal regulations, and governance
- Difficulty in evaluating and judging developed systems to link them to new businesses or business improvements

Replit is a cloud-based development platform that allows vibe coding to be completed entirely in a browser. While existing AI coding assistance tools enhance the efficiency of engineers, Replit is fundamentally different in that it is designed to enable even non-engineers to handle system development itself. It requires no installation, supports instructions in Japanese, and AI agents provide end-to-end support from application planning and design to implementation and publication. Its main feature is that it can be used without specialized programming knowledge. Business users can simply input ideas in Japanese, and a working prototype can be completed in a short time, significantly shortening the "time from conceiving an idea to verifying a working product." Specifically, there have been cases where prototype development, which previously took about two weeks from requirements definition to implementation and verification, was completed in as little as two days using this solution.

Introducing companies can expect the following changes:
- Realize現場主導のシステム改善 (On-site-led system improvements): Business users themselves can create and verify prototypes without waiting for requests to the IT department.
- Dramatically accelerate the idea verification cycle: The cost of "trying things out" decreases, creating an environment where new services can be tested without fear of failure.
- Reduce outsourcing costs and improve in-house development rates: A part of development can be covered in-house, improving efficiency in terms of both cost and time.

In fact, Replit is already being used in the actual operations of major companies such as Zillow, Atlassian, Adobe, Accenture, and Databricks, and recently, they announced the high-performance development agent "Agent 4."

JSOL will utilize its many years of system integration expertise to provide the following supplementary support to promote the introduction and utilization of Replit, which has strong development capabilities, in Japanese enterprise environments. This will ensure that Replit's speed is maintained while achieving implementations that balance the quality, safety, and stability demanded by enterprises:
- Accompaniment for new businesses and business development: For an idea to become a successful business, evaluation from a business perspective, not just technology, is essential. JSOL will accompany clients from the planning stage and support them in linking developed systems to actual business value.
- Integration with existing systems: Systems cannot be used in actual operations if they are not connected to existing in-house systems. JSOL will support the design and implementation of connections with core systems, enabling their introduction in a way that actually works on-site.
- Guarantee of security and quality: To ensure that AI-generated code meets corporate security standards and industry regulations, JSOL will provide support in accordance with the strict standards of each industry, elevating AI-generated code to a "level that can be utilized long-term as a corporate business asset."
- Stable operation after introduction: JSOL will provide continuous support systems and operational design, creating an environment where users can continue to use the system with peace of mind after introduction, while managing security risks.

This partnership was realized through the SMFG Silicon Valley Digital Innovation Lab, which is committed to discovering promising US startups and bridging them with Japanese companies.

Through this partnership, both companies will jointly market the product.
