Leach's Comprehensive Overhaul of Generative AI Consulting Services

In a significant announcement, Leach Co., based in Minato, Tokyo, declared a major enhancement to its generative AI consulting services, set to relaunch on May 1, 2026. The company has previously received acclaim since introducing its service in May 2025, aimed at assisting small to medium enterprises (SMEs) in their AI integration journey.

A Transformative Approach

Leach's redefined service maintains its original concept of providing comprehensive support from strategy formulation to implementation while introducing immediate chat-based support and an AI auditing service. The transparent pricing starts from 50,000 yen per month (tax exclusive), suggesting a new approach to digital transformation consulting that spans from advisory to execution.

The key updates focus on chat-based, instant feedback systems that operate as the “gatekeepers” of technology, ensuring that clients not only receive speedy guidance but also accurate checks of external vendor proposals. With experience spanning over 40 clients, including individual professionals and companies like Minato HD Group and others, the revamped service promises an improved and strategic partnership for AI integration.

Understanding True Challenges

Since its inception, Leach has continuously interacted with various sectors, gaining insights into real-world challenges faced by businesses. CEO Takuya Tominaga reflects on their experience: “Initial consultations largely centered on strategy development or proof of concept (PoC) support. However, we frequently encountered concerns beyond the technical aspects, like inadequate infrastructure and unrealistic vendor quotes.” An example cited includes renegotiating a system development estimate from 1.7 million yen down to 1 million yen.

Moreover, many businesses face hurdles in progressing past their PoCs due to the lack of personnel capable of evaluating technical proposals effectively. According to a survey by the Ministry of Economy, Trade and Industry, the AI adoption rate for SMEs remains less than half that of larger corporations, with talent shortages and reliance on external vendors greatly inhibiting progress.

Tominaga notes, “After my time at Toshiba E&D, I visited various workplaces and saw workers overwhelmed by outdated practices. There’s a significant gap between the conversations surrounding AI and digital transformation at the upper levels versus the struggles faced on the ground.” He concluded that what businesses need is not just an “AI teacher,” but a “gatekeeper” who can navigate complexities within organizations, advise on strategy, scrutinize vendor proposals, and assist in tool implementation.

Key Changes in the New Service

Here are the three key changes within the upcoming service:

1. Immediate Response System: Transition from an advisory model to a chat-based platform (primarily through Slack), promising feedback within 30 minutes. This approach aims to significantly enhance organizational decision-making speed.

2. AI Auditing Service: This new feature provides thorough checks of vendor proposals and development estimates from a neutral standpoint, acting as the “gatekeeper” in the technology landscape.

3. Simplified Pricing Structure: Moving away from individual estimates, Leach has introduced a tiered pricing model comprising three plans at 50,000 yen, 150,000 yen, and 300,000 yen monthly, facilitating straightforward budget considerations for companies of various sizes.

Continued Value Offerings

Despite the changes, Leach will continue to provide critical support in strategy development to implementation, particularly focusing on helping SMEs maximize their resource use and create effective AI utilization plans. The goal is to empower businesses to eventually develop their own internal capabilities in AI, ensuring sustainability beyond initial support.

New Services Launched

The refreshed consulting service has always aimed for instant responses. CEO Takuya Tominaga, who personally oversees client interactions, supports three key areas: generative AI, web applications, and cloud infrastructure.

Each firm can find tailored support and flexibility when engaging with Leach’s consultants. The AI auditing service scrutinizes contracts from vendors on three core aspects: technical feasibility, market average, and alternatives, helping clients save unnecessary costs and invest efficiently in necessary features.

Pricing Plans Tailored for All Companies

Leach provides three pricing plans to cater to diverse business needs:

• - Light Plan: 50,000 yen/month - Ideal for companies starting their AI adoption journey.
• - Standard Plan: 150,000 yen/month - Perfectly suited for those engaging more frequently with external vendors.
• - Premium Plan: 300,000 yen/month - Designed for companies fully committed to pushing forward with AI implementation.

Each plan includes benefits such as monthly meetings and technology advice, with an emphasis on a trial period to allow businesses to evaluate the effectiveness of the service before full commitment.

Commitment to Supporting SMEs

Leach's goal to transform Japan’s digital infrastructure while emphasizing support for SMEs continues through its revamped consulting services. Tominaga directly acknowledges the growing needs of businesses in the evolving landscape of technology and AI, stating that discovering effective, tailored solutions will be paramount going forward.

For interested parties looking to improve their technological landscape, Leach’s consulting service stands ready, backed by strong credentials and proven results.
