Leach Inc. announced a comprehensive renewal of its "Leach Generative AI Consultant" service, effective May 1, 2026. The revamped service introduces immediate chat support and a new AI audit service, offering a clear pricing structure starting from 50,000 JPY per month (excluding tax). It aims to be a new form of DX consulting that accompanies SMEs from "consultation" to "execution" in their AI transformation, acting as a "technical gatekeeper."

Leach Inc. (Headquarters: Minato-ku, Tokyo; Representative Director: Takuya Tominaga; hereinafter "Leach") will comprehensively renew its technical advisory service "Leach Generative AI Consultant," which has been well-received since its launch in May 2025, on May 1, 2026.
The traditional concept of "providing consistent accompaniment from strategy formulation to implementation and operation" remains, while new features include an immediate chat response system and an AI audit service. With a transparent pricing structure starting from 50,000 JPY per month (excluding tax), Leach proposes a new form of DX consulting that accompanies SMEs from "consultation" to "execution" in their AI transformation.
The strengthened points of this renewal are the immediate chat-based response and the role of a "technical gatekeeper" that scrutinizes external vendor proposals from a third-party perspective. This is a fundamental update based on the experience of supporting over 40 clients, including individuals.
Furthermore, Representative Tominaga is well-versed in the latest technological trends, having won consecutive awards at the YC-certified hackathon "c0mpiled-7: San Fransokyo" and Builders Weekend 2026 Tokyo in March 2026.
Background of the Renewal ── "Real Issues" Revealed by One Year of Support
Since the service launch in May 2025, Leach has supported over 40 companies and organizations, including individuals, in adopting generative AI. Leach's strength lies in its extensive track record of supporting a wide range of industries and scales, including MINATO HD Group (listed on the Tokyo Stock Exchange Standard Market), Rikiman Inc., Nabel Co., Ltd., and Mizunara Inc., accompanying them in generative AI utilization in various on-site settings.
In this process, what was repeatedly observed was the reality that "one-off advice does not advance corporate AI transformation." Initially, consultations focused on strategy formulation and PoC support, but on-site, challenges extended beyond the scope of generative AI, such as undeveloped infrastructure and external vendor estimates being nearly double the market rate.
In one case, a system development estimate of 1.7 million JPY was scrutinized and reduced to 1 million JPY. We also received numerous consultations such as "PoC is over, but we can't proceed to production implementation" and "We lack personnel who can judge the technical validity of proposals."
A survey by the Ministry of Economy, Trade and Industry shows that the AI adoption rate among SMEs remains less than half that of large enterprises, with a shortage of technical talent and dependence on external vendors being major barriers. Representative Tominaga reflects:
"After leaving my previous job, I visited various workplaces. People were comparing monitors with rulers. People were repeatedly copying and pasting manually. While AI and DX were being discussed overhead, people on the ground were exhausted. I intuitively felt that generative AI could change this situation.
What was needed was not an 'AI teacher' but a 'gatekeeper' who could observe the現場 (workplace) and collaboratively consider optimal AI utilization. Providing consistent support for strategy formulation advice, scrutiny of external vendor proposals, and specific tool implementation support – this integrated approach was what SMEs needed."
By systematizing this support experience, Leach has fundamentally evolved its traditional technical advisory service into this renewal.
Three Key Points of the Renewal ── What Will Change
The main changes from the conventional service are the following three points:
- Evolution to an immediate response system: From the traditional advisory model, it evolves to an immediate response model that returns the first reply within principle 30 minutes, primarily via chat (centered on Slack). By not using email or inquiry forms, the speed of on-site decision-making will significantly improve.
- Establishment of AI audit service: In addition to strategy and PoC support, a new "AI Audit Service" is established to scrutinize the validity of external vendor proposals. As a "technical gatekeeper," it will evaluate development estimates and proposals from a third-party perspective.
- Clear pricing structure: From conventional individual quotes, it shifts to a three-plan system of 50,000 JPY, 150,000 JPY, and 300,000 JPY per month. Companies can choose according to their size and challenges, lowering the hurdle for budget consideration.
Value Continued to Be Provided
The following elements, which have been well-received in the conventional service, will continue to be provided after the renewal:
- Consistent accompaniment from strategy formulation to operation: We will continue to provide support based on specialized knowledge at all phases, including generative AI adoption strategy, use case selection, PoC planning and execution, development and implementation, and operation and improvement.
- Specialization in small and medium-sized enterprises: We propose realistic and cost-effective AI utilization plans to maximize results with limited resources.
- Perspective of in-house capability building support: We provide long-term support to help customers build a system to utilize AI themselves in the future.
