MNTSQ, Adopted by 8 of Top 10 Domestic Companies by Sales, Surpasses 2,000 Adopting Companies and Launches First Large-Scale Promotional Campaign

MNTSQ Inc. (Headquarters: Chuo-ku, Tokyo; Representative Director: Ryuhei Itaya; hereinafter "the Company") is launching its first large-scale media promotion campaign, linking YouTube ads, taxi ads, and outdoor advertising (OOH) primarily around Tokyo Station and Otemachi, to commemorate surpassing 2,000 adopting companies. YouTube ads began airing in June 2026, with taxi and outdoor advertising commencing on July 6 (Mon).

Background of the Promotion

The Company's vision is to "Make All Agreements Fair," and it provides the contract platform "MNTSQ CLM" utilizing cutting-edge technology. With the advancement of DX and the globalization of business, the complexity and sophistication of contract and legal affairs within companies are accelerating. To respond to these changes in the business environment, the Company has focused on developing its product as "Legal AI Infrastructure" that supports the entire contract process, from initial consultation to contract management, rather than individual AI tools.

As a result, "MNTSQ CLM" is currently adopted by 8 of the top 10 domestic listed companies by sales (※1), and the number of adopting companies has surpassed 2,000 (※2). Furthermore, "MNTSQ AI Agent," which has been progressively implemented since September 2025, is increasingly being utilized as a function where legal AI supports departments across the organization, from business divisions to legal departments, in everything from case consultation to contract management.

Building on this track record, we are conducting our first full-scale promotional campaign to expand awareness among companies that are not yet familiar with MNTSQ.

(※2) As of May 2026, including group companies.

◾️ Promotional Graphics

Ideally, all contracts should be equitable and fair. However, in the reality of the business world, "unfair agreements" often arise due to disparities in specialized knowledge and information.

With the vision of solving this structural issue, our promotional graphics express the realization of optimal contracts for both parties involved in a contract (Party A and Party B), and a future where companies and employees thrive through the acceleration of contract operations.
