~Integrating "GMO Rental DX Tenant App/Web" with "mamorocca"~

　GMO ReTech, Inc. (President and CEO: Akito Suzuki, hereinafter referred to as GMO ReTech), a member of the GMO Internet Group, has entered into a business alliance agreement with Vanguard Smith Co., Ltd. (President and CEO: Keita Tanaka, hereinafter referred to as Vanguard Smith, TSE PRO Securities Code: 511A) on Monday, June 29, 2026.
　This partnership aims to strengthen support for resolving neighborhood disputes in rental property management, enhance the peace of mind of tenants, and reduce the workload of property management companies by integrating the property management company service "GMO Rental DX Tenant App/Web" with the neighborhood dispute resolution support service "mamorocca".
　This will allow residents to access a consultation service without having to search for a place to seek advice, and will also reduce the burden on property management companies in handling inquiries about neighbor disputes.

[Background and Objectives of the Partnership]
　In apartment buildings, neighborly disputes can arise between residents regarding noise, garbage disposal, and other disruptive behaviors. Many of these issues require individual judgment and expert handling, posing challenges for property management companies in terms of workload and the burden on their staff. Conversely, residents may find it difficult to find appropriate resources for resolving these issues, and it can take time to connect with the right support.
　Against this backdrop, GMO ReTech and Vanguard Smith decided to form this business alliance, believing that combining GMO ReTech's connections with real estate management companies and tenants with Vanguard Smith's expertise in handling neighbor disputes would create an environment where tenants feel more comfortable seeking advice, while also reducing the burden on real estate management companies.

[Details of the business partnership]
　Real estate management companies that have implemented both "GMO Rental DX Tenant App/Web" and "mamorocca" can use the following services.

- You can access the consultation desk directly from the "Frequently Asked Questions" section.
　The "Frequently Asked Questions" section within the "GMO Rental DX Tenant App/Web" displays contact information for the "Neighbor Dispute Specialist Hotline" provided by "mamorocca," exclusively for tenants. This allows you to access the hotline without having to search for contact information or check paper notices.

[Benefits of service integration]
- Reduce the effort required for residents to find a consultation service.
　In the event of a problem, tenants can directly access the support desk from the "Frequently Asked Questions" section of the "GMO Rental DX Tenant App/Web." This allows tenants to quickly begin consultation without having to search for a support desk.

- Reduce the burden on property management companies in handling inquiries.
　By creating an environment where residents can easily access the "mamorocca" consultation service, it is expected that the burden on real estate management companies in guiding residents to consultation services and handling inquiries regarding neighborhood disputes will be reduced.

[Future prospects]
　Through this partnership, GMO ReTech and Vanguard Smith will support the creation of an environment where residents can live with peace of mind, and help improve the operational efficiency of real estate management companies.
　We will continue to leverage the services and expertise of both companies to improve the convenience of handling neighborhood disputes in the real estate rental sector.
