What GMO Reserve Plus does

GMO Reserve Plus Co., Ltd. (GMOリザーブプラス株式会社) is a Japanese vertical SaaS company that develops cloud-based reservation management and clinic operation systems for medical clinics, dental practices, and animal hospitals. Founded in April 2016 in Shibuya, Tokyo, the company operates a portfolio of branded products: Medical Revolution byGMO for general medical clinics, Dentry byGMO for dental practices, Animary byGMO for veterinary hospitals (launched February 2025), and the Omatome Seikyuken byGMO smartphone app that consolidates appointment cards across clinics. The platform unifies web and in-clinic reservations, tracks patient status, handles CRM functions, and integrates with electronic medical record systems, payment services (fincode byGMO, stera terminal), and communications channels such as LINE. A reported outcome is a dental cancellation rate reduction from 18% to 3.5% at reference clinics using Dentry byGMO.

The underlying technology is built primarily in PHP, C#, and JavaScript/Node.js with MySQL databases, deployed on Microsoft Azure and Google Cloud Platform with a weekly release cadence. Newer features leverage AWS serverless infrastructure (Lambda, API Gateway, DynamoDB) for real-time patient call display, and the company is actively building AI capabilities including AI-Board (medical management analytics launched May 2025), deep-learning-based cancellation rate prediction, and AI-driven patient outreach via LINE Pinpoint Delivery. The company holds a MEDIS-DC recognized Privacy Mark certification, a baseline credential for handling personal medical data in Japan.

GMO Reserve Plus generates revenue through annual SaaS subscriptions to its reservation management systems, sold via quote-based pricing rather than published tiers. Go-to-market combines a direct field sales team handling inbound inquiries and partner sales with medical device distributors, EMR vendors, and medical consulting firms, supplemented by a product-led DX Starter Plan introduced in November 2023 for smaller clinics and SEO-driven inbound demand on dedicated product websites. As of January 2025, active clinic accounts exceeded 2,000. Since October 2025, the company is controlled by GMO Payment Gateway (GMO-PG), a consolidated subsidiary of the publicly listed GMO Internet Group (TSE Prime: 9449), following a capital increase that raised capital and capital reserves to 846M JPY. Headcount stood at 67 as of October 2025.

Specialized variants include Dentry byGMO for dental practices (with proven cancellation reduction from 18% to 3.5%) and Animary byGMO for veterinary hospitals featuring multi-pet booking, vaccine management, and LINE callouts.

Direct peers

• Medley (メドレー): Japan-headquartered healthcare SaaS company operating CLINICS (online medical care) and JobMedley (medical professional recruitment). It directly competes with GMO Reserve Plus in the Japanese clinic digital workflow and patient-facing booking space, with overlapping target customers (clinics) and similar SaaS subscription economics.
• MICIN (マイシン): Operates Curon (online medical consultation) and other digital health solutions for Japanese clinics and hospitals. It is a direct competitor in the Japanese clinic digital infrastructure layer, with comparable business model (B2B SaaS to medical institutions) and overlapping product positioning in online consultation and patient scheduling.

Emerging players

• Doctorbook: Japanese dental-vertical SaaS provider focused on dental clinic management and digital transformation. Direct overlap with Dentry byGMO on dental clinic workflow (appointment, recall, CRM), but smaller scale and narrower dental-only focus.
• Yokosho (横松): Japanese vendor of reservation/management systems for dental clinics (Yokosho system is widely installed in Japanese dental practices). Comparable to Dentry byGMO in customer segment, product category, and Japan-only deployment, with a longer-tenured installed base.
• Phybbit (フィビット): Japanese SaaS company offering reservation systems to salons, clinics, and wellness providers. The product category (appointment reservation SaaS in Japan) and SMB/mid-market customer overlay position it as a cross-vertical reservation SaaS peer, though medical is a partial, not core, segment.
• DearOne / MEDISOL Group: Japanese cloud-based electronic medical record and clinic operations vendors targeting small clinics. Directly comparable in Japan-only clinic SaaS positioning, customer segment (small/medium clinics), and cloud-native architecture, with overlap in scheduling and patient management modules.

Broad incumbents

• Nihon Denshi Kaihatsu (NED / 日本電子開発): Provides reservation and patient management systems for medical clinics in Japan, broadly comparable to Medical Revolution byGMO. Larger and more established player with a broader hospital/clinic portfolio, but typically positioned as a more legacy on-premise system rather than a cloud-native vertical SaaS.
• Reserva (リーサ): Smart reservation system widely used by Japanese SMBs across many verticals including medical/beauty/health. It is a horizontal Japanese reservation platform with partial overlap in clinic customers, though it is a less specialized healthcare SaaS than GMO Reserve Plus.
• Sakura (さくら): Provides electronic medical record and clinic management systems across Japan, including scheduling, receipt, and patient management. Comparable in target customer (Japanese clinics) and broad clinic operations workflow, though typically on-premise-leaning where GMO Reserve Plus is cloud-native.

Regional players

• LINE Healthcare (LINE ヘルスケア): LINE's healthcare arm providing online consultation and digital health services in Japan with strong LINE messaging integration. Comparable in Japan-only clinic digital infrastructure and LINE-based patient engagement, complementary to GMO Reserve Plus's LINE-integrated features.
