EWeLL

What EWeLL does

EWeLL (株式会社eWeLL, ticker 5038) is a Japanese vertical SaaS company founded in Osaka in 2012 and listed on the Tokyo Stock Exchange Growth Market in September 2022. The company exclusively serves Japan's home-visit nursing station market — a fragmented universe of more than 20,000 SMB stations (60% for-profit, 30% medical corporations, 10% NPO/government) — with its flagship cloud product, iBow, the first EMR purpose-built for visiting nursing in Japan. iBow covers nursing records, scheduling, billing preparation, and is tightly integrated with downstream modules: iBow Receipt for automated insurance claims, iBow KINTAI for attendance management, iBow BPO (BPaaS) for outsourced administrative work, and iBow e-Campus for statutory training. As of 2025, the platform supports 54,000 nurses, manages 1.4 million+ visits per month, has accumulated 100 million+ visit records, and serves 3,501 contracted stations (18.7% national share).

The technology layer is anchored by a vertical data flywheel: each visit captured in iBow feeds the company's AI roadmap, which includes generative AI care-plan generation (launched April 2024, Japan's first), AI monthly report drafting (October 2024), and AI visit schedule and route optimization (GA July 2026). The Care Log (けあログっと) platform extends the product into a regional coordination network connecting hospitals, care managers, and nursing stations for discharge matching. EWeLL maintains ISO 27001 certification (JQA-IM1489 since February 2018) and compliance with the Ministry of Health, Labour and Welfare's Medical Information System Security Guidelines (3rd edition, 2nd guide line).

EWeLL monetizes primarily through per-visit SaaS subscriptions (¥100/visit), a 5% take rate on insurance claims for BPaaS (¥100,000/month minimum), usage-based AI service fees (¥20/visit), annual statutory training subscriptions (¥180,000/station/year), and ancillary services including factoring, e-commerce marketplace fees, and device leasing. Direct sales (field and inside) target SMB and mid-market stations, supplemented by customer seminars, industry exhibitions (International Modern Hospital Show, CareTEX, Medical Japan), and major Japanese media coverage. FY2025 revenue was ¥3,392 million with a 45.3% operating margin, 0.17% revenue churn, and a cumulative 211.6% revenue increase since the 2022 IPO.

Scale indicators16 records

Recent moves10 records

Expansion highlights6 records

Broad incumbents

• PHC Holdings: PHC Holdings (TSE: 6523) is a healthcare IT and medical device conglomerate with broad reach across clinical workflows in Japan, comparable to EWeLL as a healthcare software/data infrastructure provider but operating at a much larger scale across different segments.
• Software Service: Software Service is a major Japanese hospital EMR vendor with deep penetration in inpatient electronic medical records, representing the broader incumbent category that could expand into the home-visit nursing niche.
• M3, Inc. M3 (TSE: 2413) operates a broad medical professional platform including MR Japan, medical site, and clinical trial services — a much larger incumbent with adjacent healthcare IT exposure but no specialized home-visit nursing EMR.

Direct peers

• Medley: Medley (TSE: 3660) operates a digital platform that includes a home-visit nursing matching service (Medley Visit) and broader healthcare platform, overlapping directly with EWeLL's home-visit nursing focus and addressing the same SMB station segment in Japan.
• Y's System (ワイズマン): Y's System is a long-standing Japanese care software vendor with 介護ソフト products covering visiting nursing stations, making it a direct competitor to EWeLL in the same end-customer base.
• Kanamic Network: Kanamic Network (TSE: 3939) provides cloud SaaS for medical, nursing, and welfare facilities in Japan, including functionality for visiting nursing stations that competes head-to-head with EWeLL's iBow platform.

Emerging players

• Ubie: Ubie is a Japanese medical AI company building AI-powered symptom checking and clinical workflow tools for healthcare providers; while it overlaps with EWeLL on AI-in-healthcare positioning, it does not directly compete in the home-visit nursing EMR space today.

Others

• Benefit One (Dental/Healthcare IT arm): Benefit One and other Japanese corporate welfare/HR platforms touch healthcare benefits administration and employee support that can be thematically adjacent to EWeLL's e-Campus and HR modules, but do not compete in home-visit nursing EMR.
