What RitaWorks does
RitaWorks Inc. (リタワークス株式会社) is a privately held Osaka-based software company that builds specialized content management systems (CMS) and digital infrastructure for Japan's hospital and nonprofit sectors. Founded in 2008 as MediaSuite Co., Ltd. and rebranded to RitaWorks in 2015, the company operates three core SaaS products: mirahos (hospital website CMS, 450 hospital customers across all 47 prefectures since 2010), nuweb (NPO website CMS, 200+ projects since 2016), and proppy (web production project management tool developed from 1,000+ site builds). The company has also incubated and spun off two operating subsidiaries — Congrant (digital NPO fundraising platform, spun off 2020) and Medigle (regional medical coordination tool, spun off 2022) — and acquired the Kifufu donation flyer service from Gahaha Inc. in December 2025 to extend into offline fundraising channels.
The business model is primarily subscription-based recurring revenue across its CMS products, augmented by professional services revenue (Kifufu production), transaction fees flowing through the Congrant group company, and selective corporate investments such as SUNDA (Africa water access). RitaWorks goes to market through direct website inquiry sales, industry events (FRJ Fundraising Japan, SOCIALSHIP grant programs), email newsletters segmented by vertical, and community-building through rita-cinema social movie screenings co-organized with Panasonic Center Osaka. The 62-person organization (54 FTE + 8 contract, May 2024) is led by Representative Director Yuta Nakagawa following a 2022 leadership transition from founder Masataka Sato.
The company has funded growth through two disclosed dividend-type preferred share placements (Social Business Investment 2021 and 2023) targeted at individual investors, with registered capital of approximately ¥84.4M. RitaWorks holds no disclosed institutional venture or private equity backing, consistent with its self-described positioning as a social business pursuing the 2030 vision of 'a society where many people feel tomorrow will be better.'

RitaWorks competitors and assessment
Company assessmentDirect peers
- Jimdo: Jimdo is a Germany-based DIY website builder with strong presence in Japan (Jimdo Japan). It offers website creation for small businesses and nonprofits, directly competing with RitaWorks' nuweb and offering similar subscription-based CMS services with comparable target customers.
- Asana: Asana is a leading work and project management platform with a Japan presence. Directly comparable to RitaWorks' Proppy tool — both target creative agencies and project teams needing workflow management, offered via subscription SaaS with similar feature focus on task tracking and project coordination.
- Trello (Atlassian): Trello is a widely-used visual project management tool from Atlassian, with significant Japanese market adoption. Comparable to Proppy as a project management SaaS for teams, though more horizontal/generalist versus Proppy's web-production specialization.
- DonorPerfect: DonorPerfect is a long-established US-based nonprofit donor management and fundraising software platform serving thousands of NPOs. Directly comparable to RitaWorks' nuweb and Congra offerings in serving NPO fundraising needs via subscription SaaS with similar focus on donor databases and donation processing.
- Donorbox: Donorbox is a US-based donation platform specifically built for nonprofits, offering online fundraising, recurring donations, and donor management. Comparable to RitaWorks' nuweb and group company Congra, focused on the same NPO fundraising use case through subscription-based SaaS.
- Network for Good: Network for Good is a US-based nonprofit fundraising and donor management software platform serving NPOs with donation processing, CRM, and campaign tools. Directly comparable to RitaWorks' nuweb/Congra ecosystem in target market (NPOs), business model (SaaS subscriptions), and core use case (fundraising enablement).
Emerging players
- Webflow: Webflow is a visual website builder that has expanded into Japan and serves small businesses, agencies, and increasingly verticals like nonprofits. Comparable to RitaWorks' CMS products in core functionality (visual website creation), with growing Japan presence and a more modern developer-friendly positioning.
Broad incumbents
- Squarespace: Squarespace is a major website builder with strong design positioning and a presence in Japan. It serves small businesses, creatives, and nonprofits through subscription-based website building, competing with RitaWorks' CMS offerings on the broader site-builder market though without RitaWorks' deep vertical specialization.
- Salesforce.org (Nonprofit Cloud): Salesforce.org is the nonprofit arm of Salesforce, providing CRM and fundraising solutions to NPOs globally including in Japan. A broad incumbent with overlapping capabilities to RitaWorks' NPO ecosystem (nuweb + Congra), serving larger enterprise nonprofits with integrated fundraising, donor management, and engagement tools.
- Wix.com: Wix is the global leader in DIY website building, operating in Japan through Wix.com.jp. While broader than RitaWorks' vertical-specific CMS approach, Wix increasingly offers vertical templates including healthcare and nonprofit categories that overlap with RitaWorks' hospital and NPO segments.
