INTACTIS Inc. is a Tokyo-based company specializing in WordPress production and operational support. It is not positioned as a general-purpose SaaS developer tool, but rather as a provider of custom WordPress development, data integration, and maintenance services for companies and organizations. Its work covers corporate websites, membership sites, e-commerce, event reservation sites, multilingual sites, internal product catalogs, and more, with an emphasis on using WordPress as a “growth engine.”
Based on the available content, INTACTIS’s strength lies in deep WordPress customization: original themes, proprietary plugins, customized admin dashboards, easy-to-update editing interfaces built around custom fields, and delivery of client-specific functionality as plugins to reduce the risk of future WordPress updates and rebuilds. Data integration is also a key capability, including integrations between WordPress and CRM/SFA/MA tools, Notion, Zoho CRM, GA4, the OpenAI API, and external database authentication. Its technical blog showcases implementation ideas such as using the ChatGPT API to score inquiry quality and filter sales emails, automatically registering form data through the Notion API, and setting up conditional notifications in Gravity Forms, indicating strong hands-on engineering experience.
Pricing is relatively transparent. Web production is quoted by page, design, coding, and functionality: original themes cost 330,000 yen, API integration starts from 110,000 yen, and feature customization starts from 38,500 yen. Data integration includes an initial setup fee and monthly fees, with one-way synchronization at 11,000 yen per instance per month and two-way synchronization at 16,500 yen per instance per month. Basic WordPress maintenance starts at 33,000 yen per month, making it suitable for clients with clear long-term operational budgets.
The advantages are its vertical focus on WordPress, with case studies covering complex projects such as universities, membership sites, proprietary plugins, and API integrations. Its services, workflow, FAQ, and technical articles are also fairly detailed. The downside is that it is essentially a custom service provider rather than a ready-to-use development platform. Its content is mainly in Japanese, support for CMSs beyond WordPress appears limited, and it is not stated whether its proprietary plugins are open source or available for standalone purchase.
It is suitable for companies, universities, agencies, and design firms in the Japanese market that need complex WordPress CMS development, business system integration, form automation, AI-enhanced site functionality, and long-term maintenance and operations. It is less suitable for users looking for low-code SaaS, a standardized API platform, or a multilingual global delivery team.
The main content does not provide information about access from mainland China, ICP filing, CDN support, or cross-border service availability, so actual accessibility should be marked as unknown.
