What Cuon does

Cuon (株式会社Cuon) is a Tokyo-based private professional services firm specializing in enterprise application development, with primary expertise in Ruby on Rails and complementary stacks including Vue.js, React, Elixir, Flutter, Dart, and Python. Founded in 2016 and operating as a member of TerraSky Group (a Tokyo Stock Exchange Prime-listed cloud integrator), Cuon is structured around three business segments: IT Consulting (competitive-advantage planning and implementation using OSS technologies), EC/Data-Driven Marketing (Salesforce B2C Commerce, Marketing Cloud, Pardot, Tableau, Snowflake integrations), and SRE/DevSecOps (AWS, MuleSoft, Heroku-based continuous delivery and security operations). The firm maintains AWS Partner Network Consulting Partner status, Ruby Association Certified System Integrator Silver, and a dedicated Salesforce Cloud Integration department.

Cuon commercializes five named proprietary solutions layered on top of its services: CWAP (web application platform), CGAS (groupware), ECO (EC optimization), Private AI Appliance (on-premises AI for data-sensitive enterprises), and a Data Lake/DMP offering, alongside a branded 'VibeCoding' agile consulting methodology. The company serves Japanese enterprise clients across DX, e-commerce modernization, Salesforce implementation, and cloud-native infrastructure, with documented case studies in winter sports retail, education publishing, and K–12 administration. Customer reach is concentrated in Japan; revenue and financial statements are not publicly disclosed.

Cuon makes money through project-based professional services engagements delivered via direct enterprise sales and through TerraSky Group's channel network. Pricing is individually negotiated and not publicly disclosed; salary and compensation are determined case-by-case. The firm is actively hiring across engineering, AI, consulting, and project management roles, indicating ongoing organizational buildout. Customer concentration appears elevated given the small employee base and limited publicly named logo set.
