What Joint Crew does

JOINT CREW Inc. (株式会社JOINT CREW) is a Tokyo-based Japanese IT company founded in March 2015 that operates two business segments: Systems Development Services and BabyTech. The Systems Development segment delivers custom web, mobile, and cloud-native applications for enterprise and government clients using React, Vue.js, TypeScript, Go, PHP/Laravel, and AWS/Azure/GCP infrastructure, with a 90% fully-remote delivery model supported by AWS Select Tier Consulting Partner credentials and five offices across Japan (Tokyo, Osaka, Hyogo, Nagaoka, Sado).

The BabyTech segment develops and operates proprietary web products for Japan's childcare and education sectors. くれいしゃ (Kureishu), launched December 2021, is a sick-child and post-illness childcare facility search and reservation platform with a management interface for facility operators. きょうの給食 (Kyō no Kyūshoku), released in beta June 2024, is an allergy-specialized school meal DX web application piloted in Kimitsu City, Chiba. The company also offers 病児保育立ち上げコンサルティング (sick-child childcare startup consulting) covering administrative applications, interior design, and staff training.

JOINT CREW generates revenue through project-based professional services (custom development, cloud migration, DX consulting), managed cloud services, and recurring subscription fees from BabyTech products. In April 2026, the company co-launched the Pocotech consortium with Anwall and Jitte to provide one-stop IT/IoT/AI development from planning through mass production, extending its addressable market into hardware-adjacent product development. Most recently disclosed revenue is ¥1.64 billion for the 11th fiscal period, and the company remains privately held under founder/CEO 村越 了.
