株式会社ホワイトプラス Tech Stack

On-demand laundry and house-cleaning marketplace with factory operations

Information Technology & Services 品川区, 東京都 51–200 employees Founded 2009 Privately Held

WhitePlus operates two consumer service platforms—Lenet (on-demand laundry delivery) and Kirehapi (house-cleaning marketplace)—backed by physical cleaning operations. The tech stack is distributed across Laravel, Go, TypeScript, and React, suggesting a multi-service backend architecture; the project list (order optimization, cleaning factory backend, payment systems, pricing calculation) reveals a logistics and operations company masquerading as a software vendor. Leadership-heavy hiring (3 leads, 3 seniors out of 8 open roles) against stated pain points (legacy modernization, technical debt, implementation speed) signals an engineering team rebuilding for scale.

About 株式会社ホワイトプラス

WhitePlus is a Tokyo-based venture founded in 2009 by three IT founders to digitize offline lifestyle services. The company operates two main services: Lenet, an on-demand laundry-delivery platform launched in 2009, and Kirehapi, a house-cleaning service marketplace launched in 2018. Lenet's model combines consumer-facing mobile and web ordering with logistics coordination and in-house cleaning operations; the service extends beyond clothing to bedding, shoes, and storage. Kirehapi connects consumers with vetted cleaning providers through a review-driven matching interface. The organization spans 51–200 employees across engineering, operations, manufacturing, and support functions, operating entirely within Japan.
