Financial Services Musashino, Tokyo 51–200 employees Founded 2005 Privately Held

KOMOJU operates a payment platform designed for merchants entering Japan and Southeast Asia, where local payment methods and regulatory complexity create friction. The tech stack—Kotlin, Java, Android, AWS, Salesforce, HubSpot—reflects a fintech infrastructure built for scale, with active investment in mobile apps and POS systems. Current hiring velocity (11 roles in 30 days, mostly support and senior engineers) combined with projects around sales process improvement, customer success team launch, and application security suggests the company is transitioning from developer-led adoption toward managed revenue operations and operational maturity.
