FIERTE CORPORATION Tech Stack

Consolidated accounting outsourcing and SaaS migration for Japanese enterprises

Accounting 新宿区, 東京都 501–1,000 employees Founded 2017 Privately Held

FIERTE operates a consolidated accounting and treasury outsourcing business inherited from DIVA, Japan's market-leading consolidated accounting system. The company is actively migrating its legacy on-premises product to cloud infrastructure (AWS, Azure, Kubernetes) while building new SaaS-native products—a dual-track shift evident in both the tech-stack churn (adopting PostgreSQL and Linux, replacing Windows and Oracle) and the project portfolio (cloud migration, DX product for automated financial statements, TMS implementation). Product and engineering teams dominate hiring, signaling investment in platform modernization alongside BPO service delivery.
