株式会社ココペリ│KOKOPELLI Inc. Tech Stack

Fintech platform connecting regional banks to SMB growth services

Software Development 千代田区, 東京都 11–50 employees Founded 2007 Privately Held

Kokopelli operates Big Advance, a fintech platform where financial institutions collaborate to support small and mid-market business growth across Japan. The tech stack—PHP, Go, Java, Python layered on AWS with PostgreSQL and Redshift—reflects a mature, polyglot backend handling transaction and data workloads. Active projects signal heavy platform engineering work (microservices decomposition, reliability improvement, platformization), while pain points reveal a core tension: strong product-market fit within their bank partner network but friction scaling sales capacity and reaching SMBs directly.
