株式会社FOLIO Tech Stack

AI-powered robo-advisor and wealth management platform for retail and institutional investors

Financial Services 千代田区, 東京都 51–200 employees Founded 2015 Public Company

FOLIO is a Tokyo-based online brokerage running a polyglot backend (Scala, Java, Go) on AWS and GCP with Kubernetes orchestration, Redshift analytics, and observability via Datadog. The engineering-heavy hiring mix (11 engineers, 2 data) skews toward backend and microservices work—reflected in active projects around API development, monitoring improvements, and a data utilization roadmap. Pain points cluster around accelerating development velocity and building out internal data infrastructure, suggesting infrastructure maturity is a current constraint.
