ONE ZERO BANK Tech Stack

Digital private bank building GenAI compliance and infrastructure automation

Financial Services Tel Aviv-Yafo 201–500 employees Founded 2019 Privately Held

ONE ZERO Bank operates a branchless digital banking platform in Israel with a lean, engineering-forward organizational structure. The tech stack reflects a hybrid-cloud infrastructure backbone (AWS + GCP, Kubernetes, Terraform) paired with JVM-based services (Java, Scala, Spring) and modern frontend tools (React, Next.js). Active adoption of RAG, LangChain, and OpenAI signals a push into GenAI-driven compliance automation — directly addressing their stated pain points around manual compliance processes and model-risk governance. The hiring mix is engineering-heavy (one-third of open roles), concentrated in Israel, with accelerating velocity.
