Banking Ciudad de México, Ciudad de México 501–1,000 employees Founded 2019 Privately Held

Stori operates a fintech credit platform targeting 400 million underbanked consumers across Latin America, with over 2 million applicants since launch in Mexico. The tech stack—Go, Python, AWS (ECS, EKS, Fargate, Lambda, Step Functions), Snowflake, Databricks, TensorFlow, PyTorch—reflects a data-intensive, ML-forward infrastructure designed for real-time decisioning and fraud detection. Active projects in backend streaming, vulnerability scanning, and AML automation signal heavy investment in risk and compliance, while pain points around scaling ML infrastructure and production monitoring suggest the company is hitting operational inflection points common to high-volume fintech platforms.
