ClearScore Tech Stack

Credit marketplace connecting millions to financial products via API partnerships

Financial Services London, England 201–500 employees Founded 2015 Privately Held

ClearScore operates a credit marketplace serving 24 million users across five markets, powered by Databricks, Kubernetes, and AWS. The tech stack—SQL, Python, Go, Rust, Node.js, React—reflects a data-heavy consumer platform with both backend throughput and frontend complexity. Active projects (Kubernetes platform evolution, CI/CD pipeline development, AWS cost optimization, fraud prevention) indicate infrastructure maturation and tighter operational controls; the hiring velocity across engineering, product, and data suggests scaling beyond the consumer app into deeper API partner integrations and risk management.

The product is built around user-permissioned data, matching consumers to products algorithmically, and helping financial institution partners optimize conversion, revenue, and risk management.
