Smartnumbers Tech Stack

Cloud-based fraud detection platform for contact centers using real-time call risk analysis

Software Development London 51–200 employees Public Company

Smartnumbers operates a cloud-native fraud-detection platform built on AWS primitives (Lambda, ECS, Fargate, Kinesis, DynamoDB, Redshift, Athena) with a TypeScript/React frontend. The stack reveals a company optimized for real-time streaming workloads — Kinesis and EventBridge handle incoming call signals while DynamoDB and Redshift support both low-latency lookups and batch analytics. Hiring is thin but accelerating across engineering, product, ops, and finance, suggesting growth from product-market fit rather than early-stage exploration.
