Underdog Tech Stack
Fantasy sports platform with three games and real-money tournaments
Underdog operates three in-house fantasy sports games and runs large-scale real-money contests (including a $15M NFL tournament). The tech stack reveals a mobile-first, data-intensive operation: native iOS and Android apps built in Swift/Kotlin with real-time analytics (Datadog, Amplitude), a substantial data platform (Kafka, Flink, Spark, dbt, Looker), and ML infrastructure (SageMaker, Vertex AI, Kubeflow). Current hiring and project focus signals regulatory maturity — finance and ops roles dominate new hires, and active projects center on financial compliance, audit readiness, and record retention, indicating a shift toward institutional-grade operations as the business scales.
