FDJ UNITED operates a multi-brand gaming and betting platform across Europe, anchored by well-known franchises. The tech stack leans heavily on JVM languages (Java, Scala) and .NET, with messaging infrastructure (Kafka, RabbitMQ, Solace) and polyglot storage (SQL Server, Oracle, PostgreSQL, Couchbase) — a mature, distributed architecture typical of high-transaction platforms. Active adoption of OpenAI and Anthropic signals an emerging focus on AI-driven personalization or chatbot automation, which aligns with visible projects on chatbot rollout and bot-driven customer journeys.
