Sia Tech Stack

Global consulting firm scaling AI and data science across 19 countries

Business Consulting and Services Paris, Île-de-France 1,001–5,000 employees Partnership

Sia is a 3,000-person consulting group headquartered in Paris, operating across strategy, AI, and management advisory. The stack reveals a dual-layer operation: enterprise platforms (Salesforce, Workday, SAP, Oracle) for delivery and client work, paired with modern data infrastructure (Snowflake, Spark, Kafka, Python, R). Heavy adoption of LLMs (GPT, Claude, Mistral) and RAG alongside internal tool building (Node.js, React, Java) signals Sia is both consuming and productizing generative AI — a departure from pure-play consulting toward AI-native service delivery.
