Reducing Time-to-Insight in Company Financial Data by 90%

SoftwareMill built FinBot, an AI-powered natural language interface to their BigQuery financial data, reducing query time from 15-20 minutes to 10-60 seconds. The system uses a multi-agent architecture with LangChain and LangGraph, featuring specialized agents for query routing, entity resolution, SQL generation, and chart creation. The solution eliminated SQL barriers for non-technical users, saving approximately 2,900 hours annually across the organization by enabling conversational queries like "How much did backend development cost in Q2 2025?" instead of complex SQL. Key technical challenges included ambiguous entity matching (solved with fuzzy matching and confidence scores), temporal query handling (context manager), and performance optimization (caching with Redis).
