OrgInGraphs: FalkorDB-Powered Company Brain with Graph and Vector Intelligence
Graph HacksOct 2026
OrgInGraphs is an AI-powered Company Brain that helps employees discover organizational knowledge without spending days navigating scattered documentation and repeated knowledge-transfer meetings. At its core, FalkorDB powers a connected knowledge graph of people, teams, departments, projects, services, and decisions. Using Cypher queries and graph traversal, OrgInGraphs connects related information to reveal context beyond isolated records. The platform combines graph intelligence with vector-based semantic search. An agent continuously checks for updates from configured sources, processes new information, and uses Hugging Face Transformers with the 'Xenova/all-MiniLM-L6-v2' model to convert content into vector embeddings. These vectors are stored with document chunks as 'RAGChunk' nodes, alongside source metadata, and retrieved through FalkorDB's vector indexing and cosine/HNSW similarity search. The retrieved information is enriched with graph relationships, providing a unified foundation for retrieval-augmented generation (RAG). Built with LangGraph-based workflows, OrgInGraphs processes organizational information and connects it to the existing knowledge graph. Its Company Intelligence Hub, Knowledge Graph, Universal Search, and OrgMind Assistant, Nora, help users explore company records and discover context-aware, evidence-grounded answers with source references. Our goal is to give every new hire easier access to organizational knowledge, people, decisions, and workflows - reducing onboarding friction and time spent searching for context. Core technologies: FalkorDB, Cypher, vector search, Hugging Face Transformers, 'Xenova/all-MiniLM-L6-v2', RAG, LangGraph, Next.js, TypeScript, and Amazon Bedrock. Team Prometheus: Garima, Nikhil, and Mohit.
