Tech stack
  • Neo4j
    Neo4j is the world's leading native graph database, purpose-built for high-performance management and traversal of connected data.
    Neo4j is the leading native graph database, leveraging the Property Graph Model (nodes, relationships, properties) for data storage and retrieval . It is an ACID-compliant, high-performance platform designed for managing highly connected data at scale (billions of nodes) . Queries execute using the declarative Cypher query language, which simplifies complex traversals that would cripple relational systems with numerous JOINs . This architecture delivers orders of magnitude performance improvements (often minutes to milliseconds) for relationship-based queries . Major use cases include fraud detection, recommendation engines, and knowledge graphs for AI, trusted by 84 of the Fortune 100 .
  • Graph database
    Graph databases are NoSQL systems that use nodes, edges, and properties to model and store data, prioritizing relationships for high-speed traversal and complex query performance.
    This technology is a specialized database platform: it stores data not in rigid tables, but as a network of nodes (entities) and edges (relationships). This structure makes relationships first-class citizens, enabling ultra-fast queries that would require dozens of expensive JOIN operations in a relational system (SQL). For example, a graph database like Neo4j can traverse billions of connections in milliseconds. It’s the essential tool for use cases where connections matter most: social networks, real-time fraud detection, and complex recommendation engines. You're modeling the real world directly, not forcing it into a tabular schema.
  • GenAI
    GenAI is the class of artificial intelligence (AI) that creates novel content—text, code, images, video—from simple user prompts, driven by deep learning models.
    This technology is a major shift: it moves AI from analysis to creation. Generative AI relies on sophisticated deep learning models (like Large Language Models, or LLMs) that identify patterns in massive datasets, then generate original outputs based on a natural language request. The public launch of ChatGPT in 2022 accelerated adoption; now, over one-third of organizations report using GenAI regularly in at least one business function (McKinsey). Analysts project over 80% of organizations will deploy GenAI applications or APIs by 2026 (Gartner), focusing on productivity gains in areas like code generation and dynamic content personalization.
  • GraphRAG
    GraphRAG integrates knowledge graphs with Retrieval-Augmented Generation (RAG) to enable multi-hop reasoning and deliver context-rich, verifiable LLM responses.
    GraphRAG is a superior RAG architecture: it moves beyond simple vector-based semantic search. The system constructs a knowledge graph (KG) from unstructured data, extracting entities and relationships (nodes and edges). This structure allows the Large Language Model (LLM) to perform complex, multi-hop reasoning, a task where baseline RAG systems often fail. By leveraging the KG's relational context instead of isolated text chunks, GraphRAG significantly improves answer accuracy, reduces hallucination, and provides a clear, traceable provenance for the generated response. It is a critical upgrade for enterprise GenAI applications demanding high-trust, explainable results.

    This is a specialized, high-impact application of graph intelligence (GraphRAG): HopperGraph leverages Neo4j AuraDB to analyze a massive dataset (234,000 nodes, 1.5 million relationships) from Reddit. The system applies natural language processing and community detection algorithms to identify which fan communities have historically predicted storylines most accurately. AI 'Stranger Agents' then guide users through the data, connecting character backstories and narrative arcs to visualize plot possibilities for the series finale.
