Emil Eifrem
Profile
CEO at Neo4j.
Biography
Emil Eifrem is the co-founder and CEO of Neo4j, the graph database and analytics leader that enabled investigative journalists to crack the Panama Papers leak, NASA to get to Mars two years faster, power discoveries in biodiversity and genomics sampling, cancer research, fraud detection, scientific research, and serve thousands of organizations worldwide including 75 of the Fortune 100. Graph uniquely organizes data in the same way that the human brain does in expressing the complex relationships, context and connections between data as data itself. By uncovering the web of relationships underlying our interconnected world, graph enables organizations to dynamically predict what happens when these relationships change and why.
Emil created the category of graph databases and has devoted his professional life to building, innovating, and evangelizing graphs. Graph has since become the fastest-growing database category over the past decade. Neo4j’s series F funding round was also the largest in database history, valuing the company at more than $2B. Gartner predicts that by 2025, graph technologies will be used in 80% of data and analytics innovations — up from 10% in 2021 — facilitating rapid decision-making across the enterprise. Neo4j has become essential for enterprise GenAI in reducing hallucinations with knowledge graphs, serving as long-term memory for LLMs, and dramatically improving GenAI outcome accuracy, explainability, and transparency. Neo4j is headquartered in Silicon Valley. Emil is based in Sweden.
