Overview

Glean is the leading AI-powered enterprise search and knowledge management platform, connecting to all of an organization's applications — from Google Workspace and Slack to Salesforce and Jira — to provide employees with instant, personalized answers to any work-related question. Founded by Arvind Jain, a former Google distinguished engineer who led the development of Google Drive, Glean uses a proprietary knowledge graph and large language models to understand not just content but context: who created it, who it is relevant to, and how it relates to other organizational knowledge. The platform has evolved from search into a full AI work assistant that can draft documents, summarize meetings, generate reports, and automate workflows. Glean has achieved remarkable enterprise adoption with hundreds of large customers including companies like Grammarly, Databricks, and Duolingo. The company's net revenue retention exceeds 150%, reflecting strong expansion within existing accounts as more employees adopt the platform.
