Glean is an AI-powered enterprise search and workplace assistant that builds a knowledge graph of an organization's internal data, people, and interactions to generate highly personalized, permissions-aware answers. Unlike general-purpose AI tools, Glean understands company context and combines it with large language models to solve real business problems. The platform has evolved from enterprise search to a general-purpose work assistant with an agent platform for automating workplace tasks. It serves enterprise organizations looking to unlock knowledge trapped across dispersed data sources.

Problem solved

Employees struggle to find answers within their own organization despite having access to the data, wasting time searching across multiple systems when critical information is locked in enterprise data.

Target customer

Fortune 500 and large mid-market enterprises (1000+ employees) across NA, Europe, and APAC requiring secure, permissions-aware AI search and knowledge discovery.

Competitors

ChatGPT / OpenAI

ChatGPT lacks awareness of internal company data; Glean contextualizes responses using proprietary knowledge graphs of enterprise information.

Microsoft Copilot for Microsoft 365

Glean provides broader enterprise data integration across any source with more sophisticated permissions awareness; Microsoft's solution is tightly integrated with Microsoft products.

Google Cloud Search

Glean offers AI-powered answers with knowledge graph personalization; Google Cloud Search is primarily traditional search without advanced AI reasoning.

Atlassian Compass

Glean spans all enterprise data sources; Compass focuses on component discovery and management within development ecosystems.

Why this matters: Glean represents the emerging category of context-aware enterprise AI that bridges the gap between general-purpose LLMs and real business problems. With $765M in funding, $200M+ ARR, and a $7.2B valuation as of June 2025, Glean demonstrates strong market validation for AI-powered knowledge discovery in the enterprise, and its agent platform expansion signals the next wave of workplace automation.

Best for: Large enterprises with complex, distributed knowledge bases across multiple systems who need employees to quickly find accurate, contextual answers while maintaining security and permissions governance.
