Have you ever experienced this? You clearly recall your team reached a key conclusion during a discussion, or you spotted critical data in a certain document — yet you simply cannot track it down anywhere.
You scroll through endless Slack chat history, open a dozen tabs in Google Drive, spend ages searching Jira tickets, and eventually have to message a colleague: “Hey, do you remember where we stored that information we talked about last time?” By the time you finish going back and forth, more than half an hour has slipped away; the original issue remains unresolved, and you’re already worn out.
This isn’t your fault. It’s a widespread pain point plaguing modern corporate workflows: information is locked away across dozens of disjointed tools, with no single unified entry point to locate everything.
This is exactly the pain point Glean was built to solve.
What Is Glean?
Glean is an enterprise-focused AI search and workplace platform. Its core objective is straightforward: unify all information scattered across your company’s disparate tools in one central hub, so you can find exact answers with a single natural-language query.
You can think of it as an internal Google for your company. What makes it far smarter than consumer search engines, however, is its built-in awareness of every employee’s role, data access permissions, and contextual links between pieces of information. All search results returned are strictly limited to content you are authorized to view, and ranked by relevance to your daily work context.
Core Capabilities
Glean’s product suite has evolved through three successive stages: standalone search, conversational AI assistant, and autonomous AI agents. Its full offering now covers three core layers:
1. Glean Search: Search every corner of your organization
It connects to over 100 third-party SaaS tools via dedicated connectors, including Slack, Google Drive, Jira, Confluence, Salesforce, Microsoft Teams, and more. Simply type a natural-language question into the search bar, and it will pull consolidated answers from all integrated platforms.
Crucially, all search results respect user access permissions. Documents you lack authorization to view will never appear in your result list.
2. Glean Assistant: Beyond search — conversational research & content generation
The Assistant layer unifies search and chat workflows. You can follow up and dig deeper just like chatting with a coworker, and it will stitch together data from multiple disparate sources to deliver integrated conclusions.
It can even generate visual graphics directly within the conversation. For instance, if you’re drafting a sales deck, the Assistant can instantly render charts highlighting key performance highlights and risk factors, ready to be dragged straight into your PowerPoint slides — no tool switching required at any stage.
3. Glean Agents: Let AI automate repetitive work on your behalf
This is Glean’s newest feature, the closest functionality yet to having an AI handle your daily workload independently. You can build custom AI agents using plain natural language to automate repetitive routine tasks.
For example, a product manager could instruct Glean: “Extract user feedback from this document, create corresponding Jira tickets with attached screenshots and source links, then schedule a review meeting.” Tasks that once took multiple hours can now complete in under a minute.
What Powers Its Core Competitiveness?
Glean’s competitive edge stems from six years of investment in foundational underlying technology.
Its backbone consists of two core components: the Enterprise Knowledge Graph and Agentic Engine 2. Beyond merely indexing documents, this knowledge graph maps contextual relationships between people and content: who is working on which projects, which documents are interrelated, and how information flows across teams.
Built on top sits a Model Abstraction Layer. Enterprises avoid vendor lock-in tied to any single LLM provider, with full freedom to switch between or combine models including ChatGPT, Gemini, and Claude. Additionally, every generated output links back to original source documents with line-by-line citations, eliminating AI hallucinations entirely.
Market Performance
Founded in 2019 by Arvind Jain, a former Google Search engineer, Glean reached a valuation of $7.2 billion by 2026, with annual recurring revenue (ARR) exceeding $200 million.
Its customer roster includes well-known brands such as Instacart, Pinterest, Reddit, Duolingo, Grammarly, Sony, alongside multiple Fortune 500 corporations. In 2025, Glean was named an Emerging Leader in Generative AI Knowledge Management by Gartner. A Forrester analysis found businesses deploying Glean achieved a 141% return on investment within three years.
User Feedback
Across review platforms including TrustRadius, users consistently highlight that its core search functionality is a game-changer for workplace productivity. One user shared it “made it effortless to locate internal company information and drastically elevated my performance as a talent recruiter.” Engineers also noted it “streamlines access to work assets, especially resources not optimized for mobile viewing.”
That said, some feedback points out room for improvement within its conversational AI layer, with responses occasionally lacking full precision.
Ideal User Profile
Glean is built for mid-to-large enterprises. If your organization leverages a stack of disjointed tools including Slack, Google Workspace, Jira, Confluence, Salesforce, leaving information fragmented across siloed systems and employees wasting countless hours hunting for data every day — Glean functions as the foundational knowledge infrastructure your team needs.
It is not a general-purpose AI assistant for individual end users; it is enterprise-grade knowledge infrastructure built for entire organizations.
Closing Thoughts
We spend far too much time searching for information, rather than acting on it. Glean’s core value lies in weaving scattered knowledge trapped across dozens of separate tools into an interconnected knowledge network accessible on demand. As its official documentation puts it: “It acts like a veteran employee who has been with the company since day one, read every document, sat in every team discussion, knows every colleague’s expertise, and stands ready to support you at any time.”
If you’re tired of toggling between dozens of platforms and digging through ancient chat logs to track down critical information, Glean may well be the unified solution you’ve been searching for.
