Enterprise-only platform: Glean is designed exclusively for enterprise deployments. It requires IT involvement for setup and connects across your company's entire tool stack. Its $200M ARR from blue-chip enterprise customers validates genuine, measurable productivity ROI — but small businesses and budget-constrained teams should look elsewhere.
Glean is the leading enterprise AI work assistant that connects to all your company's apps — Slack, Google Drive, Jira, Salesforce, GitHub, Confluence, and 100+ others — providing a unified AI layer for knowledge discovery, search, and intelligent automation across your entire organization.
What started as a smart enterprise search tool has evolved into a full AI intelligence platform. With $200M ARR and a $7.2B valuation from its Series F round, Glean is now one of the most valuable enterprise AI companies. In 2026, it launched 200+ new features and introduced Glean Agents — AI agents that can autonomously complete complex multi-step work tasks.
Glean's core value proposition is eliminating information silos. Instead of employees spending hours searching across multiple apps, Glean creates a single AI-powered entry point to all company knowledge. Answers are grounded in your actual company data with source citations, making it reliable for sensitive enterprise use cases.
Search across 100+ connected apps simultaneously. Find any document, conversation, code, or data in seconds regardless of where it lives.
New in 2026 — AI agents that autonomously complete multi-step tasks: drafting emails, creating reports, scheduling, and answering complex questions from multiple sources.
Get direct answers to questions with exact citations to source documents. Reliable for enterprise use where accuracy is non-negotiable — no hallucinations.
AI automatically surfaces relevant information based on your current context and role — proactively reduces knowledge gaps across your team.
Find experts within your organization. Know who to ask based on their work, documents they've created, and areas of expertise across your company.
Native integrations with Slack, Google Workspace, Microsoft 365, Jira, Salesforce, GitHub, Confluence, Notion, Box, Dropbox, and 90+ more tools.
| Plan | Price | Best For |
|---|---|---|
| Enterprise | Custom pricing | Large enterprises — typically $20–40/user/month for mid-market deployments. Contact sales for exact pricing based on seat count and integrations. |
Glean pricing is exclusively enterprise and customized per deployment. Factors include number of seats, integrations connected, and support tier. Most mid-market deployments run $20–40/user/month. Large enterprise contracts vary significantly. Contact Glean's sales team for a quote.
Microsoft Copilot is deeply integrated with Office 365 but limited to the Microsoft ecosystem. Glean connects to 100+ apps regardless of vendor, making it superior for organizations using diverse toolsets. If your organization runs exclusively on Microsoft, Copilot may suffice — but mixed-stack enterprises will find Glean significantly more capable.
Notion AI works within Notion's environment. Glean spans your entire company's tool stack. For knowledge management beyond Notion, Glean is significantly more powerful. Notion AI is ideal for teams already centralized in Notion; Glean serves organizations that need cross-platform intelligence.
Glean is one of the most important enterprise AI platforms available. Its $200M ARR from blue-chip enterprise customers reflects genuine, measurable productivity value. The addition of Glean Agents transforms it from a search/retrieval tool into an autonomous work intelligence platform.
For large enterprises with complex, fragmented tool environments, Glean delivers ROI that justifies its premium pricing. The barrier to entry is the enterprise-only pricing and setup investment, but organizations that deploy Glean typically see significant productivity gains in knowledge work within weeks.
Recommended for: Enterprises with 500+ employees, complex multi-tool environments, and knowledge-intensive workflows where finding information is a daily friction point.
Not recommended for: Small businesses, startups, or teams primarily using a single platform like Microsoft 365 or Google Workspace.
