Enterprise Work AI platform: permission-aware search, assistant, and agents
Last reviewed 2026-06-18
Glean is an enterprise Work AI platform that indexes a company's data across 100+ SaaS apps into a permissions-aware knowledge graph, then layers enterprise search, a RAG-based assistant that answers with citations, and an agent builder for multi-step workflows. It is built for mid-to-large enterprises that want a single governed AI layer over scattered internal knowledge, enforcing permissions so users only see what they are already allowed to see. Its autonomy is mixed and leans supervised. Search and the Assistant are clearly assistant-grade; the Agents are supervised agents (multi-step workflows wrapped in governance, certification, and human-in-the-loop controls). Glean markets autonomous agents, but its own public materials emphasize oversight and permission enforcement, so the autonomous claim is supervised in practice. Its real differentiator is the unified, permission-enforced index, not a proprietary model: Glean is model-agnostic.
What it can do
Search across company knowledge
AssistantUnified, permission-enforced enterprise search across 100+ connected apps.
sourceAnswer questions with cited insights (Glean Assistant)
AssistantA RAG assistant that searches company tools and the web, reasons in multiple steps, and returns grounded answers with citations.
sourceBuild and run multi-step agents (Agent Builder)
SupervisedA no-code, natural-language builder for reasoning agents and workflows grounded in enterprise context, with an orchestration layer to route tasks between agents.
sourceConnect external tools via MCP
SupervisedActs as both an MCP host (so the Assistant and Agents can invoke external tools) and a remote MCP server (so other LLMs pull Glean's enterprise context), all admin-governed.
sourceGovern agents at enterprise scale
CopilotDeploys, shares, certifies, and monitors many agents with adoption, error, and ROI dashboards as a human admin control plane.

Strengths
- +Best-in-class unified, permission-enforced index across many apps with citation-grounded answers
- +Genuinely model-agnostic and open: MCP host plus server, bring-your-own model, and on-prem deployment
- +One governed platform spanning search, assistant, and agents with built-in certification and monitoring
Limitations
- −Opaque, expensive pricing with high seat minimums and add-on fees; reported fully-loaded deployments run into the hundreds of thousands
- −The autonomous-agents marketing outpaces demonstrated autonomy; in practice agents are supervised
- −Value depends heavily on connector coverage and clean, well-permissioned source data
Overview
Glean is an enterprise Work AI platform. It indexes data across 100+ SaaS apps into a permissions-aware knowledge graph, then offers enterprise search, a cited RAG assistant, and an agent builder.
What it does
Search returns permission-enforced results across connected apps. The Assistant answers questions with citations from company tools and the web. Agent Builder lets teams create no-code reasoning agents and workflows grounded in enterprise context, with orchestration and governance (certification, monitoring, ROI dashboards). Glean is both an MCP host and a remote MCP server.
Integrations & setup
100+ connectors (Slack, Google Workspace, Jira, Salesforce, Confluence, ServiceNow, GitHub, Box), third-party tools via MCP, and on-prem deployment options. Model-agnostic with no proprietary foundation model.
Pricing
Per-seat, annual, quote-based with no official public figure; reported third-party estimates start around $50/user/month with a roughly 100-seat minimum, scaling well into six figures.
Best for / not for
Best for mid-to-large enterprises that want one governed AI layer over scattered internal knowledge with permission enforcement. Less suited to small teams (cost and seat minimums) or buyers expecting fully autonomous agents.
Traction
Reported $150M Series F at a $7.2B valuation (TechCrunch, June 2025), with ARR surpassing $100M for the fiscal year ended January 2025 per the company; later figures are secondary estimates.
Alternatives
Microsoft Copilot is the closest enterprise analog; Notion AI overlaps for workspace knowledge; Perplexity offers cited research at the individual level.

FAQ
Is Glean an autonomous agent platform?+
Partly. Its search and Assistant are assistant-grade, and its Agents are supervised agents: multi-step workflows wrapped in governance, certification, and human-in-the-loop controls. Glean markets autonomous agents, but its own materials emphasize oversight, so treat the autonomy as supervised in practice.
Does Glean enforce data permissions?+
Yes. Its index is permission-aware, so users only see content they are already allowed to access, and that enforcement carries through search, the Assistant, and agents.
