Glean
Enterprise Work AI platform unifying AI search, an assistant, and agents over a permission-aware company knowledge graph
Glean is an enterprise Work AI platform that unifies AI search, an assistant, and custom agents over a permission-aware knowledge graph built from 100+ prebuilt connectors (275+ including MCP-based ones). Pricing is contact-sales only; third-party estimates put it near $40 to $50 per user monthly plus an AI add-on, but Glean publishes no official figure. Best for mid-to-large enterprises unifying fragmented knowledge.

What is Glean?
Glean is an enterprise “Work AI” platform that connects a company’s applications — email, documents, chat, tickets, code, and CRM — into a single, permission-aware knowledge graph, then layers AI search, an assistant, and agents on top. Instead of hunting across a dozen disconnected tools, employees ask a question once and Glean retrieves an answer grounded in the organization’s own data, with citations and with each user’s existing access controls enforced. It ships with 100+ prebuilt connectors, and its connectors page cites 275+ integrations when native and MCP-based connectors are counted together, covering common systems like Slack, Google Drive, Jira, Confluence, SharePoint, Salesforce, and GitHub.
Beyond search, Glean Assistant answers work questions in natural language while staying grounded in internal knowledge, with access to a wide range of underlying large language models. An agent-building layer lets teams automate multi-step workflows — onboarding, sales research, support deflection — either no-code or through the developer API. Glean positions itself for compliance-heavy environments, carrying SOC 2 Type II, ISO 27001, ISO 42001, HIPAA, and GDPR certifications alongside full observability over queries, answers, and agent actions. As a company, Glean is well established: it raised a $150M Series F at a $7.2B valuation, and 2026 reporting put its annual recurring revenue near $300M.
Who is it for?
Glean is built for mid-to-large organizations whose knowledge is scattered across many SaaS applications and who need a single, governed way to search and act on it. It is an enterprise-only product with no free tier or self-serve signup, so its value depends on connecting a broad set of company apps — which makes it a poor fit for small teams but a strong one for larger, tool-heavy companies.
- Enterprise IT and knowledge-management leaders who want to unify fragmented company knowledge behind one permission-aware search and assistant layer.
- Regulated industries (finance, healthcare, public sector) that need strict access controls, auditability, and certifications like SOC 2 Type II, HIPAA, and ISO 42001.
- Operations and support teams looking to deflect internal IT and HR help-desk tickets by surfacing existing answers automatically.
- Automation and platform teams who want to build no-code or API-driven AI agents that act across connected systems while respecting permissions.

Pros and cons
| Pros | Cons |
|---|---|
| Broad connector coverage (275+) unifies fragmented enterprise knowledge into one searchable layer | No public pricing — everything is contact-sales, so budgeting and comparison rely on unofficial third-party estimates |
| Permission-aware from day one — respects existing source-app access, strong governance for regulated industries | No self-serve or free tier; enterprise-only with reported ~100-seat minimum contracts |
| Search, assistant, and agent-building in a single platform rather than three separate tools | Indexing and rolling out across many apps is a multi-week to multi-month deployment, not an instant setup |
| Deep security and compliance certifications (SOC 2 Type II, ISO 27001/42001, HIPAA, GDPR) | Value scales with the breadth of connected apps, so small teams rarely justify the cost |

Frequently asked questions
How much does Glean cost?
Glean does not publish pricing; every plan is quoted through sales. Third-party sources estimate roughly $40 to $50 per user per month for the base seat plus an AI add-on, often with a minimum around 100 seats, but these figures are unofficial and unverified by Glean. Treat them as ballpark estimates, not confirmed prices.
Does Glean have a free tier?
No. Glean is an enterprise-only platform with no self-serve signup and no free tier. Evaluation happens through a sales demo and a scoped pilot rather than a public free plan.
How many apps does Glean connect to?
Glean offers 100+ prebuilt connectors, and its connectors page cites 275+ integrations when native and MCP-based connectors are combined — covering tools like Slack, Google Drive, Jira, Confluence, SharePoint, Salesforce, and GitHub.
Does Glean respect user permissions and data security?
Yes. Glean builds a permission-aware knowledge graph that mirrors the access controls of each source application, so users only see results they are already entitled to. It carries SOC 2 Type II, ISO 27001, ISO 42001, HIPAA, and GDPR compliance.
What can Glean's agents do?
Glean includes an agent builder for automating multi-step work such as onboarding flows, sales research, and support deflection. Agents can be created no-code or through the developer API and run grounded in company knowledge with permissions enforced.
How is Glean different from Microsoft Copilot?
Glean is model-agnostic (access to 35+ LLMs) and app-agnostic, indexing across Google Workspace, Microsoft 365, Slack, Atlassian, Salesforce, and more via 275+ connectors. Microsoft Copilot is centered on the Microsoft 365 ecosystem, so Glean tends to fit heterogeneous stacks better.
Is Glean a real, established company?
Yes. Glean raised a $150M Series F at a $7.2B valuation and, according to 2026 reporting, its annual recurring revenue crossed roughly $300M. It is one of the larger independent enterprise AI search vendors.
