Our verdict

Glean suits mid-size and large companies whose knowledge is scattered across many apps and that need search and an AI assistant that respects per-user permissions. The trade-offs are no published pricing, no self-serve plan, and efficiency figures on its site that the vendor reports itself.

Best for: Organisations with thousands of staff spread across tools like Slack, Drive, Jira and Confluence

Skip it if: Small teams or individuals who want public pricing and an instant trial

Pros

  • 275+ connectors to work apps with permission-aware search
  • Lists many certifications: SOC 2 Type II, ISO 27001, ISO 42001, HIPAA
  • Assistant, Agents and developer APIs (Client API, Indexing API, MCP server)

Cons

  • No published price list; sold through sales only
  • Some features, including Agents, multiplayer collaboration and multi-step workflows, are still labelled beta on the product page

Experience & key features

What Glean is

Glean launched in 2019 under CEO Arvind Jain and three co-founders, according to Fortune. Jain spent over a decade as a search engineer at Google and co-founded Rubrik. The product began as workplace search; its homepage now describes an enterprise AI platform that connects a company's data and tools to find information, create content and automate work. It is headquartered in Palo Alto, California.

Key features

Per its product page, Assistant searches company tools, documents, conversations and the web, plans multi-step work and returns cited results. Agents are described as AI coworkers acting across systems (beta). The platform also generates documents, slide decks and dashboards, analyses data and summarises meetings. The company says it offers 275+ connectors and access to 40+ large language models. Developers get a Client API, Indexing API and MCP server.

Pricing and value

Glean publishes no pricing and only offers a demo request. Some third-party pages give per-user monthly estimates and seat minimums, but most are written by competitors, the figures differ and the vendor has not confirmed them, so this review does not use them. Real cost requires a quote.

More analysis

Who it is for

Glean targets large enterprises, with named customers such as Booking.com, Zillow, TIME and Ericsson. It raised a $150 million Series F in 2025 at a $7.2 billion valuation and says annual recurring revenue passed $100 million. Teams already on Microsoft 365 or Google Workspace that only need an assistant inside that ecosystem should compare the built-in assistants first.

The pages read give no refund policy; terms are set by enterprise contract.

Privacy

Glean lists ISO 42001, ISO 27001, SOC 2 Type II, HIPAA, TX-RAMP Level 2 and GDPR. Its security page says the platform checks source-system permissions on reads and writes, verifies users and agents through the customer's SSO, and keeps an end-to-end audit trail that can stream to a SIEM. That page does not cover encryption, retention or whether customer data trains models; details sit in its Trust Center. The privacy policy (updated 1 April 2026) covers Glean's websites and business operations, not its Solutions; when Glean processes data for your employer it acts as processor and the organisation is the controller. The policy says Glean does not sell personal information and gives no specific retention periods.

Review evidence & sources9

Scores

Ease of use
7.5
Why this score

Gartner Peer Insights sits at 4.5/5, but enterprise rollout needs many connectors and permission setup; the pages read have no separate ease-of-use data. The interface is English-only.

Features
8.0
Why this score

Covers search, assistant, agents, data analysis, content creation and APIs with 275+ connectors; part is still beta.

Value for money
6.0
Why this score

Unpublished pricing makes comparison hard; third-party estimates exist but are mostly written by competitors and are not reliable enough to use.

Performance
7.5
Why this score

The vendor claims 99.9%+ uptime for core search and AI services, but this is self-reported.

Support
6.5
Why this score

Developer docs, a Trust Center and a bug bounty exist; the pages read do not describe concrete support commitments.

Privacy & security
7.5
Why this score

Many certifications, source-system permission checks and an audit trail; the security page omits encryption, retention and model-training details.
