Glean review
Permission-aware search and AI agents across everything your company already uses.
TECHi verdict
Glean is what enterprise AI looks like when someone does the unglamorous work first. The permissions mirror — every answer filtered by what that user could already see — is the feature that gets it past security review while flashier assistants stall, and tripling ARR to a reported $300 million while Microsoft gives Copilot away suggests the moat is real. Two cautions before buying. First, the price: opaque, custom-quoted, and heavy enough that you should honestly model it against 'do nothing plus ChatGPT Enterprise.' Second, Glean amplifies your knowledge base as-is — organizations with rotten documentation buy themselves a faster route to wrong answers. Right buyer: a 1,000-plus-seat company with sprawling SaaS and a real knowledge-management culture. Wrong buyer: anyone hoping software will substitute for one.
Pros
- + Hundred-plus connectors feed one knowledge graph, so a single query spans Slack, Drive, Jira, Salesforce, and the long tail
- + Answers mirror each user's live permissions — the single feature that gets AI past enterprise security review
- + Glean Agents extends search into automation, with the company reporting a pace of a billion agent actions a year
Watchouts
- - No public pricing and reported ~100-seat minimums shut out smaller teams and make budgeting a negotiation
- - Answer quality tracks the freshness of what's indexed — stale wikis produce confident, current-sounding wrong answers
