Glean

The Palo Alto enterprise-search company founded in 2019 by former Google search engineer and Rubrik co-founder Arvind Jain, which indexes a company's documents, messages and tickets across dozens of software suites and puts an AI assistant and, from 2025, AI agents on top. Glean's bet is neutrality: a large company that uses Microsoft, Google, Salesforce, Atlassian, Slack and ServiceNow at once needs one layer that searches all of them with each user's permissions intact, and no single suite vendor will build that layer fairly. The bet paid off quickly once generative AI arrived: Glean reported $100m of annual recurring revenue (ARR) in its fiscal year to January 2025 (company, 5 February 2025), $200m in December 2025 (company) and ~$300m by late May 2026 (company, reported), and raised at $7.2bn in June 2025. The same years exposed its main weakness: the suites whose data Glean indexes are also its competitors, and in 2025 Salesforce restricted how third parties could store and index Slack data.
