Glean

Glean, founded in 2019 by Arvind Jain, Vishwanath T R, Tony Gentilcore, and Piyush Prahladka, is an enterprise AI platform that connects a company's data across systems so employees can search, build workflows, and automate work using institutional knowledge — used by Booking.com, Zillow, TIME Magazine, and Ericsson. It connects to 35+ LLMs and integrates with Slack, Google Drive, Jira, Confluence, SharePoint, GitHub, and Salesforce, provides permission-aware enterprise search across fragmented knowledge, and lets teams build and deploy no-code AI agents. The company claims a 30% reduction in token usage versus comparable tools, and holds ISO 42001, HIPAA, SOC 2 Type II, ISO 27001, and GDPR certifications. No pricing is published; access requires contacting sales, typical for enterprise search/AI infrastructure sold to large organizations. Good fit for an enterprise whose institutional knowledge is scattered across many systems and wants unified, permission-aware search and agent-building on top of it.
