Glean

Overview

Glean is an enterprise-grade AI platform that unifies fragmented workplace data into a single, searchable knowledge graph. It enables employees to find information, generate answers, and automate tasks across hundreds of SaaS applications like Slack, Jira, and Google Workspace. By prioritizing strict permissioning and context-aware retrieval, Glean serves as a secure, neutral AI layer for large-scale organizations.

What it does

• • Indexes and connects data across 300+ enterprise applications to create a unified, real-time knowledge repository for users
• • Provides a conversational AI assistant that generates accurate, cited answers based on private company data and documents
• • Employs patented 'Permissions-Aware Indexing' to ensure users only see content they have authorized access to, preventing data leaks
• • Offers a centralized platform for building custom AI agents and applications that leverage the company's secure internal search index
• • Operates as a neutral infrastructure layer, allowing businesses to integrate with various cloud providers, LLMs, and security partners.

Who it's for

• Enterprise Organizations
• IT & Knowledge Management Teams
• Global Workforce
• Corporate Security & Compliance Teams

Why it works

• Deep integration with existing enterprise ecosystems provides a comprehensive context that generic AI models cannot access or interpret
• Strict security and governance features enable highly regulated industries like financial services and healthcare to deploy AI securely
• Agentic reasoning allows for task automation beyond simple search, shifting from information discovery to tangible work completion
• Neutral, cross-platform architecture prevents vendor lock-in, allowing companies to evolve their AI and cloud infrastructure over time
• Real-time, permission-aware indexing ensures that all AI-generated outputs remain relevant, secure, and compliant with internal data access policies.

Founder story

Founded in 2019 in Palo Alto, California, by former Google search engineers Arvind Jain, T.R. Vishwanath, Tony Gentilcore, and Piyush Prahladka. Frustrated by the productivity loss caused by information fragmentation across sprawling SaaS environments, the founders leveraged their deep expertise in search and systems engineering to build a 'Google for Work' that respects enterprise privacy.
