Glean is an enterprise AI platform founded in 2019 by Arvind Jain, a former Google distinguished engineer and Rubrik co-founder, along with co-founders including T.R. Vishwanath, Piyush Prahladka, and Tony Gentilcore. The company builds a unified Work AI layer that connects to a company's applications and knowledge so employees can search, ask questions, and run AI agents grounded in their organization's own data.
The platform's core components include Glean Assistant, a personalized AI assistant; Glean Agents for automating work across departments; Glean Search across more than 100 integrated applications; and Glean Protect for permissions, security, and governance. A central design principle is enforcing existing access controls so that AI responses respect each user's document permissions.
Glean serves large enterprises across engineering, sales, support, marketing, HR, and IT, with customers including well-known technology and consumer brands. It positions itself around measurable productivity outcomes, citing significant time savings per user and relatively fast return on investment for deployed organizations.
The company competes with both horizontal AI assistants and other enterprise search and knowledge platforms. Its differentiation centers on broad connector coverage, permission-aware retrieval, and an agent platform built specifically for enterprise governance rather than a general-purpose chatbot.
Glean is best understood as a knowledge-and-agents layer for medium and large organizations with substantial internal content and many SaaS tools. Value depends on connector coverage for a company's stack and on data hygiene, and it is less relevant for very small teams with limited internal knowledge or budget.
