Glean Technologies, Inc. is an American technology company specializing in enterprise-grade artificial intelligence (AI) and search capabilities. Founded in 2019 by a seasoned team of former Google search engineers and industry veterans—including Arvind Jain (CEO), T.R. Vishwanath, Tony Gentilcore, and Piyush Prahladka—the company was established to address the growing challenge of information fragmentation in modern workplace environments. Headquartered in Palo Alto, California, Glean operates a cloud-based Work AI platform designed to unify enterprise search, assistants, and agents across an organization’s entire data footprint. The core of Glean's product offering is an AI-powered search engine that securely connects with over 100 workplace applications, such as Slack, Figma, Box, GitLab, Google Workspace, and Asana. By indexing this disparate company data, the platform provides permission-aware search results, enabling employees to find answers and relevant documents quickly. In 2021, Glean introduced an generative AI assistant that delivers highly personalized answers grounded in a company’s unique enterprise knowledge graph, ensuring data privacy and referenceable sourcing. Expanding its capabilities further in 2025, the company launched its agent platform, allowing users to deploy low-code and no-code AI agents designed to automate complex, multi-step workflows using natural language instructions. Glean operates as a private, venture-backed entity and has experienced rapid financial growth. In February 2025, the company reported reaching $100 million in annual recurring revenue (ARR), which surged past $300 million by mid-2026. This growth has been driven by widespread enterprise adoption across various industries, counting global brands like Booking.com, Zillow, Ericsson, TIME, and GCash among its clients. To further its technical capabilities, Glean completed its first major acquisition by merging with Aryn, an AI and software development company, in March 2026. The company's rapid expansion has been supported by significant venture capital funding, totaling $765 million across six major rounds. Glean achieved unicorn status in May 2022 following a $100 million Series C round. By September 2024, its Series E round co-led by Altimeter Capital and DST Global valued the company at $4.6 billion. Most recently, on June 10, 2025, Glean secured $150 million in Series F financing led by Wellington Management, alongside participation from prominent investors such as Sequoia Capital, Lightspeed Venture Partners, General Catalyst, and Kleiner Perkins, elevating its valuation to $7.2 billion. As of May 2026, Glean's global workforce has grown to approximately 1,648 employees, including its regional subsidiary, Glean Search Technologies India Private Limited, established in Bangalore to support its expanding operations.
