Glean ARR Hit $250M

Glean is an enterprise “Work AI” platform designed to help organizations unlock knowledge and automate workflows using artificial intelligence. Founded by former Google engineer Arvind Jain, the platform connects to tools like Google Workspace, Slack, Microsoft 365, Salesforce, and dozens of other enterprise systems to create a unified knowledge layer across a company.

Employees can ask questions in natural language, generate documents, summarize internal information, or automate tasks using AI agents that understand organizational context. By solving the problem of fragmented corporate data and inefficient information retrieval, Glean enables teams to find knowledge instantly and turn it into actionable insights directly within their existing workflows. 

The company has experienced extraordinary growth as enterprises adopt AI for daily operations. Glean surpassed $200 million in annual recurring revenue (ARR) just nine months after hitting the $100 million milestone, making it one of the fastest-growing enterprise AI software companies of the decade.

More recently, internal updates from the company indicate the platform has exceeded $250 million ARR with more than 150% year-over-year growth, reflecting strong demand for AI-powered productivity tools across global enterprises. The platform also sees heavy engagement, with employees running multiple AI queries daily and businesses integrating Glean into mission-critical workflows such as product development, incident response, audits, and customer support. 

On the funding side, Glean has raised hundreds of millions of dollars from top venture investors including Sequoia Capital, Lightspeed Venture Partners, and Kleiner Perkins. In 2025 the company raised a $150 million Series F round at a $7.2 billion valuation, up from $4.6 billion just months earlier.

Since launching only a few years ago, Glean has grown from early enterprise search software into a broader AI platform that includes AI assistants, autonomous agents, and an expanding ecosystem of more than 100 enterprise integrations. With rapid ARR growth, deep enterprise adoption, and continued investment in AI infrastructure, Glean is positioning itself as a foundational “AI operating layer” for the modern workplace.
