Glean Raises $150M in Series F, Valuation Soars to $7.2 Billion

Enterprise AI startup Glean has secured $150 million in a Series F funding round led by Wellington Management, pushing its valuation to an impressive $7.2 billion. This marks a significant leap in value for the company, which was last valued at $4.6 billion during its Series E round just nine months ago.

Rapid Growth in Funding and Valuation

Since early 2024, Glean has raised a total of $610 million, experiencing a remarkable growth trajectory. Back in February, the company stood at a $2.2 billion valuation. By September, it doubled to $4.6 billion, and now it has grown further to $7.2 billion—more than tripling in under a year. This rapid increase reflects investor confidence in the company’s technology and its potential to redefine enterprise search with artificial intelligence.

Crossing $100 Million in ARR

In addition to its fundraising success, Glean reported that it has crossed $100 million in annual recurring revenue (ARR) in its most recent fiscal year. Achieving this milestone in just three years since launch puts Glean among a select group of enterprise startups scaling at a breakneck pace. This fast growth in both revenue and valuation indicates a strong demand for its AI-driven offerings in the enterprise software space.

What Glean Does

Glean’s core product allows employees at large companies to search internal documents and information across platforms using natural language queries. By integrating with enterprise tools like Salesforce, Microsoft Teams, and Zendesk, Glean helps users quickly find the information they need, regardless of where it’s stored. The system leverages large language models (LLMs) to provide accurate, context-aware search results.

Beyond search, Glean has also expanded into building AI agents—virtual assistants that can automate tasks and improve productivity within the workplace. These agents further its mission of using artificial intelligence to streamline operations and help teams work more efficiently.

Investors Backing Glean’s Vision

The Series F round attracted participation from a wide range of investors, both new and existing. Alongside Wellington Management, contributors included Khosla Ventures, Bicycle Capital, Geodesic Capital, and Archerman Capital. Returning backers also joined in, such as Altimeter, Capital One Ventures, Citi, Coatue, DST Global, General Catalyst, ICONIQ, IVP, Kleiner Perkins, Latitude Capital, Lightspeed Venture Partners, Sapphire Ventures, and Sequoia Capital.

The strong participation from such a diverse group of high-profile investors underscores Glean’s credibility and its growing influence in the enterprise AI space.

Looking Ahead

With fresh capital and strong momentum, Glean is poised to continue its rapid expansion. Its ability to hit $100 million in ARR within three years, combined with its growing portfolio of AI tools, suggests it is on track to become a major player in the enterprise software market. As businesses increasingly adopt AI-powered solutions, Glean appears well-positioned to lead the way.
