American leading enterprise AI search startup Glean successfully raised $150 million in its Series F financing, reaching a valuation of $7.2 billion. This round was led by Wellington Management and saw a 57% increase from its $4.6 billion valuation in September 2024, highlighting the strong demand for AI-driven enterprise solutions in the market.
This funding round attracted participation from numerous new investors including Khosla Ventures, Bicycle Capital, Geodesic Capital, and Archerman Capital, as well as existing investors such as Altimeter, Capital One Ventures, Citi, Coatue, DST Global, General Catalyst, ICONIQ, IVP, Kleiner Perkins, Latitude Capital, Lightspeed Venture Partners, and Sequoia Capital. This robust investor lineup reflects unwavering confidence in Glean's mission to transform enterprise knowledge management through AI.
Glean, founded in 2019 by former Google search engineers, has quickly become a key player in the enterprise AI sector. Its AI-driven platform seamlessly integrates with workplace tools like Google Workspace, Microsoft 365, Slack, and Salesforce, offering efficient search and automation features. Its flagship product, the Glean Agents platform launched in February 2025, supports over 100 million automated operations annually and plans to reach 1 billion by year-end. Glean’s annual recurring revenue has exceeded $100 million, achieving this milestone within less than three years of launching its software.
This financing will be used to accelerate Glean's strategic initiatives, including deepening innovation in AI security, enterprise search, and agent AI, expanding its international presence, and opening a new office in San Francisco to support its growing team of over 850 employees. The first-ever user conference, Glean:GO held last month, attracted 10,000 attendees, showcasing significant market appeal. Glean has also formed partnerships with industry leaders such as Dell, Palo Alto Networks, and Snowflake.
Despite challenges such as Salesforce's recent restriction on AI platform data access for Slack, Glean remains committed to helping businesses unlock the potential of collective knowledge. Glean's valuation surge aligns with broader industry trends, as AI startups have attracted nearly half of U.S. venture capital over the past year. The global AI agent market is expected to grow from $7.6 billion in 2025 to $52.6 billion by 2030, positioning Glean to capitalize on this growth momentum.
Glean's rapid rise, inclusion in CNBC's Disruptor 50 list, and Fast Company's 2025 ranking as one of the ten most innovative companies highlight its increasing influence in reshaping how enterprises enhance productivity and decision-making capabilities through AI.
