Glean, gen AI enterprise search startup, raises $150 million in deal adding billions to valuation

In a significant move for the enterprise search sector, Glean, a startup specializing in generative AI, has successfully raised $150 million in its Series F funding round. This influx of capital has propelled the company’s valuation to an impressive $7.2 billion, marking a remarkable increase from the $4.6 billion valuation established just nine months earlier. Glean's rapid ascent has not gone unnoticed, as the company has earned a spot on the CNBC Disruptor 50 list for the second consecutive year. The startup reported that its annual recurring revenue exceeded $100 million for the fiscal year ending January 31, 2025, a remarkable feat considering it was founded less than three years ago by a team with backgrounds from tech giants like Google, Meta, and Dropbox. Arvind Jain, co-founder and CEO of Glean, emphasized the company's mission to integrate AI into daily work processes, stating, "We're building the platform that brings AI into the fabric of everyday work, connecting people to knowledge, automating tasks, and enabling smarter decisions across the enterprise." In early 2025, Glean introduced its new agentic AI, known as Glean Agents, which the company anticipates will facilitate a staggering one billion actions by the end of the year. The core of Glean's offering is its AI-driven enterprise search platform, designed to seamlessly integrate with popular workplace applications such as Google Workspace, Microsoft 365, Slack, and Salesforce. Glean utilizes advanced natural language processing and machine learning techniques to craft personalized knowledge graphs for users, enhancing search outcomes and automating workflows. Initially catering to tech clients, Glean has diversified its scope to include sectors like finance, retail, and manufacturing. Jain revealed in an interview that the newly raised funds will enable Glean to expand its research and development and sales teams, while also targeting larger enterprises and international markets. He noted that many organizations are anxious about the generative AI revolution, expressing a desire to adopt AI-driven strategies rapidly to avoid falling behind. Wellington Management led the recent funding round, with participation from existing investors including Capital One Ventures, Altimeter, and Sequoia Capital, among others. New investors such as Khosla Ventures and Bicycle Capital also joined in the latest investment. While consumer-focused generative AI is experiencing rapid growth, Jain highlighted the unique challenges of the enterprise market, which requires a tailored approach. He pointed out that models like ChatGPT lack access to internal company data, whereas Glean's technology integrates contextual data to address specific business needs effectively. As Glean continues to thrive in a competitive landscape that includes formidable players like Microsoft 365 Copilot and Amazon Q Business, Jain remains confident in the company's innovative edge. "We have a lead and deep enterprise technology that we built over these years. We have to keep innovating to stay ahead of the curve," he stated. With its headquarters in Palo Alto, Glean is set to open a new office in San Francisco as part of its growth strategy.
